写个脚本

启动zookeeper 为例

脚本

  1 
  2 #!/bin/bash
  3 #description:开机自启脚本
  4 # 开机启动zookeeper
  5 /usr/local/services/zookeeper/zookeeper-3.4.14/bin/zkServer.sh start

设置运行权限&执行,可以看到zookeeper已经运行,说明脚本正常

[root@localhost myScrip]# chmod -R 777 zookeeper-scrip-start.sh    

[root@localhost myScrip]# ./zookeeper-scrip-start.sh 
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost myScrip]# /usr/local/services/zookeeper/zookeeper-3.4.14/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: standalone

添加开启启动

进入/etc/rc.d/ 修改rc.local 添加脚本执行的绝对路径/home/myScrip/zookeeper-scrip-start.sh


[root@localhost myScrip]# cd /etc/rc.d/
[root@localhost rc.d]# ls
init.d  rc0.d  rc1.d  rc2.d  rc3.d  rc4.d  rc5.d  rc6.d  rc.local
[root@localhost rc.d]# vim rc.local 
  1 #!/bin/bash
  2 # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
  3 #
  4 # It is highly advisable to create own systemd services or udev rules
  5 # to run scripts during boot instead of using this file.
  6 #
  7 # In contrast to previous versions due to parallel execution during boot
  8 # this script will NOT be run after all other services.
  9 #
 10 # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
 11 # that this script will be executed during boot.
 12 
 13 touch /var/lock/subsys/local
 14 
 15 /home/myScrip/zookeeper-scrip-start.sh

重启系统 reboot

发现没有成功,发现是rc.local权限不够
添加权限 chmod +x /etc/rc.d/rc.local
重启后查看到zookeeper已经运行

[root@localhost rc.d]# chmod +x /etc/rc.d/rc.local
[root@localhost rc.d]# ll
