apache中的php模块安装

标签：sha   edr   文件中   serve   structure   一个   long   efault   client   

安装php5
环境：安装了http和mysql服务，安装php时必须指定http和mysql的服务安装路径
首先下载对应的php版本，这里下载的是php5.6.37
解压php，并在解压目录下执行编译参数
关于编译参数解释：

./configure --prefix=/usr/local/php5 \            指定php安装目录
--with-apxs2=/usr/local/httpd/bin/apxs \         指定http目录，编译中可向http配置文件中添加php
--with-config-file-path=/usr/local/php/etc \     指定php的配置文件目录
--with-mysql=/usr/local/mysql \                  指定mysql的安装目录和mysql的库路径
--with-pdo-mysql=/usr/local/mysql \               
--with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir \                                以下是指定php需要编译支持的函数库
--with-gd \ 
--with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-sockets --enable-exif\

在php解压目录下的编译参数，对于编译中出现的错误，笔记结尾有解答

[root@localhost php-5.6.37]# ./configure --prefix=/usr/local/php5 --with-apxs2=/usr/local/httpd/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-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-sockets --enable-exif

在结合apache安装php中，php只是编译一个模块给apache使用，php模块是/usr/local/httpd/modules/libphp5.so

[root@localhost php-5.6.37]# ll -h /usr/local/httpd/modules/libphp5.so 
-rwxr-xr-x 1 root root 34M 7月 29 08:27 /usr/local/httpd/modules/libphp5.so

查看php加载的模块，使用php目录下的一个可执行文件查看，php在apache中是以模块来进行加载的，php模块就是/usr/local/httpd/modules/libphp5.so 文件， apache在解析php时会自动加载php模块文件跟数据库进行交互

[root@localhost php-5.6.37]# /usr/local/php5/bin/php -m

拷贝php的配置文件，并查看是否加载配置文件

[root@localhost ]# cp /usr/local/src/php-5.6.37/php.ini-production /usr/local/php5/etc/php.ini
[root@localhost php-5.6.37]# /usr/local/php5/bin/php -i |less

LoadModule php5_module modules/libphp5.so

php7安装

安装php7，编译过程和php5基本一致，需要修改php5安装时指定的安装目录和配置文件目录，否则安装php7时会覆盖掉php5

[root@localhost php-7.2.8]# ./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/httpd/bin/apxs --with-config-file-path=/usr/local/php7/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-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-sockets --enable-exif

拷贝php7的配置文件

让apache使用指定的php程序，只需要修改apache的配置文件，找到配置文件中php模块的配置项，把不需要加载的php配置注释掉即可

[root@localhost ]# vim /usr/local/httpd/conf/httpd.conf
~
LoadModule php5_module modules/libphp5.so
#LoadModule php7_module modules/libphp7.so         <------注释掉php7模块，不让它被apache动态加载

php编译中出现的问题

问题一：
php编译安装中有安装库报错，根据报错信息查找对应安装包，安装包软件一般是以devel结尾的，使用yum install 安装库名称-devel 可以正常安装该支持库

问题二：
解决：error: Cannot find libmysqlclient_r under /usr/local/mysql.
配置php的时候出现以下问题解决方案

checking for MySQL support... yes
checking for specified location of the MySQL UNIX socket...no
checking for MySQL UNIX socket location... no
configure: error: Cannot find libmysqlclient_r under/usr/local/mysql. Note that the MySQL client library is not bundledanymore!

其实这跟PHP没有关系，那是因为在编译APACHE的时候，使用--with-mpm模块，所以就必须在编译MYSQL的时候加上--enable-thread-safe-client.参数
这是PHP5.2的一个改进，在PHP5.2.0之前的版本都不需要MYSQL启用安全线程。关于--enable-thread-safe-client项的官方介绍如下:如何生成线程式客户端库总是线程安全的。最大的问题在于从套接字读取的net.c中的子程序并不是中断安全的。或许你可能希望用自己的告警中断对服务器的长时间读取，以此来解决问题。如果为SIGPIPE中断安装了中断处理程序，套接字处理功能应是线程安全的。SupeSite/X-为了避免连接中断时放弃程序，MySQL将在首次调用mysql_server_init()、mysql_init()或mysql_connect()时屏蔽SIGPIPE。如果你打算使用自己的SIGPIPE处理程序，首先应调用mysql_server_init()，然后安装你的处理程序.

还有第二种解决方法比较方便：编译之前，先处理一下mysql的库，默认查找libmysqlclient_r.so，可是mysql默认为libmysqlclient.so，内容完全一样，做个链接即可

# cd /usr/local/mysql/lib/mysql/ 
# ln -s libmysqlclient.so.20.0.0 libmysqlclient_r.so
