CentOS7.0+PHP5.6环境搭建

本文是基于Centos7.0搭建的，安装php，有两种方式安装，一种是通过源码编译安装，一种是通过yum安装，yum安装很简单，直接输入yum -y install php即可，默认安装的是php5.4版本的，这里要安装php5.6，所以选择源码安装的方式。

安装php之前，需要先安装以下依赖：

yum install openssl openssl-devel libxml2-devel libxml2 bzip2 bzip2-devel curl-devel php-mcrypt libmcrypt

libmcrypt-devel readline-devel

其中由于默认的yum源没有 libmcrypt-devel这个包,只能借助epel的yum源,所以先安装epel,再安装libmcrypt：

yum install -y epel-release

yum install -y libmcrypt-devel

如果找不到epel的话，就得更换源或者直接下载libmcrypt源码包编译，这个很简单，不展示了。

下载php5.6源码：

wget http://mirrors.sohu.com/php/php-5.6.31.tar.gz

解压源码包：

tar xzvf php-5.6.31.tar.gz

cd php-5.6.31

配置编译选项：

    ./configure --prefix=/usr/local/php \
    --with-config-file-path=/usr/local/php/etc \
    --enable-inline-optimization \
    --disable-debug \
    --disable-rpath \
    --enable-shared \
    --enable-opcache --enable-fpm \
    --with-fpm-user=www \
    --with-fpm-group=www \
    --with-mysql=mysqlnd \
    --with-mysqli=mysqlnd \
    --with-pdo-mysql=mysqlnd \
    --with-gettext \
    --enable-mbstring \
    --with-iconv \
    --with-mcrypt \
    --with-mhash \
    --with-openssl \
    --enable-bcmath \
    --enable-soap \
    --with-libxml-dir \
    --enable-pcntl \
    --enable-shmop \
    --enable-sysvmsg \
    --enable-sysvsem \
    --enable-sysvshm \
    --enable-sockets \
    --with-curl \
    --with-zlib \
    --enable-zip \
    --with-bz2 \
    --with-readline \

--with-apxs2=/usr/bin/apxs

其中，最后一项--with-apxs2=/usr/bin/apxs中apxs是在安装了apache（httpd）之后才存在。

在configure时添加--with-apxs2=/usr/bin/apxs的原因是为了生成libphp5.so给到apache（httpd）使用，否则apache打开php文件时会出现下载界面，而不做解析，这个在配置apache支持php module的时候会提到，这里不加此选项也可以，新版本的php都支持动态添加模块，也就是说，后面如果需要此模块，再单独configure即可。

configure成功后，会出现以下内容：

接着执行make，经过一段时间的等待，会看到以下内容：

Build complete.
Don't forget to run 'make test'.

虽然它提示要执行make test，不过我本人测试过，会出现以下类似问题：

目前还没解决，如果有已经解决的高手，帮忙告知下，谢谢！

此问题对使用php影响不大，所以暂时忽略以上问题。

接着继续执行：

make install

成功的话可以看到以下结果：

添加环境变量：

vi /etc/profile

在末尾加入：

PATH=$PATH:/usr/local/php/bin

export PATH

使改动立即生效：

source /etc/profile

然后php -v，可以看到：

Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

进入php安装包路径，拷贝配置文件：

cd php-5.6.31

    cp php.ini-production /usr/local/php/etc/php.ini
    或者
    cp php.ini-development /usr/local/php/etc/php.ini

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

cp . /sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

chmod a+x /etc/init.d/php-fpm

此时手动启动php-fpm，发现报错：

/usr/local/php/sbin/php-fpm

报错：

ERROR: [pool www] cannot get uid for user '@php_fpm_user@'
ERROR: FPM initialization failed

解决办法：

vi   /usr/local/php/etc/php-fpm.conf 
把 user 和 group 修改为当前用户和用户组即可。

接着将php-fpm服务添加到chkconfig列表：

chkconfig --add php-fpm

设置开机自启动：

chkconfig php-fpm on

以后重启和停止php的方式为：

    service php-fpm start
    service php-fpm stop
    service php-fpm restart

service php-fpm reload

查看是否启动成功：
