官方源比较慢，改用国内镜像源：
阿里云
$ sudo yum-config-manager --add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

或：清华大学源
$ sudo yum-config-manager --add-repo \
https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

docker pull mysql:5.7
# 拉取zabbix/zabbix-java-gateway:centos-5.4-latest镜像
docker pull zabbix/zabbix-java-gateway:centos-5.4-latest
# 拉取zabbix/zabbix-server-mysql:centos-5.4-latest镜像
docker pull zabbix/zabbix-server-mysql:centos-5.4-latest
# 拉取zabbix/zabbix-web-nginx-mysql:centos-5.4-latest镜像
docker pull zabbix/zabbix-web-nginx-mysql:centos-5.4-latest

不要下载最新版本的mysql，不然后面server 无法在mysql上进行注册，会报 “MySQL server is not available. ” 错误

ip link set dev ens33 mtu 900 # centos7 貌似不生效，需要手动修改
docker network create --opt com.docker.network.driver.mtu=1400 --subnet 172.18.0.0/16 -d bridge  zabbix_net

以下配置，注意路径映射和密码修改

docker run --name mysql-server -dit \

      --restart=always \
    mysql:5.7 \
      --character-set-server=utf8 --collation-server=utf8_bin

#注：–restart=always写在-d mysql:5.7的前面，要不然容器启动后自动关闭。–restart=always跟随Docker启动

docker cp /data/MSYH.TTC 36:/usr/share/zabbix/assets/fonts/
docker exec -it -u root  zabbix-nginx /bin/bash
mv DejaVuSans.ttf DejaVuSans.ttf_bak
ln -s MSYH.TTC DejaVuSans.ttf

监控Zabbix Server

错误现象 Zabbix agent is not available (for 3m)

Get value from agent failed: cannot connect to [[127.0.0.1]:10050]: [111] Connection refused

默认安装好Zabbix之后自带一个监视本地系统的配置“Zabbix Server”,无法被检测到。

主要原因就是我们是将Zabbix服务器和Zabbix客户端都安装到了Docker上

解决方法：

打开配置-主机，接口那的ip为127.0.0.1，这个IP是宿主机的IP，需要修改为 zabbix-agent 容器的IP
