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。
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

#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

#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

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

#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 {

interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 123456
}

}
}
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

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 {
