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. 安装其他依赖以其他包
    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.安装其他软件
    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 \
    --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 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. 按照上面的安装之后，测试nginx配合php解析没有问题，在php与mysql连接时，会出现500错误，经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连接的测试文件时，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！：
      $link=mysqlconnect("localhost", "root", "workjob");
      if ( $link ) {
      echo "success";
      }
      else{
      echo mysqlerror();
      }
      ?>**
