Linux系统下为Nginx安装多版本PHP

我们在安装配置服务器LNPM环境时应该考虑到PHP多版本并存的问题，下面是实现Linux系统下为Nginx安装多版本PHP的实现方法

linux版本：64位CentOS 6.4

Nginx版本：nginx1.8.0

php版本：php5.5.28 &php5.4.44

注意假如php5.5是主版本已经安装在/usr/local/php目录下，那么再安装其他版本的php再指定不同安装目录即可。

安装PHP

# wget http://cn2.php.net/get/php-5.4.44.tar.gz/from/this/mirror
# tar zxvf php-5.4.44.tar.gz
# cd php-5.4.44
#./configure --prefix=/usr/local/php5.4.44 
--with-curl 
--with-freetype-dir 
--with-gd 
--with-gettext 
--with-iconv-dir 
--with-kerberos 
--with-libdir=lib64 
--with-libxml-dir 
--with-mysql 
--with-mysqli 
--with-openssl 
--with-pcre-regex 
--with-pdo-mysql 
--with-pdo-sqlite 
--with-pear 
--with-png-dir 
--with-xmlrpc 
--with-xsl 
--with-zlib 
--enable-fpm 
--enable-bcmath 
--enable-libxml 
--enable-inline-optimization 
--enable-gd-native-ttf 
--enable-mbregex 
--enable-mbstring 
--enable-pcntl 
--enable-shmop 
--enable-soap 
--enable-sockets 
--enable-sysvsem 
--enable-xml 
--enable-zip
# make && make install
# cp -R ./sapi/fpm/php-fpm.conf /usr/local/php5.4.44/etc/php-fpm.conf
# cp php.ini-development /usr/local/php5.4.44/lib/php.ini
# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm5.4.44

修改php-fpm.conf的侦听端口为9001，因为主版本5.5.28是侦听9000。

; Note: This value is mandatory.
listen = 127.0.0.1:9001

启动php-fpm

# /etc/init.d/php-fpm5.4.44

php安装成功查看进程

#ps aux|grep php

这样就已经起好php-fpm了。

配置Nginx

增加一段新的端口8054的配置并指向到9001以及指定目录即可：

server {
    listen    8054;
    server_name localhost;


    location / {
      #root  html;
root /usr/www5.4.44;
      index index.html index.htm;
    }


    error_page  500 502 503 504 /50x.html;
    location = /50x.html {
      root  html;
    }


location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/www5.4.44$fastcgi_script_name;
}
 
  }

nginx的配置文件nginx.conf在

# cd /usr/local/nginx/conf

完整的nginx配置如下：

#user nobody;
worker_processes 4;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid    logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include    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 logs/access.log main;
sendfile    on;
#tcp_nopush   on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen    80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
#root  html;
root /usr/www;
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  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$fastcgi_script_name;
#  include    fastcgi_params;
#}
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/www$fastcgi_script_name;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /.ht {
#  deny all;
#}
}
server {
listen    8054;
server_name localhost;
location / {
#root  html;
root /usr/www5.4.44;
index index.html index.htm;
}
error_page  500 502 503 504 /50x.html;
location = /50x.html {
root  html;
}
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/www5.4.44$fastcgi_script_name;
}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#  listen    8000;
#  listen    somename:8080;
#  server_name somename alias another.alias;
#  location / {
#    root  html;
#    index index.html index.htm;
#  }
#}
# HTTPS server
#
#server {
#  listen    443 ssl;
#  server_name localhost;
#  ssl_certificate   cert.pem;
#  ssl_certificate_key cert.key;
#  ssl_session_cache  shared:SSL:1m;
#  ssl_session_timeout 5m;
#  ssl_ciphers HIGH:!aNULL:!MD5;
#  ssl_prefer_server_ciphers on;
#  location / {
#    root  html;
#    index index.html index.htm;
#  }
#}
}

重启nginx

# /usr/local/nginx/sbin/nginx -s reload

注意需要防火墙增加新端口的开启，不然无法访问：

防火墙配置

注意如果你希望在本地机器例如xp访问虚拟机的网页，如果是centos6需要修改防火墙启动80端口

# cd /etc/sysconfig

修改iptables文件，或者直接用vim编辑

# vim /etc/sysconfig/iptables

添加下面一行，打开防火墙80端口:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8054 -j ACCEPT

重启防火墙

# /etc/init.d/iptables restart

测试是否成功，查看phpinfo()
