Docker虛擬機經常使用命令

先更新軟件包
```
yum -y update
```
安裝Docker虛擬機
```
yum install -y docker
```

運行、重啓、關閉Docker虛擬機

service docker start
service docker start
service docker stop

搜索鏡像
```
docker search 鏡像名稱
```
下載鏡像
```
docker pull 鏡像名稱
```
查看鏡像
```
docker images
```
刪除鏡像
```
docker rmi 鏡像名稱
```
運行容器
```
docker run 啓動參數  鏡像名稱
```
查看容器列表
```
docker ps -a
```

中止、掛起、恢復容器

docker stop 容器ID
docker pause 容器ID
docker unpase 容器ID

查看容器信息
```
docker inspect 容器ID
```
刪除容器
```
docker rm 容器ID
```

數據卷管理

docker volume create 數據卷名稱  #建立數據卷
docker volume rm 數據卷名稱  #刪除數據卷
docker volume inspect 數據卷名稱  #查看數據卷

網絡管理

docker network ls 查看網絡信息
docker network create --subnet=網段 網絡名稱
docker network rm 網絡名稱

避免VM虛擬機掛起恢復以後，Docker虛擬機斷網
```
vi /etc/sysctl.conf
```
文件中添加net.ipv4.ip_forward=1這個配置html
```
#重啓網絡服務 systemctl restart network 
```

安裝PXC集羣，負載均衡，雙機熱備

安裝PXC鏡像

docker pull percona/percona-xtradb-cluster

爲PXC鏡像更名

docker tag percona/percona-xtradb-cluster pxc

建立net1網段

docker network create --subnet=172.18.0.0/16 net1

建立5個數據卷

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

建立備份數據卷（用於熱備份數據）
```
docker volume create --name backup
```

建立5節點的PXC集羣

注意，每一個MySQL容器建立以後，由於要執行PXC的初始化和加入集羣等工做，耐心等待1分鐘左右再用客戶端鏈接MySQL。另外，必須第1個MySQL節點啓動成功，用MySQL客戶端能鏈接上以後，再去建立其餘MySQL節點。前端

#建立第1個MySQL節點 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 #建立第2個MySQL節點 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 #建立第3個MySQL節點 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 #建立第4個MySQL節點 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 #建立第5個MySQL節點 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

安裝Haproxy鏡像
```
docker pull haproxy
```

宿主機上編寫Haproxy配置文件

vi /home/soft/haproxy.cfg

配置文件以下：vue

global
#工做目錄 chroot /usr/local/etc/haproxy #日誌文件，使用rsyslog服務中local5日誌設備（/var/log/local5），等級info log 127.0.0.1 local5 info #守護進程運行 daemon defaults log global mode  http #日誌格式 option  httplog #日誌中不記錄負載均衡的心跳檢測記錄 option  dontlognull  #鏈接超時（毫秒） timeout connect 5000  #客戶端超時（毫秒） timeout client 50000 #服務器超時（毫秒）  timeout server 50000 #監控界面 listen  admin_stats #監控界面的訪問的IP和端口 bind  0.0.0.0:8888 #訪問協議  mode  http #URI相對地址  stats uri /dbs #統計報告格式  stats realm Global\ statistics #登錄賬戶信息  stats auth admin:abc123456 #數據庫負載均衡 listen  proxy-mysql #訪問的IP和端口 bind  0.0.0.0:3306  #網絡協議 mode  tcp #負載均衡算法（輪詢算法） #輪詢算法：roundrobin #權重算法：static-rr #最少鏈接算法：leastconn #請求源IP算法：source  balance  roundrobin #日誌格式  option  tcplog #在MySQL中建立一個沒有權限的haproxy用戶，密碼爲空。Haproxy使用這個帳戶對MySQL數據庫心跳檢測。CREATE USER 'haproxy'@'%' IDENTIFIED BY '';  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檢測死鏈  option  tcpka

建立兩個Haproxy容器

#建立第1個Haproxy負載均衡服務器 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 #進入h1容器，啓動Haproxy docker exec -it h1 bash haproxy -f /usr/local/etc/haproxy/haproxy.cfg #建立第2個Haproxy負載均衡服務器 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 #進入h2容器，啓動Haproxy docker exec -it h2 bash haproxy -f /usr/local/etc/haproxy/haproxy.cfg

Haproxy容器內安裝Keepalived，設置虛擬IP

#進入h1容器 docker exec -it h1 bash #更新軟件包 apt-get update #安裝VIM apt-get install vim #安裝Keepalived apt-get install keepalived #編輯Keepalived配置文件（參考下方配置文件） vim /etc/keepalived/keepalived.conf #啓動Keepalived service keepalived start #宿主機執行ping命令 ping 172.18.0.201

配置文件內容以下：java

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
    }
}

#進入h2容器 docker exec -it h2 bash #更新軟件包 apt-get update #安裝VIM apt-get install vim #安裝Keepalived apt-get install keepalived #編輯Keepalived配置文件 vim /etc/keepalived/keepalived.conf #啓動Keepalived service keepalived start #宿主機執行ping命令 ping 172.18.0.201

    }
    virtual_ipaddress {
        172.18.0.201
    }
}

宿主機安裝Keepalived，實現雙擊熱備

#宿主機執行安裝Keepalived yum -y install keepalived #修改Keepalived配置文件 vi /etc/keepalived/keepalived.conf #啓動Keepalived service keepalived start

Keepalived配置文件以下：mysql

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
    }
}

}

熱備份數據

#進入node1容器 docker exec -it node1 bash #更新軟件包 apt-get update #安裝熱備工具 apt-get install percona-xtrabackup-24 #全量熱備 innobackupex --user=root --password=abc123456 /data/backup/full

冷還原數據
中止其他4個節點，並刪除節點

docker stop node2
docker stop node3
docker stop node4
docker stop node5
docker rm node2
docker rm node3
docker rm node4
docker rm node5

node1容器中刪除MySQL的數據nginx

#刪除數據 rm -rf /var/lib/mysql/* #清空事務 innobackupex --user=root --password=abc123456 --apply-back /data/backup/full/2018-04-15_05-09-07/ #還原數據 innobackupex --user=root --password=abc123456 --copy-back /data/backup/full/2018-04-15_05-09-07/
