Docker虚拟机常用命令
1. 先更新软件包
yum -y update
复制代码2. 安装Docker虚拟机
yum install -y docker
复制代码3. 运行、重启、关闭Docker虚拟机
service docker start
service docker start
service docker stop
复制代码4. 搜索镜像
docker search 镜像名称
复制代码5. 下载镜像
docker pull 镜像名称
复制代码6. 查看镜像
docker images
复制代码7. 删除镜像
docker rmi 镜像名称
复制代码8. 运行容器
docker run 启动参数 镜像名称
复制代码9. 查看容器列表
docker ps -a
复制代码10. 停止、挂起、恢复容器
docker stop 容器ID
docker pause 容器ID
docker unpase 容器ID
复制代码11. 查看容器信息
docker inspect 容器ID
复制代码12. 删除容器
docker rm 容器ID
复制代码13. 数据卷管理
docker volume create 数据卷名称 #创建数据卷
docker volume rm 数据卷名称 #删除数据卷
docker volume inspect 数据卷名称 #查看数据卷
复制代码14. 网络管理
docker network ls 查看网络信息
docker network create --subnet=网段 网络名称
docker network rm 网络名称
复制代码15. 避免VM虚拟机挂起恢复之后，Docker虚拟机断网
vi /etc/sysctl.conf
复制代码文件中添加net.ipv4.ip_forward=1这个配置
#重启网络服务
systemctl restart network
复制代码安装PXC集群，负载均衡，双机热备
1. 安装PXC镜像
docker pull percona/percona-xtradb-cluster
复制代码2. 为PXC镜像改名
docker tag percona/percona-xtradb-cluster pxc
复制代码3. 创建net1网段
docker network create --subnet=172.18.0.0/16 net1
复制代码4. 创建5个数据卷
docker volume create --name v1
docker volume create --name v2
docker volume create --name v3
docker volume create --name v4
docker volume create --name v5
复制代码5. 创建备份数据卷（用于热备份数据）
docker volume create --name backup
复制代码6. 创建5节点的PXC集群
注意，每个MySQL容器创建之后，因为要执行PXC的初始化和加入集群等工作，耐心等待1分钟左右再用客户端连接MySQL。另外，必须第1个MySQL节点启动成功，用MySQL客户端能连接上之后，再去创建其他MySQL节点。
#创建第1个MySQL节点
docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -v v1:/var/lib/mysql -v backup:/data --privileged --name=node1 --net=net1 --ip 172.18.0.2 pxc
#创建第2个MySQL节点
docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v2:/var/lib/mysql -v backup:/data --privileged --name=node2 --net=net1 --ip 172.18.0.3 pxc
#创建第3个MySQL节点
docker run -d -p 3308:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v3:/var/lib/mysql --privileged --name=node3 --net=net1 --ip 172.18.0.4 pxc
#创建第4个MySQL节点
docker run -d -p 3309:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v4:/var/lib/mysql --privileged --name=node4 --net=net1 --ip 172.18.0.5 pxc
#创建第5个MySQL节点
docker run -d -p 3310:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v5:/var/lib/mysql -v backup:/data --privileged --name=node5 --net=net1 --ip 172.18.0.6 pxc
复制代码7. 安装Haproxy镜像
docker pull haproxy
复制代码8. 宿主机上编写Haproxy配置文件
vi /home/soft/haproxy.cfg
复制代码配置文件如下：
global
#工作目录
chroot /usr/local/etc/haproxy
#日志文件，使用rsyslog服务中local5日志设备（/var/log/local5），等级info
log 127.0.0.1 local5 info
#守护进程运行

#日志中不记录负载均衡的心跳检测记录
option dontlognull
#连接超时（毫秒）

#在MySQL中创建一个没有权限的haproxy用户，密码为空。Haproxy使用这个账户对MySQL数据库心跳检测
option mysql-check user haproxy
server MySQL_1 172.18.0.2:3306 check weight 1 maxconn 2000
server MySQL_2 172.18.0.3:3306 check weight 1 maxconn 2000
server MySQL_3 172.18.0.4:3306 check weight 1 maxconn 2000
server MySQL_4 172.18.0.5:3306 check weight 1 maxconn 2000
server MySQL_5 172.18.0.6:3306 check weight 1 maxconn 2000
#使用keepalive检测死链
option tcpka
复制代码9. 创建两个Haproxy容器
#创建第1个Haproxy负载均衡服务器
docker run -it -d -p 4001:8888 -p 4002:3306 -v /home/soft/haproxy:/usr/local/etc/haproxy --name h1 --privileged --net=net1 --ip 172.18.0.7 haproxy
#进入h1容器，启动Haproxy
docker exec -it h1 bash
haproxy -f /usr/local/etc/haproxy/haproxy.cfg
#创建第2个Haproxy负载均衡服务器
docker run -it -d -p 4003:8888 -p 4004:3306 -v /home/soft/haproxy:/usr/local/etc/haproxy --name h2 --privileged --net=net1 --ip 172.18.0.8 haproxy
#进入h2容器，启动Haproxy
docker exec -it h2 bash
haproxy -f /usr/local/etc/haproxy/haproxy.cfg
复制代码10. Haproxy容器内安装Keepalived，设置虚拟IP
#进入h1容器
docker exec -it h1 bash
#更新软件包
apt-get update
#安装VIM
apt-get install vim
#安装Keepalived
apt-get install keepalived
#编辑Keepalived配置文件（参考下方配置文件）
vim /etc/keepalived/keepalived.conf
#启动Keepalived
service keepalived start
#宿主机执行ping命令
ping 172.18.0.201
复制代码配置文件内容如下：
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 123456
}
virtual_ipaddress {
172.18.0.201
}
}
复制代码#进入h2容器
docker exec -it h2 bash
#更新软件包
apt-get update
#安装VIM
apt-get install vim
#安装Keepalived
apt-get install keepalived
#编辑Keepalived配置文件
vim /etc/keepalived/keepalived.conf
#启动Keepalived
service keepalived start
#宿主机执行ping命令
ping 172.18.0.201
复制代码配置文件内容如下：
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 123456
}
virtual_ipaddress {
172.18.0.201
}
}
复制代码11. 宿主机安装Keepalived，实现双击热备
#宿主机执行安装Keepalived
yum -y install keepalived
#修改Keepalived配置文件
vi /etc/keepalived/keepalived.conf
#启动Keepalived
service keepalived start
复制代码Keepalived配置文件如下：
vrrp_instance VI_1 {
state MASTER
interface ens33
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.99.150
}
}
virtual_server 192.168.99.150 8888 {
delay_loop 3
lb_algo rr
lb_kind NAT
persistence_timeout 50
protocol TCP
real_server 172.18.0.201 8888 {
weight 1
}
}
virtual_server 192.168.99.150 3306 {

lb_algo rr
lb_kind NAT
persistence_timeout 50
protocol TCP
real_server 172.18.0.201 3306 {

}
}
复制代码12. 热备份数据
#进入node1容器
docker exec -it node1 bash
#更新软件包
apt-get update
#安装热备工具
apt-get install percona-xtrabackup-24
#全量热备
innobackupex --user=root --password=abc123456 /data/backup/full
复制代码13. 冷还原数据
停止其余4个节点，并删除节点
docker stop node2
docker stop node3
docker stop node4
docker stop node5
docker rm node2
docker rm node3
docker rm node4
docker rm node5
复制代码node1容器中删除MySQL的数据
#删除数据
rm -rf /var/lib/mysql/*
#清空事务
innobackupex --user=root --password=abc123456 --apply-back /data/backup/full/2018-04-15_05-09-07/
#还原数据
innobackupex --user=root --password=abc123456 --copy-back /data/backup/full/2018-04-15_05-09-07/
