我们最终的目的是搭建如下的一个系统,由于自己画的源文件已经丢失,只能上传自己打印出来的图片,相信大家根据这个框架图就不难理解下面的命令了。

docker内修改的文件重启后 docker重新部署项目_redis


这里,我们以部署人人开源后端项目为例,来介绍docker项目的部署和运维,选择renren-fast下载相应的前后端代码。

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

#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

7 安装Haproxy镜像

docker pull haproxy

8 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。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检测死链
   option  tcpka

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

10 Haproxy容器内安装Keepalived,设置虚拟IP
进入容器1

#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
    }
}

进入容器2

#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(与h1的配置文件相同):

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
    }
}

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

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
    }
}

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

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

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/
