TP5 通过shell建立PHP守护程序

用 vim建立 /etc/init.d/keepalive文件

#!/bin/bash
# chkconfig: 2345 10 90
# description: Start and Stop KEEP_ALIVE

PHP="/usr/local/php/bin/php"

KEEP_ALIVE_LOG="${KEEP_ALIVE_DIV}/${KEEP_ALIVE_NAME}.log" #服务运行日志 记录错误信息

#判断程序是否已经在运行
status_script(){

• 把文件权限设成 755

• chmod 755 /etc/init.d/keepalive

• 设成开机启动

• chkconfig keepalive on

• 搞定 试一下

• service keepalive status
  
  service keepalive start
  
  service keepalive 
  
  service keepalive stop

如果你的将服务不稳定,可以把他加到计划任务定时重启 保证后端一直执行

dos2unix shell/keepalive.sh
