基础环境
cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)
docker安装
配置yum源
# vim /etc/yum.repos.d/docker-ce.repo
[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/7/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg
安装docker-ce
# wget https://mirrors.aliyun.com/centos-vault/7.3.1611/extras/x86_64/Packages/container-selinux-2.9-4.el7.noarch.rpm # yum localinstall container-selinux-2.9-4.el7.noarch.rpm -y # yum install docker-ce -y
更换源
顺便把docker源也换一下吧，免得一会还的重启
# vim /etc/docker/daemon.json { "registry-mirrors": ["https://registry.docker-cn.com"] }
启动docker，查看版本号
# systemctl start docker.service # docker version Client: Version: 18.09.0 API version: 1.39 Go version: go1.10.4 Git commit: 4d60db4 Built: Wed Nov 7 00:48:22 2018 OS/Arch: linux/amd64 Experimental: false Server: Docker Engine - Community Engine: Version: 18.09.0 API version: 1.39 (minimum version 1.12) Go version: go1.10.4 Git commit: 4d60db4 Built: Wed Nov 7 00:19:08 2018 OS/Arch: linux/amd64 Experimental: false
docker安装完毕！
开启网络转换
#echo 1 > /proc/sys/net/ipv4/ip_forward #网络重启会后要重新开启
用Dockerfile部署
zabbix-server部署阶段
要用docker跑zabbix-server，需要以下几个组件
| 组件名称 | 作用 |
|---|---|
| 数据库 | MySQL或是PostgreSQL |
| Zabbix Java gateway | Java管理扩展，可以不添加 |
| Zabbix server | zabbix 服务端 |
| zabbix-web | 与MySQL服务器实例和Zabbix server实例关联 |
| zabbix-agent | zabbix客户端 |
MySQL数据库
数据库我选择MySQL，还是得写Dockerfile，改一下时区，时间不对很麻烦，字符集也改一下吧
# mkdir /data/docker/mysql -p /data/docker/mysql]# vim Dockerfile FROM mysql:5.7 ENV LANG en_US.utf8 RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo Asia/Shanghai > /etc/timezone
构建镜像
#docker build -t debian-mysql5.7 .
# docker images

变量说明
| 变量 | |
|---|---|
| MYSQL_USER | 启动时要添加的用户 |
| MYSQL_DATABASE | 启动时要创建的数据库 |
| MYSQL_PASSWORD | 指定添加用的的密码 |
| MYSQL_ROOT_PASSWORD | root用户的密码 |
Zabbix Java gateway
这个看个人，如果不监控java应用服务器可以不安装这个，还是得写Dockerfile，改一下时区和编码。
/data/docker/java-gateway]# cat Dockerfile FROM zabbix/zabbix-java-gateway:latest ENV LANG en_US.utf8 RUN apk add -U tzdata RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo Asia/Shanghai > /etc/timezone /data/docker/java-gateway]# docker build -t zabbix-java-gateway . /data/docker/java-gateway]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE zabbix-java-gateway latest 7948dffa9af0 35 seconds ago 80.1MB
启动容器
需要映射一下10052端口
# docker run --hostname zabbix-java-gateway -name zabbix-java-gateway -t -p 10052:10052 -d zabbix-java-gateway 5e2434e7a4c6f3f947e6408ff5a90097e802c6a36282c36ce7e4cd5819474f7a # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5e2434e7a4c6 zabbix-java-gateway "docker-entrypoint.sh" 9 seconds ago Up 7 seconds 0.0.0.0:10052->10052/tcp zabbix-java-gateway 9a98a2ba0896 debian-mysql5.7 "docker-entrypoint.s…" 33 minutes ago Up 33 minutes 3306/tcp, 33060/tcp debian-mysql-5.7
Zabbix server
编写Dockerfile
/data/docker/zabbix-server]# cat Dockerfile FROM zabbix/zabbix-server-mysql:latest ENV LANG en_US.utf8 RUN apk add -U tzdata RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo Asia/Shanghai > /etc/timezone /data/docker/zabbix-server]# docker build -t zabbix-server . /data/docker/zabbix-server]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE zabbix-server latest 531aa3116f61 About a minute ago 62.3MB
需要映射10051端口，指定数据库服务器，连接MySQL和zabbix-java-gateway容器
10051:10051
--hostname zabbix-server
-e DB_SERVER_HOST="debian-mysql-5.7"
-e MYSQL_DATABASE="zabbix"

zabbix-web
编写Dockerfile
/data/docker/zabbix-web]# cat Dockerfile FROM zabbix/zabbix-web-nginx-mysql:latest ENV LANG en_US.utf8 RUN apk add -U tzdata RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo Asia/Shanghai > /etc/timezone /data/docker/zabbix-web]# docker build -t zabbix-web . /data/docker/zabbix-web]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE zabbix-web latest 6ff51e2f0545 About a minute ago 164MB
启动容器
需要映射80端口到宿主机，连接数据库，连接zabbix-server容器
# docker run --name zabbix-web -t -p 80:80 --hostname zabbix-web -e PHP_TZ="Asia/Shanghai" -e DB_SERVER_HOST="debian-mysql-5.7" -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="passwd" -e MYSQL_ROOT_PASSWORD="passwd" --link debian-mysql-5.7:mysql --link zabbix-server:zabbix-server -d zabbix-web f0c33f227992ce220730da9454df2f354565ed0b3d0813513a87797c2b752702 # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f0c33f227992 zabbix-web "docker-entrypoint.sh" 13 seconds ago Up 10 seconds 0.0.0.0:80->80/tcp, 443/tcp zabbix-web
以上方式安装的是最新版本，因为在指定镜像的时候没有指定版本号，默认的就是laster，也就是最新版本，建议zabbix-agent版本要和服务端一致。
看下安装的容器
# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b4b2524953b4 zabbix-web "docker-entrypoint.sh" About an hour ago Up About an hour 0.0.0.0:80->80/tcp, 443/tcp zabbix-web d5a45e58b69d zabbix-server "docker-entrypoint.sh" 2 hours ago Up 2 hours 0.0.0.0:10051->10051/tcp zabbix-server cd16d62b98c4 zabbix-java-gateway "docker-entrypoint.sh" 2 hours ago Up 2 hours 0.0.0.0:10052->10052/tcp zabbix-java-gateway 6a4b9ce12398 debian-mysql5.7 "docker-entrypoint.s…" 2 hours ago Up 2 hours 3306

访问：http://宿主机IP：80
zabbix-agent
安装（用官方yum源）
#rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm #yum -y install zabbix-agent-4.0.1
#vim /etc/zabbix/zabbix_agentd.conf Server=192.168.130.6 UnsafeUserParameters=1 Include=/etc/zabbix/zabbix_agentd.d/*.conf # systemctl start zabbix-agent
注意：如果要对宿主机进行监控，请编辑宿主机的zabbix_agentd.conf，将Server地址，默认127.0.0.1，修改为docker-server容器地址，否则不通；如果是对其他主机的监控则使用docker-zabbix-server宿主机的IP。
查看容器Zabbix-server的地址
# docker exec -it zabbix-server ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 23: eth0@if24: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP link/ether 02:42:ac:11:00:04 brd ff:ff:ff:ff:ff:ff inet 172.17.0.4/16 brd 172.17.255.255 scope global eth0 valid_lft forever preferred_lft forever
使用docker-compose
docker-compose去做，该镜像版本为4.0.1
安装docker-compose
# curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose # chmod +x /usr/local/bin/docker-compose # docker-compose --version docker-compose version 1.23.1, build b02f1306
编写zabbix.yml
这个已经是写好的，拿过去直接用吧，image不要动，其他的看自己情况自行调整吧
# mkdir /docker-compose # cd /docker-compose/
/docker-compose]# vim zabbix.yml version: '3' services: mysql: image: swr.cn-north-1.myhuaweicloud.com/rj-bai/zabbix-mysql environment: MYSQL_USER: zabbix MYSQL_DATABASE: zabbix MYSQL_PASSWORD: zabbix MYSQL_ROOT_PASSWORD: Sowhat? volumes: - /data/mysql/zabbix:/var/lib/mysql ports: - 3306:3306 restart: always networks: - zabbix zabbix-java-gateway: image: swr.cn-north-1.myhuaweicloud.com/rj-bai/zabbix-java-gateway ports: - 10052:10052 restart: always networks: - zabbix zabbix-server: image: swr.cn-north-1.myhuaweicloud.com/rj-bai/zabbix-server environment: DB_SERVER_HOST: mysql MYSQL_DATABASE: zabbix MYSQL_USER: zabbix MYSQL_PASSWORD: zabbix MYSQL_ROOT_PASSWORD: Sowhat? links: - mysql ports: - 10051:10051 depends_on: - mysql restart: always networks: - zabbix zabbix-web: image: swr.cn-north-1.myhuaweicloud.com/rj-bai/zabbix-web environment: PHP_TZ: Asia/Shanghai DB_SERVER_HOST: mysql MYSQL_DATABASE: zabbix MYSQL_USER: zabbix MYSQL_PASSWORD: zabbix MYSQL_ROOT_PASSWORD: Sowhat? links: - mysql ports: - 80:80 depends_on: - zabbix-server - mysql restart: always networks: - zabbix networks: zabbix: driver: bridge

访问：http://宿主机IP：80
网页端操作
直接编辑名为zabbix server的主机，Agent interfaces改为宿主机内网IP，然后update，我顺便又手动加了个主机进来，监控别的主机server地址直接写zabbix server宿主机即可。
邮件报警
以nginx down 为例前面博客有具体操作，这就不再赘述。
邮件设置
点开Administration→Media types→Email编辑，以使qq邮箱为例，163邮箱收不到。
添加收件人
接下来去Configuration→actions，选择Triggers，添加触发条件，可以有多个，我添加的是时间段和触发器。
在Acrion里添加动作—>operations
测试
手动停掉nginx

部署完成，有什么错误望指出，谢谢！
