swarm docker-compose.yml NFS 搭建LNMP

列表：

172.16.0.40     （swarm-master）

172.16.0.160     (swarm-worker)

172.16.0.170     (swarm-worker)

172.16.0.30    (mariadb-master)

172.16.0.43     (mariadb-slave)

172.16.0.199   ( registry)

docker仓库搭建----registry

mkdir /registry/date  && chmod -r 777  /registry/date

pull && run

docker run -d -p 5000:5000 --name registry -v /registry/date:/var/lib/registry   --restart=always  registry

SWARM 集群搭建：

docker 开启远程连接：

echo "OPTIONS='-H 0.0.0.0:2377 -H unix:///var/run/docker.sock" > /etc/default/docker  && systemctl daemon-reload && systemctl restart docker 

docker 添加私有仓库：

 sudo mkdir -p /etc/docker && sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["172.16.0.199:5000"] } EOF

另一种方法:

vim /lib/systemd/system/docker.service

--insecure-registry 172.16.0.199:5000

检查： docker info

开启iptables  端口 :   tcp/2377      tcp/udp  4789 946 :所有节点 

 iptables -I INPUT -p tcp --dport 2377 ACCEPT

 iptables -I INPUT -p tcp --dport  7946 ACCEPT

 iptables -I INPUT -p tcp --dport  4789  ACCEPT　　

iptables -A INPUT -p udp --destination-port 7946 -j ACCEPT

iptables -A INPUT -p udp --destination-port 4789 ACCEPT

 

master 节点(40)  创建集群

docker swarm init --advertise-addr 172.16.0.40

在次查看 docker swarm join-token worker | docker swarm join-token manager

master 节点安装nfs

yum install nfs-utils -y && echo "/data/www 172.16.0.0/24(rw,sync,no_root_squash) " > /etc/export && systemctl start nfs

worker (160,170)加入集群

各项命令查看:

docker node ls   #查看node 节点

docker  network ls  #查看swarm-overlay 详情

docker volume ls    #查看数据卷

docker network inspect   (project_name)  #查看项目挂载网络

docker network volume   (project_name)  #查看项目挂载数据卷

docker service ps  (project_name)   #查看各container  详情
