Docker前后端分离应用部署命令总结

Docker虚拟机常用命令

  1. 先更新软件包

    yum -y update

  2. 安装Docker虚拟机

    yum install -y docker

  3. 运行、重启、关闭Docker虚拟机

    service docker start
service docker start
service docker stop

  4. 搜索镜像

    docker search 镜像名称

  5. 下载镜像

    docker pull 镜像名称

  6. 查看镜像

    docker images

  7. 删除镜像

    docker rmi 镜像名称

  8. 运行容器

    docker run 启动参数  镜像名称

  9. 查看容器列表

    docker ps -a

  10. 停止、挂起、恢复容器

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

  11. 查看容器信息

    docker inspect 容器ID

  12. 删除容器

    docker rm 容器ID

  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

  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

  15. 避免VM虚拟机挂起恢复之后，Docker虚拟机断网

    vi /etc/sysctl.conf
文件中添加`net.ipv4.ip_forward=1`这个配置
​```shell
#重启网络服务
systemctl  restart network
​```

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

  2. 为PXC镜像改名

    docker tag percona/percona-xtradb-cluster pxc

  3. 创建net1网段

    docker network create --subnet=172.18.0.0/16 net1

  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

  5. 创建备份数据卷（用于热备份数据）

    docker volume create --name backup
  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

  1. 安装Haproxy镜像

    docker pull haproxy

  2. 宿主机上编写Haproxy配置文件

    vi /home/soft/haproxy.cfg

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
    daemon
defaults
    log    global
    mode    http
    #日志格式
    option    httplog
    #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）
    timeout connect 5000
    #客户端超时（毫秒）
    timeout client  50000
    #服务器超时（毫秒）
    timeout server  50000
#监控界面
listen  admin_stats
    #监控界面的访问的IP和端口
    bind  0.0.0.0:8888
    #访问协议
    mode        http
    #URI相对地址
    stats uri   /dbs
    #统计报告格式
    stats realm     Global\ statistics
    #登陆帐户信息
    stats auth  admin:abc123456
#数据库负载均衡
listen  proxy-mysql
    #访问的IP和端口
    bind  0.0.0.0:3306
    #网络协议
    mode  tcp
    #负载均衡算法（轮询算法）
    #轮询算法：roundrobin
    #权重算法：static-rr
    #最少连接算法：leastconn
    #请求源IP算法：source
    balance  roundrobin
    #日志格式
    option  tcplog
    #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

  1. 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

  2. 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
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
    }
}
#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
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
    }
}

  1. 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
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 {
    delay_loop 3
    lb_algo rr
    lb_kind NAT
    persistence_timeout 50
    protocol TCP
    real_server 172.18.0.201 3306 {
        weight 1
    }
}

  1. 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

  2. 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
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/
