11.13 安装PHP7 - 码农教程

安装PHP7目录概要

cd /usr/local/src/
wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
tar zxf php-7.1.6.tar.bz2
cd php-7.1.6
./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
make && make install
ls /usr/local/apache2.4/modules/libphp7.so
cp php.ini-production /usr/local/php7/etc/php.ini

安装过程php7

首先切换到/usr/local/src/目录下

[root@hf-01 php-5.6.30]# cd /usr/local/src/
[root@hf-01 src]#

然后下载PHP7.1版本安装包

[root@hf-01 src]# wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2

查看PHP7安装包，并解压

[root@hf-01 src]# ls
apr-1.6.3               mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz
apr-1.6.3.tar.gz        mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
apr-util-1.6.1          php-5.6.30
apr-util-1.6.1.tar.bz2  php-5.6.30.tar.gz
httpd-2.4.29            php-7.1.6.tar.bz2
httpd-2.4.29.tar.gz
[root@hf-01 src]# tar jxvf php-7.1.6.tar.bz2    //解压php7.1版本

进入到PHP7的源码包目录下/usr/local/src/php-7.1.6/

[root@hf-01 src]# cd php-7.1.6/
[root@hf-01 php-7.1.6]#

初始化配置
- 这里php7和php5的区别
  - --prefix=/usr/local/php7这里定义的目录名字是php7
  - --with-config-file-path=/usr/local/php7/etc这里定义的配置文件路径是php7
  - 这里只有--with-mysqli，没有--with-mysql，而其他的都类似

[root@hf-01 php-7.1.6]# ./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc  --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif

在初始化配置完成后，然后make && make install

[root@hf-01 php-7.1.6]# make && make install

这样php7.1就安装成功了

小知识（安装两个php）

一台机器上安装两个php，两个PHP是可以同时存，但是Apache调用PHP的时候，需要指定好，在——> vim /usr/local/apache2.4/conf/httpd.conf 里面指定使用哪一个PHP即可

查看PHP7的文件

查看libphp7和5是不同的，/usr/local/apache2.4/modules/libphp7.so

[root@hf-01 php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
[root@hf-01 php-7.1.6]# du -sh !$        //查看php7大小
du -sh /usr/local/apache2.4/modules/libphp7.so
37M	/usr/local/apache2.4/modules/libphp7.so
[root@hf-01 php-7.1.6]#

查看php7所加载的模块，/usr/local/php7/bin/php -m，和php5基本是一致的

[root@hf-01 php-7.1.6]# /usr/local/php7/bin/php -m
[PHP Modules]

[Zend Modules]

[root@hf-01 php-7.1.6]#

查看Apache加载了几个php
- 会看到加载了php5和php7

[root@hf-01 php-7.1.6]# /usr/local/apache2.4/bin/apachectl -M
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 192.168.0.104. Set the 'ServerName' directive globally to suppress this message

[root@hf-01 php-7.1.6]#

若想去使用哪一个PHP，根据自己的实际需求

[root@hf-01 php-7.1.6]# vim /usr/local/apache2.4/conf/httpd.conf

搜索php5.so，会看到有两行
LoadModule php5_module        modules/libphp5.so
LoadModule php7_module        modules/libphp7.so

想使用哪个php，就在另一个前面加 # 号注释掉，然后保存
