Centos7 安装php-5.6.36

1. 相关依赖包的检查与安装
   rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
   rpm -qa freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
   yum -y install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
   yum -y install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
   rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
   rpm -qa freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel

2. 安装其余依赖以其余包
   cd /home/oldboy/tools/
   wget https://ftp.gnu.org/gnu/libiconv/libiconv-1.14.tar.gz #下载安装包 ,yum源中没有
   tar zxvf libiconv-1.14.tar.gz #解压
   ./configure --prefix=/usr/local/libconv
   make
   make install

   安装libiconv软件时，可能会报错：*gets未声明，不在函数内等*

   解决方法：cd /usr/local/libiconv/srclib
   sed -i -e '/gets is a security/d' ./stdio.in.h
   3.安装其余软件
   wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
   yum -y install libmcrypt-devel
   yum -y install mhash
   yum -y install mcrypt
   4.cd /home/tools 上传php-5.6.36.tar.gz
   5.解压：tar -zxvf php-5.6.36.tar.gz
   cd php-5.6.36
   ./configure --prefix=/application/php5.6.36 \
   --with-mysql=/application/mysql \
   --with-pdo-mysql=mysqlnd \

   ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/
   touch ext/phar/phar.phar
   make
   make install
   ln -s /application/php5.6.36/ /application/php
   cp php.ini-production /application/php/lib/php.ini
   cd /application/php/etc/
   cp php-fpm.conf.default php-fpm.conf
   /application/php/sbin/php-fpm 启动php-fpm
   ps -ef |grep php-fpm
   lsof -i:9000
   说明：

   1. --with-mysql=/application/mysql mysql的安装位置
   2. --with-fpm-user=www nginx的用户
   3. --with-fpm-group=www nginx的组
   4. 按照上面的安装以后，测试nginx配合php解析没有问题，在php与mysql链接时，会出现500错误，通过一番努力得以解决：
   5. yum install php-mysql -y
   6. 编辑php.ini文件：修改前：mysqli.default_socket = 修改后：mysqli.default_socket =/tmp/mysql.sock cat /etc/my.cnf 查看mysql.sock的位置，寻找socket。
   7. 在编写linux与mysql链接的测试文件时，注意其编码格式！注意格式！注意格式！不要复制！不要复制！不要复制！：<?php$link=mysqlconnect("localhost", "root", "workjob");if ( $link ) {echo "success";}else{echo mysqlerror();}?>**
