在 Linux 下安装 PHP5 与 PHP7 共存。
PHP5 安装
- PHP 官网 www.php.net
- 当前主流版本为 5.6/7.1
- 进入存储源码包的目录:
[root@linuxidc ~]# cd /usr/local/src
- 下载 php 的源码包:
地址:wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
5. 解压压缩包:
[root@linuxidc src]# tar -zxvf php-5.6.30.tar.gz
6. 进入安装目录:
[root@linuxidc src]# cd php-5.6.30
[root@linuxidc php-5.6.30]#
7. 安装 php:
[root@linuxidc php-5.6.30]# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --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 // 安装 PHP
[root@linuxidc php-5.6.30]# echo $? // 安装完成没有错误用这个检查
0
解释说明个别参数:
--prefix:指定安装目录。
--with-apxs2:Apache 的工具,指定工具的地址,可以帮我们自动配置一些模块, 不用人工干涉。
--with-config-file-path:指定配置文件的路径。
--with-mysql:指定 mysql 路径。
安装报错:
- 缺少 libxml2 这个库,安装命令:yum install -y libxml2-devel
- 缺少 openssl 库,安装命令:yum install -y openssl-devel
- 缺少 bzip2 包,安装命令:yum install -y bzip2-devel
- 缺少 jpeglid 包, 安装命令:yum install -y libjpeg-devel
- 缺少 libpng 包,安装命令:yum install -y libpng-devel
- 缺少 freetype 包,安装命令:yum install -y freetype-devel
- 缺少 libmcrypt 包,安装命令:yum install -y libmcrypt-devel,如果你没有安装 epel-release 这个扩展源,就需要先安装这个扩展源,因为 libmcrypt 是在这个扩展源里面,安装扩展源命令:yum install -y epel-release
8. 编译安装
[root@linuxidc php-5.6.30]# make
[root@linuxidc php-5.6.30]# make install
[root@linuxidc php-5.6.30]# echo $?
0
备注:Apache 和 php 结合的通过图中的 libphp5.so 模块
9. 查看 php 加载的模块(都是静态的):
[root@linuxidc php-5.6.30]# /usr/local/php/bin/php -m

10.PHP 是做为 apache 的模块存在,查看模块:
[root@linuxidc php-5.6.30]# /usr/local/apache2.4/bin/httpd -M
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 218.93.250.18. Set the'ServerName' directive globally to suppress this message

[root@linuxidc php-5.6.30]# ls -l /usr/local/apache2.4/modules/libphp5.so // 模块文件
-rwxr-xr-x 1 root root 37752872 12 月 18 17:09 /usr/local/apache2.4/modules/libphp5.so
解释说明:
php5_module (shared):这个说明 PHP 是作为 httpd 扩展模块的形式存在的, 那如果 apache 要想执行 php 的脚本,它就需要依赖借助于这个模块文件,如果把这个.so 文件删除,那 apache 就不支持 php 了,这个模块非常重要。
11. 这个 httpd 的配置文件里就多了一行 php 模块,被注释掉的就是没有用的模块,如果想用,把 #号去掉就可以了,随用随取:
[root@linuxidc php-5.6.30]# vim /usr/local/apache2.4/conf/httpd.conf // 这是 apache 的配置文件
12. 把 php 的参考配置文件复制到 php 的配置文件目录下:
示例如下:
[root@linuxidc php-5.6.30]# /usr/local/php/bin/php -i |less // 查看 php 的一些配置信息,包括编译参数。
phpinfo()

PHP7 安装
- 进入源码包的目录:
[root@linuxidc ~]# cd /usr/local/src/
2. 下载源码包:
地址:wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
3. 解压压缩包:
[root@linuxidc src]# tar jxvf php-7.1.6.tar.bz2
备注:如果没有安装 bzip2 压缩工具,请安装:yum install -y bzip2
4. 进入目录:
[root@linuxidc src]# cd php-7.1.6
[root@linuxidc php-7.1.6]#
5. 安装 php7:
[root@linuxidc 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
6. 编译安装:
[root@linuxidc php-7.1.6]# make
[root@linuxidc php-7.1.6]# make install
7.php7 模块路径:
[root@linuxidc php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
8. 查看 php7 加载的模块(静态):
[root@linuxidc php-7.1.6]# /usr/local/php7/bin/php -m

9. 查看 apache 加载了几个 php, 通过修改配置文件来指定使用 php5 还是 php7 模块,不要的就注释掉:
示例如下:
[root@linuxidc 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 218.93.250.18. Set the'ServerName' directive globally to suppress this message

[root@linuxidc php-7.1.6]# vim /usr/local/apache2.4/conf/httpd.conf
10. 把 php7 的参考配置文件复制到 php7 的配置文件目录下:
[root@linuxidc php-7.1.6]# cp php.ini-production /usr/local/php7/etc/php.ini
