rancher 管理容器集群部署

所有节点同时执行安装，docker版本18.0，mariadb10.0，

1.时间同步

yum -y install ntp
yum update -y
/bin/systemctl start ntpd.service
ntpdate -s time.nist.gov;hwclock -w --localtime */10 * * * * ntpdate -s time.nist.gov;hwclock -w --localtime
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
cat >>/etc/sysconfig/clock < 
2.准备工作防火墙启动
 
yum -y install epel*
yum -y install wget htop iftop  unzip net-tools
systemctl start  firewalld  
systemctl enable firewalld  
firewall-cmd --state
firewall-cmd  --zone=public --add-port=10050-10051/udp --permanent
firewall-cmd  --zone=public --add-port=10050-10051/tcp --permanent
firewall-cmd  --zone=public --add-port=22-50000/tcp --permanent
firewall-cmd  --reload

在不同的节点上执行下面命令
hostnamectl set-hostname master
hostnamectl set-hostname node1
hostnamectl set-hostname node2

cat >>/etc/hosts < 
3.docker安装
 
yum install -y yum-utils device-mapper-persistent-data lvm2 wget
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum -y install docker-ce-18.06.1.ce-3.el7
docker --version
mkdir /etc/docker
cat > /etc/docker/daemon.json << EOF
 {
"registry-mirrors": ["https://jo6348gu.mirror.aliyuncs.com"]
 }
EOF
systemctl enable docker && systemctl start docker
 
rancher管理端操作
 
4.创建rancher/server服务端
 
docker pull mariadb:10.0   
docker run --name mariadb -p 13306:3306 -e MYSQL_ROOT_PASSWORD=nihaoma -d d1bde56970c6
docker exec -it mariadb bash
mysql -u root -pnihaoma
mysql
> CREATE DATAbase IF NOT EXISTS cattle COLLATE = 'utf8_general_ci' CHARACTER SET = 'utf8';
> GRANT ALL ON cattle.* TO 'tvb9ring'@'%' IDENTIFIED BY 'tvb9ring';
> GRANT ALL ON cattle.* TO 'tvb9ring'@'localhost' IDENTIFIED BY 'tvb9ring';
> FLUSH PRIVILEGES;
exit
exit

docker run -d --restart=always -p 18080:8080 --name rancher rancher/server:stable --db-host 10.100.10.190 --db-port 13306 --db-user tvb9ring --db-pass tvb9ring --db-name cattle
 
node1，node2上操作
 
5.加入rancher集群操作，先rancher管理界面设置密码获取秘钥
 
http://10.100.10.190:18080
 
 
 
 
 
添加节点主机
 
 
 
 
 node1上执行
 
[root@node1 ~]# sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.11 http://10.100.10.190:18080/v1/scripts/1C27D070EF76E020057C:1609372800000:Ug2pO4gg1MVUMMfj71QsGYqdsY
