centos服务器重启脚本命令

在 CentOS 系统中，创建一个用于重启服务器的简单脚本通常会包含 `shutdown` 或 `reboot` 命令。这里是一个基本的重启脚本示例，可以保存到 `/etc/init.d/restart_server` 文件中（假设你需要设置定时重启，可以在 crontab 中运行它）：

#!/bin/bash
# chkconfig: 2345 90 10
# description: Restart Server Script

# Source function library in /etc/rc.d/init.d/functions
. /etc/rc.d/init.d/functions

# Check if root user is running the script
if [ "$(id -u)" != "0" ]; then
   echo "This script must be run as root."
   exit 1
fi

# Function to perform the actual reboot
restart_server() {
   local message="Restarting server at $(date +'%Y-%m-%d %H:%M:%S')"
   log_action_msg $message
   shutdown -r now
}

# Run the restart action if called directly or via service
case "$1" in
   start|stop|restart)
      restart_server
      ;;
   *)
      echo "Usage: /sbin/service restart_server {start|stop|restart}"
      exit 1
      ;;
esac

exit 0

要启用此服务并使其开机自启，可以运行以下命令：

chkconfig restart_server on
systemctl enable restart_server.service

然后你可以通过 `/sbin/service restart_server restart` 进行手动重启。
