搭建环境

192.168.0.111
192.168.0.112
192.168.0.113

拉取镜像

• 官网
• 3台分别执行

docker pull zookeeper

创建挂载文件

创建挂载的文件夹

3台分别执行

mkdir -p /usr/local/zookeeper/data
mkdir -p /usr/local/zookeeper/conf
mkdir -p /usr/local/zookeeper/logs
chmod 777 /usr/local/zookeeper/data
chmod 777 /usr/local/zookeeper/conf
chmod 777 /usr/local/zookeeper/conf

创建挂载的zoo.cfg

192.168.0.111

vim /usr/local/zookeeper/conf/zoo.cfg

tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data
dataLogDir=/datalog
clientPort=2181
maxClientCnxns=60
server.1=0.0.0.0:2888:3888
server.2=192.168.0.112:2888:3888
server.3=192.168.0.113:2888:3888

192.168.0.112

vim /usr/local/zookeeper/conf/zoo.cfg

tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data
dataLogDir=/datalog
clientPort=2181
maxClientCnxns=60
server.1=192.168.0.111:2888:3888
server.2=0.0.0.0:2888:3888
server.3=192.168.0.113:2888:3888

192.168.0.113

vim /usr/local/zookeeper/conf/zoo.cfg

tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data
dataLogDir=/datalog
clientPort=2181
maxClientCnxns=60
server.1=192.168.0.111:2888:3888
server.2=192.168.0.112:2888:3888
server.3=0.0.0.0:2888:3888

创建挂载的myid

192.168.0.111

vim /usr/local/zookeeper/data/myid

1

192.168.0.112

vim /usr/local/zookeeper/data/myid

2

192.168.0.113

vim /usr/local/zookeeper/data/myid

3

放行端口号

3台分别执行

firewall-cmd --zone=public --add-port=2181/tcp --permanent
firewall-cmd --zone=public --add-port=2888/tcp --permanent
firewall-cmd --zone=public --add-port=3888/tcp --permanent
firewall-cmd --reload

启动

3台分别执行

docker run --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 -d -v /usr/local/zookeeper/conf/zoo.cfg:/conf/zoo.cfg -v /usr/local/zookeeper/data:/data  -v /usr/local/zookeeper/logs:/datalog  --restart always --privileged=true zookeeper

• 查看状态

docker exec -it zookeeper zkServer.sh status

或者

yum -y install nc

echo stat|nc 127.0.0.1 2181
