Linux服务名重命名
最近发现telnet的服务xinetd名字不好记,应该重命名成telnetd(Linux很多这样的服务vsftpd,ntpd,mysqld等)
找到xinetd的启动脚本,复制成telnetd
[root@RHEL6 /etc/init.d]$cp xinetd telnetd
加入启动列表
[root@RHEL6 /etc/init.d]$ chkconfig --add telnetd
加入成功与否
[root@RHEL6 /etc/init.d]$chkconfig --list |grep telnetd
telnetd 0:off 1:off 2:off 3:on 4:on 5:on 6:off
测试
[root@RHEL6 /etc/init.d]$service telnetd status
xinetd (pid 3904) is running...
[root@RHEL6 /etc/init.d]$service telnetd stop
Stopping xinetd: [ OK ]
[root@RHEL6 /etc/init.d]$service telnetd start
Starting xinetd: [ OK ]
[root@RHEL6 /etc/init.d]$service telnetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
OK!
以上也仅仅是个人爱好,就当alias了一把,这其实也就是换了个名字而已,实际还是对服务xinetd进程操作!
不影响原服务
[root@RHEL6 /etc/init.d]$/etc/init.d/xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
[root@RHEL6 /etc/init.d]$service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
其他参数
[root@RHEL6 /root]$/etc/rc.d/init.d/xinetd
Usage: /etc/rc.d/init.d/xinetd {start|stop|status|restart|condrestart|reload}
start： 启动这个服务。
stop： 停止这个服务。
restart：先停止，再启动，也就是重新启动的意思。
reload： 重新加载设定档，这个参数只有在服务已经启动的状况下才能使用。
condrestart：有条件的重新启动，这个服务必须是已经启动的，才会被重新启动；如果这个服务尚未启动，则无须启动之。
[root@RHEL6 /root]$/etc/rc.d/init.d/telnetd stop
Stopping xinetd: [ OK ]
[root@RHEL6 /root]$/etc/rc.d/init.d/telnetd condrestart
[root@RHEL6 /root]$/etc/rc.d/init.d/telnetd status
xinetd is stopped
status：察看目前服务的启动状态。
具体详见服务启动脚本
