2)安装 libmcrypt mhash mcrypt

注：mcrypt依赖前二者

wget "http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz"
wget "http://downloads.sourceforge.net/mhash/mhash-0.9.9.9.tar.gz"
wget "https://sourceforge.net/projects/mcrypt/files/MCrypt/2.6.8/mcrypt-2.6.8.tar.gz"

注：configure: error: * libmcrypt was not found

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

或者
ldconfig

3)编译安装PHP7

说明：PHP7 移除了已经被废弃的函数，如 mysql_ 系列函数在 PHP5.5 被废弃，在 PHP7被删除，而且 php-fpm 也已经被 php 归入，直接在选项中开启便可，--enable-cgi 是默认配置且 --enable-fast-cgi 已经被废除，--enable-cgi 便可让 fpm 模式调用。

ladp在64的系统里可能存在写库关联问题，执行下面的命令
cp -frp /usr/lib64/libldap* /usr/lib/

• --enable-cgi --disable-cgi :
  在5.3.0后 enable-cgi 等同于--enable-fastcgi 也就是说此后不须要在额外声明 --enable-fastcgi，且 --enable-force-cgi-redirect 也默认有效且被废弃在编译选项中，要禁用需修改php.ini的cgi.force_redirect为0

• --with-apxs2 --with-apache：
  --with-apxs2是直接把php编译到apache的模块中去 --with-apache是置顶apache的serverRoot路径，生成apache的php模块 修改apache配置文件手动加载：
  AddType application/x-httpd-php .php .html .htm

• php7.0废除了--with-mysql编译选项，且推荐使用mysqlnd驱动

• -bash: --with-openssl: command not found：
  which openssl 查看目录 添加环境变量
  export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

4)php-fpm 服务脚本

#! /bin/sh
# Comments to support chkconfig on CentOS
# chkconfig: 2345 65 37
#
set -e

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="php-fpm daemon"
NAME=php-fpm

#php-fpm命令的路径
DAEMON=/usr/local/php/sbin/$NAME

#php-fpm的配置文件
CONFIGFILE=/usr/local/php/etc/php-fpm.conf

#php-fpm的pid文件
PIDFILE=/usr/local/php/var/run/$NAME.pid

SCRIPTNAME=/etc/init.d/$NAME

# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0
d_start() { 
    $DAEMON -y $CONFIGFILE || echo -n " already running"
}

d_stop() {
     kill -QUIT `cat $PIDFILE` || echo -n " not running"
}

d_reload() { 
    kill -HUP `cat $PIDFILE` || echo -n " can't reload"
}

case "$1" in 
  start) 
          echo -n "Starting $DESC is success" 
          d_start 
          echo "." ;; 
  stop) 
          echo -n "Stopping $DESC is success" 
          d_stop 
          echo "." ;; 
  reload) 
          echo -n "Reloading $DESC configuration..." 
          d_reload 
          echo "reloaded." ;; 
    restart) 
          echo -n "Restarting $DESC is success" 
          d_stop 
          sleep 1 
          d_start 
          echo "." ;; 
    *) 
          echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2 
          exit 3 ;;
esac

内置php-fpm

cd /usr/local/php7/etc
mv php-fpm.conf.default php-fpm.conf
mv php-fpm.d/www.conf.default php-fpm.d/www.conf

#进入源码安装包目录
cd /data/php-7.0.11

#copy php配置文件 获得php.ini 配置这里不做说明      
cp php.ini-production /usr/local/php/etc/php.ini  
cd sapi/fpm              #进到源码包里的sapi/fpm目录
cp init.d.php-fpm /etc/init.d/php-fpm      #copy cgi管理器 获得php-fpm
chmod +x /etc/init.d/php-fpm               #附上可执行权限
chkconfig --add php-fpm                    #加入开机启动项
chkconfig php-fpm on
service php-fpm start                      #启动php-fpm
ps -ef | grep php-fpm                      #查看php-fpm启动状态
