基于docker部署zabbix

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

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
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

启动容器

# docker run --hostname mysql --name debian-mysql-5.7 -t \
 -e MYSQL_USER="zabbix" \
 -e MYSQL_DATABASE="zabbix" \
 -e MYSQL_PASSWORD="passwd" \
 -e MYSQL_ROOT_PASSWORD="passwd" \

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

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

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" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="passwd" \
-e MYSQL_ROOT_PASSWORD="passwd" \
-e ZBX_JAVAGATEWAY="zabbix-java-gateway" \
--link debian-mysql-5.7:mysql \
--link zabbix-java-gateway:zabbix-java-gateway \
-d zabbix-server
# docker ps

a45ef352cc68 zabbix-server "docker-entrypoint.sh" 9 minutes ago Up 8 minutes 0.0.0.0:10051->10051/tcp zabbix-server

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

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_USER="zabbix" \

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

/tcp, 33060/tcp           debian-mysql-5.

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

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！
