安装

1.下载Consul

[root@localhost 20190903]

wget https://releases.hashicorp.com/consul/0.9.3/consul_0.9.3_linux_amd64.zip

2.解压

[root@localhost 20190903]# unzip consul_0.9.3_linux_amd64.zip

3.验证是否安装consul成功

[root@localhost consul]# ./consul

出现如图所是则表示安装成功。

3.启动consul

-dev表示开发模式运行，另外还有-server表示服务模式运行

[root@localhost consul]# ./consul agent –dev

4.远程访问

[root@localhost consul]# ./consul agent -dev -client 192.168.126.139

在浏览器输入:http://192.168.126.139:8500/ui/

开机自动重启配置

1.在/etc/init.d/目录下创建consul

[root@localhost consul]# cd /etc/init.d/

[root@localhost init.d]#vi consul

Consul内容如下图所示：

具体脚本如下图所示：

#!/bin/sh
#chkconfig: - 85 15
#description: consul service
#author: fab
 

export JAVA_HOME=/usr/java/jdk1.8.0_211
export JAVA_BIN=/usr/java/jdk1.8.0_211/bin
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH

case "$1" in
start)
    cd /usr/local/consul
    ./consul agent -dev -client=192.168.126.139
!
    echo "consul startup"
    ;;  
stop)
    es_pid=`ps aux|grep consul | grep -v 'grep consul' | awk '{print $2}'`
    kill -9 $es_pid
    echo "consul stopped"
    ;;  
restart)
    es_pid=`ps aux|grep consul | grep -v 'grep consul' | awk '{print $2}'`
    kill -9 $es_pid
    echo "consul stopped"
	cd /usr/local/consul
    ./consul agent -dev -client=192.168.126.139
!
    echo "consul startup"
    ;;  
*)
    echo "start|stop|restart"
    ;;  
esac

exit $?

2.修改consul可执行权限

[root@localhost init.d]# chmod +x consul

3.添加consul到系统服务中

[root@localhost init.d]# chkconfig --add consul

4.设置consul服务为开机启动

[root@localhost init.d]# chkconfig consul on

5.开机启动测试

[root@localhost init.d]# reboot

[root@localhost init.d]# ps -elf|grep consul
