centos开机启动
开机启动方式有三种:
-
@H_502_5@把启动程序的命令添加到/etc/rc.d/rc.local文件中,rc.local是在完成所有初始化之后执行的,所以在这里做手脚很合适
@H_502_5@把写好的启动脚本添加到目录/etc/rc.d/init.d/,然后使用命令chkconfig设置开机启动。
@H_502_5@把启动程序的命令添加到/etc/rc.d/rc.sysinit 文件中(慎用,防止系统启动不了)
chkconfig命令
chkconfig –list命令:查看开机启动的清单列表
chkconfig xxx on :设置开机启动
[root@localhost ~]@H_502_23@# chkconfig MysqLd on
要取消掉某个服务自动启动,只需要将最后的参数 “on” 变更为 “off” 即可
[root@localhost ~]@H_502_23@# chkconfig MysqLd off
[root@localhost ~]@H_502_23@# chkconfig –-add postfix
查看所有自动启动的服务
[root@localhost init.d]@H_502_23@# chkconfig --list

说明:如果0~6均为off,则说明服务不会在系统启动的时候自动启动。输入:chkconfig smb on 即可启动
修改 /etc/rc.d/rc.local 这个文件
例如将 apache、MysqL、samba、svn 等这些服务的开机自启动问题一起搞定
vim /etc/rc.d/rc.local
#添加以下命令
/usr/sbin/apachectl start
/etc/rc.d/init.d/MysqLd start
/etc/rc.d/init.d/smb start
/usr/local/subversion/bin/svnserve -d
service 服务
当我们输入service命令时,linux会去/etc/rc.d/init.d下去找这个脚本运行
/etc/rc.d/init.d和/etc/init.d 联系区别
[root@webtest ~]# ls -ld /etc/rc.d
drwxr-xr-x. 10 root root 4096 Jun 21 16:48 /etc/rc.d
[root@webtest ~]# ls -ld /etc/init.d
lrwxrwxrwx. 1 root root 11 Jun 21 16:48 /etc/init.d -> rc.d/init.d
