CentOS 6.5 开机启动MySQL Apache Nginx脚本

环境：CentOS 6.5 64bit

1.自己新建一个脚本

在这个脚本里写入自己开机时想执行的命令，如启动MySQL、Apache、Nginx等服务。

#!/bin/bash
/etc/init.d/mysqld start
service httpd start
/usr/local/nginx/sbin/nginx

2.给脚本添加可执行权限

[root@localhost ~]# ll stalker_server.sh
-rw-r--r-- 1 root root 86 Feb  2 14:43 stalker_server.sh

[root@localhost ~]# chmod +x stalker_server.sh

[root@localhost ~]# ll stalker_server.sh
-rwxr-xr-x 1 root root 86 Feb  2 14:43 stalker_server.sh

3.打开/etc/rc.d/rc.local文件，在最后面添加如下

[root@localhost ~]# ll /etc/rc.d/rc.local
-rwxr-xr-x 1 root root 250 Feb  2 14:52 /etc/rc.d/rc.local

[root@localhost ~]# vim /etc/rc.d/rc.local

/root/stalker_server.sh

这样stalker_server.sh这个脚本在开机的时候就会被执行了，以后新增启动服务就可以直接在这个脚本文件中增加启动服务的命令即可。

在CentOS 7，/etc/rc.d/rc.local的文件的执行权限没有了，开机的时候执行自己的脚本是不能启动服务的，需要执行下面的命令增加可执行权限。

chmod +x /etc/rc.d/rc.local

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In constrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
