开放端口，如果是做实验，就先在云安全策略组，全部开发吧。也可以有选择的开放对应的端口，用什么就开放什么。

1．查看当前centos版本

yum install -y redhat-lsb

lsb_release –a

2．按照docker要求系统为64位，系统内核版本为3.10以上

uname –r

查看是否已安装


docker


列表

yum list installed |





grep





docker

3．    安装docker:

yum -y install docker

4．    启动docker:

systemctl start docker

5．    查看服务是否启动：

systemctl status docker

6．阿里云镜像加速

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://01sy6s7g.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

systemctl status docker

7.设置开机自动启动命令：

systemctl enable docker.service

安装dubbo-admin

docker search dubbo-admin

docker pull chenchuxin/dubbo-admin

安装zookeeper

docker search zookeeper \

docker pull zookeeper:latest

第一步：创建ZooKeeper 挂载目录（数据挂载目录、配置挂载目录和日志挂载目录）

mkdir -p /usr/local/zookeeper/data # 数据挂载目录 
mkdir -p /usr/local/zookeeper/conf # 配置挂载目录 
mkdir -p /usr/local/zookeeper/logs # 日志挂载目录

第二步：添加ZooKeeper配置文件，在挂载配置文件目录(/usr/local/zookeeper/conf)下，新增 zoo.cfg 配置文件，配置内容如下：

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMet
ricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true 

第三步启动zookeeper:

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

查看zookeeper容器地地址

docker inspect zookeeper

启动dubbo-admin：

docker run -d  --name dubbo-admin  -v /home/dubbo/dubbo-admin:/data  -p 8180:8080  -e DUBBO_REGISTRY="zookeeper://172.17.0.2:2181"  -e DUBBO_ROOT_PASSWORD=root  -e DUBBO_GUEST_PASSWORD=guest  --restart=always  chenchuxin/dubbo-admin

# 注意 -e DUBBO_REGISTRY=zookeeper://ip:port 填写自己的zookeeper ip和端口号

# -e DUBBO_ROOT_PASSWORD 配置控制台root账号 密码

# -e DUBBO_GUEST_PASSWORD 配置控制台guest账号 密码

#-v 是宿主机与容器的挂载目录 #-p 是访问的端口号

运行：用户名 root/root或guest/guest
