Centos7 安裝php-5.6.36

1. 相關依賴包的檢查與安裝
   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. 安裝其餘依賴以其餘包
   cd /home/oldboy/tools/
   wget https://ftp.gnu.org/gnu/libiconv/libiconv-1.14.tar.gz #下載安裝包 ,yum源中沒有
   tar zxvf libiconv-1.14.tar.gz #解壓
   ./configure --prefix=/usr/local/libconv
   make
   make install

   安裝libiconv軟件時，可能會報錯：*gets未聲明，不在函數內等*

   解決方法：cd /usr/local/libiconv/srclib
   sed -i -e '/gets is a security/d' ./stdio.in.h
   3.安裝其餘軟件
   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 上傳php-5.6.36.tar.gz
   5.解壓：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 \
   --with-iconv-dir=/usr/local/libiconv \
   --with-freetype-dir \
   --with-jpeg-dir \
   --with-png-dir \
   --with-zlib \
   --with-libxml-dir=/usr/ \
   --enable-xml \
   --disable-rpath \
   --enable-bcmath \
   --enable-shmop \
   --enable-sysvsem \
   --enable-inline-optimization \
   --with-curl \
   --enable-mbregex \
   --enable-fpm \
   --enable-mbstring \
   --with-mcrypt \
   --with-gd \
   --enable-gd-native-ttf \
   --with-openssl \
   --with-mhash \
   --enable-pcntl \
   --enable-sockets \
   --with-xmlrpc \
   --enable-soap \
   --enable-short-tags \
   --enable-static \
   --with-xsl \
   --with-fpm-user=www \
   --with-fpm-group=www \
   --enable-ftp \
   --enable-opcache=no
   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 啓動php-fpm
   ps -ef |grep php-fpm
   lsof -i:9000
   說明：

   1. --with-mysql=/application/mysql mysql的安裝位置
   2. --with-fpm-user=www nginx的用戶
   3. --with-fpm-group=www nginx的組
   4. 按照上面的安裝以後，測試nginx配合php解析沒有問題，在php與mysql鏈接時，會出現500錯誤，通過一番努力得以解決：
   5. yum install php-mysql -y
   6. 編輯php.ini文件：修改前：mysqli.default_socket = 修改後：mysqli.default_socket =/tmp/mysql.sock cat /etc/my.cnf 查看mysql.sock的位置，尋找socket。
   7. 在編寫linux與mysql鏈接的測試文件時，注意其編碼格式！注意格式！注意格式！不要複製！不要複製！不要複製！：<?php$link=mysqlconnect("localhost", "root", "workjob");if ( $link ) {echo "success";}else{echo mysqlerror();}?>**
