zookeeper 开机启动197

第一种:直接修改/etc/rc.d/rc.local文件

在/etc/rc.d/rc.local文件中需要输入两行,其中export JAVA_HOME=/usr/java/jdk1.8.0_112是必须要有的,否则开机启动不成功,大家根据自己JDK安装的位置自行更改。另一行/usr/local/zookeeper-3.4.5/bin/zkServer.sh start则是我们zookeeper的启动命令。配置好之后,重启虚拟机,会发现已经可以开机自启了。

 
[root@zookeeper ~]# vim /etc/rc.d/rc.local
 
 
 
#!/bin/sh
 
#
 
# This script will be executed *after* all the other init scripts.
 
# You can put your own initialization stuff in here if you don't
 
# want to do the full Sys V style init stuff.
 
 
 
touch /var/lock/subsys/local
 
export JAVA_HOME=/usr/java/jdk1.8.0_112
 
/usr/local/zookeeper-3.4.5/bin/zkServer.sh start

第二种:把zookeeper做成服务

1、进入到/etc/rc.d/init.d目录下,新建一个zookeeper脚本

 
[root@zookeeper ~]# cd /etc/rc.d/init.d/
 
[root@zookeeper init.d]# pwd
 
/etc/rc.d/init.d
 
[root@zookeeper init.d]# touch zookeeper

2、给脚本添加执行权限

[root@zookeeper init.d]# chmod +x zookeeper

3、使用命令vim zookeeper进行编辑,在脚本中输入如下内容,其中同上面注意事项一样要添加export JAVA_HOME=//usr/java/jdk1.8.0_112这一行,否则无法正常启动。

 
[root@zookeeper init.d]# vim zookeeper
 
 
 
#!/bin/bash
 
#chkconfig:2345 20 90
 
#description:zookeeper
 
#processname:zookeeper
 
export JAVA_HOME=//usr/java/jdk1.8.0_112
 
case $1 in
 
start) su root /usr/local/zookeeper-3.4.5/bin/zkServer.sh start;;
 
stop) su root /usr/local/zookeeper-3.4.5/bin/zkServer.sh stop;;
 
status) su root /usr/local/zookeeper-3.4.5/bin/zkServer.sh status;;
 
restart) su /usr/local/zookeeper-3.4.5/bin/zkServer.sh restart;;
 
*) echo "require start|stop|status|restart" ;;
 
esac

4、使用service zookeeper start/stop命令来尝试启动关闭zookeeper,使用service zookeeper status查看zookeeper状态。

先来看启动及状态

 
[root@zookeeper init.d]# service zookeeper start
 
JMX enabled by default
 
Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg
 
Starting zookeeper ... STARTED
 
[root@zookeeper init.d]# service zookeeper status
 
JMX enabled by default
 
Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg
 
Mode: standalone
 
[root@zookeeper init.d]#

接着看关闭及状态

 
[root@zookeeper init.d]# service zookeeper stop
 
JMX enabled by default
 
Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg
 
Stopping zookeeper ... STOPPED
 
[root@zookeeper init.d]# service zookeeper status
 
JMX enabled by default
 
Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg
 
Error contacting service. It is probably not running.
 
[root@zookeeper init.d]#

5、添加到开机自启

[root@zookeeper init.d]# chkconfig --add zookeeper 

      添加完之后,我们使用chkconfig --list来查看开机自启的服务中是否已经有我们的zookeeper了,如下所示,可以看到在最后一行便是我们的zookeeper服务了。

 

       开机自启配置好了,我们重启一下试试,如下所示。一切正常!!说明我们的开机自启动成功了。

 
[root@zookeeper ~]# /usr/local/zookeeper-3.4.5/bin/zkServer.sh status
 
JMX enabled by default
 
Using config: /usr/local/zookeeper-3.4.5/bin/../conf/zoo.cfg
 
Mode: standalone
