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://"]
}
启动docker，查看版本号
# systemctl start docker.service
# docker version

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 |
|
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 \

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。

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

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

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

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:///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
