这次给大家带来php-fpm服务启动脚本步骤详解，php-fpm服务启动脚本的注意事项有哪些，下面就是实战案例，一起来看一下。

先创建自启动文件：/etc/init.d/php-fpm

内容如下：

#! /bin/sh
### BEGIN INIT INFO
# Provides:     php-fpm
# Required-Start:  $remote_fs $network
# Required-Stop:   $remote_fs $network
# Default-Start:   2 3 4 5
# Default-Stop:   0 1 6
# Short-Description: starts php-fpm
# Description:    starts the PHP FastCGI Process Manager daemon
### END INIT INFO
prefix=/usr/local/php
exec_prefix=${prefix}
php_fpm_BIN=${exec_prefix}/sbin/php-fpm
php_fpm_CONF=${prefix}/etc/php-fpm.conf
php_fpm_PID=${prefix}/var/run/php-fpm.pid
php_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID"
wait_for_pid () {
  try=0
  while test $try -lt 35 ; do
    case "$1" in
      &#39;created&#39;)
      if [ -f "$2" ] ; then
        try=&#39;&#39;
        break
      fi
      ;;
      &#39;removed&#39;)
      if [ ! -f "$2" ] ; then
        try=&#39;&#39;
        break
      fi
      ;;
    esac
    echo -n .
    try=`expr $try + 1`
    sleep 1
  done
}
case "$1" in
  start)
    echo -n "Starting php-fpm "
    $php_fpm_BIN --daemonize $php_opts
    if [ "$?" != 0 ] ; then
      echo " failed"
      exit 1
    fi
    wait_for_pid created $php_fpm_PID
    if [ -n "$try" ] ; then
      echo " failed"
      exit 1
    else
      echo " done"
    fi
  ;;
  stop)
    echo -n "Gracefully shutting down php-fpm "
    if [ ! -r $php_fpm_PID ] ; then
      echo "warning, no pid file found - php-fpm is not running ?"
      exit 1
    fi
    kill -QUIT `cat $php_fpm_PID`
    wait_for_pid removed $php_fpm_PID
    if [ -n "$try" ] ; then
      echo " failed. Use force-quit"
      exit 1
    else
      echo " done"
    fi
  ;;
  status)
    if [ ! -r $php_fpm_PID ] ; then
      echo "php-fpm is stopped"
      exit 0
    fi
    PID=`cat $php_fpm_PID`
    if ps -p $PID | grep -q $PID; then
      echo "php-fpm (pid $PID) is running..."
    else
      echo "php-fpm dead but pid file exists"
    fi
  ;;
  force-quit)
    echo -n "Terminating php-fpm "
    if [ ! -r $php_fpm_PID ] ; then
      echo "warning, no pid file found - php-fpm is not running ?"
      exit 1
    fi
    kill -TERM `cat $php_fpm_PID`
    wait_for_pid removed $php_fpm_PID
    if [ -n "$try" ] ; then
      echo " failed"
      exit 1
    else
      echo " done"
    fi
  ;;
  restart)
    $0 stop
    $0 start
  ;;
  reload)
    echo -n "Reload service php-fpm "
    if [ ! -r $php_fpm_PID ] ; then
      echo "warning, no pid file found - php-fpm is not running ?"
      exit 1
    fi
    kill -USR2 `cat $php_fpm_PID`
    echo " done"
  ;;
  *)
    echo "Usage: $0 {start|stop|force-quit|restart|reload|status}"
    exit 1
  ;;
esac

配置php-fpm服务

# 设置权限
chmod 755 /etc/init.d/php-fpm
# php-fpm加入服务
chkconfig --add php-fpm
# php-fpm 234级别下设置为启动
chkconfig php-fpm on
# 查看php-fpm服务当前配置
chkconfig --list php-fpm
php-fpm     0:off  1:off  2:on  3:on  4:on  5:on  6:off

php-fpm使用方法

脚本说明

# Source function library. 
. /etc/rc.d/init.d/functions 
# Source networking configuration. 
. /etc/sysconfig/network

Copy after login

以上量行代码有人会疑问他们到底是做什么的，'.'是source类似于程序中的include和require,将functions里面的方法全部倒入到这边，这边程序便可以使用，例如这边用到的daemon、status。第二行的network实际上就几行，如下

NETWORKING=yes
HOSTNAME=E10162

Copy after login

将他们作为变量赋值,判断网卡是否启动，如果你的nginx不走网卡，其实网络这段可以去掉.
