}
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
三、web环境搭建
3.1、Nginx安装配置
(1) 镜像拉取
[root@localhost ~]# docker pull nginx:1.18.0
(2) 创建数据目录
[root@localhost ~]# mkdir -pv /lnmp/nginx/{conf/conf.d,data,logs}
(3) 准备配置文件 nginx.conf 与 conf.d/default.conf
[root@localhost ~]# vim /lnmp/nginx/conf/nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
[root@localhost ~]# vim /lnmp/nginx/conf/conf.d/default.conf
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
(4) 启动容器
[root@localhost ~]# docker run -d --name nginx \
-p 80:80 \
-v /lnmp/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /lnmp/nginx/conf/conf.d:/etc/nginx/conf.d \

; '-p' argument from the command line.
; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:

; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)
; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]
; Per pool prefix
; It only applies on the following directives:
; - 'access.log'
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;

; Note: This value is mandatory.
listen = 127.0.0.1:9000
; Set listen(2) backlog.
; Default Value: 65535 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 65535
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0660
;listen.owner = www-data
;listen.group = www-data
;listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =
; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1
; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
; - The pool processes will inherit the master process priority
; unless it specified otherwise
; Default Value: no set
; process.priority = -19
; Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user
; or group is differrent than the master process user. It allows to create process
; core dump and ptrace the process for the pool user.
; Default Value: no
; process.dumpable = yes
; Choose how the process manager will control the number of child processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on the
; following directives. With this process management, there will be
; always at least 1 children.
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 5
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 2
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 1
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 3
; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;
; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500
; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460
; listen queue: 0
; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.

; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow
; The timeout for serving a single request after which a PHP backtrace will be

; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes
; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no
; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5
; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp
; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines which can
; be overwritten from PHP call 'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.
; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local)
; Default Value: nothing is defined by default except the values in php.ini and
; specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M
(5) 启动容器
[root@localhost ~]# docker run -d --name php-fpm \
-p 9000:9000 \
-v /lnmp/php-fpm/www.conf:/data/php-fpm/etc/php-fpm.d/www.conf \
-v /lnmp/nginx/html:/var/www/html \
php:5.6-fpm
(6) 修改nginx的 default.conf 配置文件，使其支持解析php文件
[root@localhost ~]# vim /lnmp/nginx/conf/conf.d/default.conf
#在location段的index后加入index.php
location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
#修取fastcgi的配置注释，并修改IP和目录路径
location ~ \.php$ {
root html;
fastcgi_pass 192.168.145.87:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
include fastcgi_params;
}
[root@localhost ~]# docker restart nginx #重启nginx
(7) 测试php文件的解析
[root@localhost ~]# vim /lnmp/nginx/html/index.php
<?php
phpinfo();
?>
浏览器访问 http://192.168.145.87/index.php 查看是否正常解析，下图可以看到可以解析。
(8) 测试php连接数据库
[root@localhost ~]# vim /lnmp/nginx/html/mysql.php
<?php
$link = mysqli_connect('192.168.145.57', 'root', 'root');
if (!$link) {
die('Could not connect: ' . mysqli_connect_error());
}
echo 'Connected successfully';
mysqli_close($link);
?>
可以看到报错了，是因为还缺少连接数据库的插件，我们进入php-fpm容器，安装插件：
[root@localhost ~]# docker exec -it php-fpm /bin/bash
root@699f1deaf5c1:/var/www/html# cd /usr/local/etc/php
root@699f1deaf5c1:/usr/local/etc/php# docker-php-ext-install mysqli
root@699f1deaf5c1:/usr/local/etc/php# docker-php-ext-install mysql
root@699f1deaf5c1:/usr/local/etc/php# docker-php-ext-install pdo pdo_mysql
#一些php程序还需要安装gd库，所以我们提前先装上
#更新apt源,也可以用系统自带的源
mv /etc/apt/sources.list /etc/apt/sources.list_bak
echo "deb http://mirrors.163.com/debian/ stretch main contrib non-free\ndeb http://mirrors.163.com/debian/ stretch-updates main contrib non-free\ndeb http://mirrors.163.com/debian/ stretch-backports main contrib non-free" > /etc/apt/sources.list
#更新软件列表
root@699f1deaf5c1:/usr/local/etc/php# apt-get update
#更新软件
root@699f1deaf5c1:/usr/local/etc/php# apt-get upgrade
#安装依赖包
root@699f1deaf5c1:/usr/local/etc/php# apt-get install libpng-dev libjpeg-dev libfreetype6-dev
#安装gd库
root@699f1deaf5c1:/usr/local/etc/php# docker-php-ext-configure gd --enable-gd-native-ttf --with-freetype-dir=/usr/include/freetype2 --with-png-dir=/usr/include
root@699f1deaf5c1:/usr/local/etc/php# docker-php-ext-install gd
#然后退出容器，重启容器
root@699f1deaf5c1:/usr/local/etc/php# exit
[root@localhost ~]# docker restart php-fpm
再次测试数据库连接
可以看到已经可以了。
(9) 将容器重新生成镜像，以便后续使用
[root@localhost ~]# docker commit -m "php-fpm add extension mysql,mysqli,pdo-mysql,gd" php-fpm php-fpm:5.6.40
四、dedecms的安装
(1) 下载安装包
[root@localhost ~]# wget -c http://updatenew.dedecms.com/base-v57/package/DedeCMS-V5.7-UTF8-SP2.tar.gz
(2) 解压并将程序拷贝至网站目录
[root@localhost ~]# tar -xf DedeCMS-V5.7-UTF8-SP2.tar.gz
[root@localhost ~]# cp -r DedeCMS-V5.7-UTF8-SP2/uploads/ /lnmp/nginx/html/dedecms
(3) 修改目录权限
[root@localhost ~]# chown -R nginx.nginx /lnmp/nginx/html/dedecms/
(4) 配置网站解析，并重启nginx
[root@localhost ~]# vim /lnmp/nginx/conf/conf.d/default.conf
#添加以下内容
server {
listen 80;
server_name www.dedetest.com ;
location / {
root /usr/share/nginx/html/dedecms;
index index.html index.htm index.php;
}
location ~ \.php(.*)$ {
fastcgi_pass 192.168.145.87:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME /var/www/html/dedecms$fastcgi_script_name;
include fastcgi_params;
}
}
[root@localhost ~]# docker restart nginx
注意域名做好解析，我这里直接改的windows的host文件。
(5) 然后在浏览器输入 http://www.dedetest.com/install/index.php 进行安装
勾选协议，然后继续
这一步可以看到，目录没有写权限，解决方法为：
在宿主机新建一个www-data用户，然后进入容器，将容器中的www-data用户的uid改成用宿主机的一致
[root@localhost ~]# useradd -r -s /sbin/nologin www-data
[root@localhost ~]# id www-data
uid=996(www-data) gid=992(www-data) groups=992(www-data)
[root@localhost ~]# docker exec -it php-fpm /bin/bash
root@699f1deaf5c1:/var/www/html# usermod -u 996 www-data
root@699f1deaf5c1:/var/www/html# exit
[root@localhost ~]# chown -R www-data /lnmp/nginx/html/dedecms
或者在宿主机新建www-data用户时指定其uid为33，然后修改一下网络目录的所属组，这样就不用修改docker里的www-data的uid
[root@localhost ~]# useradd -u 33 -r -s /sbin/nologin www-data
[root@localhost ~]# chown -R www-data /lnmp/nginx/html/dedecms
还有一种方法是直接将网络目录的权限设置为777
[root@localhost ~]# chmod -R 777 /lnmp/nginx/html/dedecms
然后刷新页面再看一下目录权限，可以看到都变成可写了。
继续下一步，连接数据库，并设置网站后台密码
点“继续”，完成安装。
