拉取镜像，我们选择docker.io/mariadb ：
[root@10e131e69e15 fanzhang]# docker pull docker.io/mariadb
Using default tag: latest
Trying to pull repository docker.io/library/mariadb ...

docker.io/mariadb latest 13814daf85b2 hours ago 403.3 MB
在目录/root/fanzhang/docker/mysql下创建目录conf/，data/，logs/分别用于映射配置文件、数据和日志，然后运行容器，使用mariadb镜像：
[root@10e131e69e15 fanzhang]# docker run -p : --name f-mysql -v /root/fanzhang/docker/mysql/conf:/etc/mysql/conf.d -v /root/fanzhang/docker/mysql/logs:/logs -v /root/fanzhang/docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD= -d mariadb:latest

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e7185734f25f mariadb:latest "docker-entrypoint.sh" About a minute ago Up About a minute 0.0.0.0:->/tcp f-mysql
数据库已经准备就绪，可以继续在8.15上安装zabbix server了。
二、docker安装zabbix server
安装zabbix-server-mysql——
拉取镜像：
[root@10e131e69e15 fanzhang]# docker pull docker.io/zabbix/zabbix-server-mysql
Using default tag: latest
Trying to pull repository docker.io/zabbix/zabbix-server-mysql ...

使用镜像运行容器：
[root@10e131e69e15 fanzhang]# docker run --name f-zabbix-server -p : --net=host -e DB_SERVER_HOST="172.28.8.15" -e DB_SERVER_PORT= -e MYSQL_USER="root" -e MYSQL_PASSWORD="" -d docker.io/zabbix/zabbix-server-mysql
7b9d1d8d81924c0734821938bc766d3f3e3f2d70440a1e3c3cecced7746f7279
安装zabbix-web-apache-mysql——
拉取镜像：
[root@10e131e69e15 fanzhang]# docker pull docker.io/zabbix/zabbix-web-apache-mysql
Using default tag: latest
Trying to pull repository docker.io/zabbix/zabbix-web-apache-mysql ...

使用镜像运行容器（注意，-p 将容器的80端口映射到宿主机的8088端口）：
[root@10e131e69e15 fanzhang]# docker run --name f-zabbix-web-apache-mysql -p : -e DB_SERVER_HOST="172.28.8.15" -e DB_SERVER_PORT= -e MYSQL_USER="root" -e MYSQL_PASSWORD="" -e ZBX_SERVER_HOST="172.28.8.15" -e TZ="Asia/Shanghai" -d zabbix/zabbix-web-apache-mysql
393df8ea3865a415aedcbcad4163f80f3baae828f0f29f08b3a515e51d382177
在8.15上打开防火墙的8088端口：
iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport -j ACCEPT
启动报错，可以通过docker logs <container_name>检查。
zabbix-server-mysql、zabbix-web-apache-mysql启动后，尝试：
[root@10e131e69e15 fanzhang]# curl 172.28.8.15:

setTimeout('document.location.reload();', );
手动创建zabbix数据库，尝试curl：
[root@10e131e69e15 fanzhang]# curl 172.28.8.15:
<!DOCTYPE html>

<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>

setTimeout('document.location.reload();', );
进入容器检查数据库连接：
[root@10e131e69e15 zabbix]# docker ps --all
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

可以看到，其实是可以连接数据库的，那么问题出在哪里呢？
还是依次检查一下启动的两个zabbix相关的容器，看下其日志：
[root@10e131e69e15 fanzhang]# docker logs f-zabbix-server
** Deploying Zabbix server with mysql database
** Preparing the system
** Preparing Zabbix server
********************
* DB_SERVER_HOST: 172.28.8.15
* DB_SERVER_PORT:
* DB_SERVER_DBNAME: zabbix
* DB_SERVER_ZBX_USER: “root -e MYSQL_PASSWORD=“
* DB_SERVER_ZBX_PASS: zabbix
********************
mysqladmin: unknown option '-e'
**** MySQL server is not available. Waiting seconds…
可以发现，user的配置并不正确，应该是中文字符的锅。删除这个容器，重新启动。
[root@10e131e69e15 fanzhang]# docker run --name f-zabbix-server -p : --net=host -e DB_SERVER_HOST="172.28.8.15" -e DB_SERVER_PORT= -e MYSQL_USER="root" -e MYSQL_PASSWORD="" -d docker.io/zabbix/zabbix-server-mysql

[root@10e131e69e15 fanzhang]# docker logs f-zabbix-server

********************
* DB_SERVER_HOST: 172.28.8.15

* DB_SERVER_ZBX_USER: root
* DB_SERVER_ZBX_PASS:
********************
** Creating 'root' user in MySQL database
** Database 'zabbix' already exists. Please be careful with database COLLATE!
** Creating 'zabbix' schema in MySQ
这次应该是没问题了。
我们再看下f-zabbix-web-apache-mysql的日志，一切正常。
三、vm内部安装zabbix agent
尝试使用直接在计算节点和控制节点上安装zabbix-agent的方式：
rpm -ivh https://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
通过这种方式安装了zabbix-agent还是无法发现主机，因为zabbix-agent上的10050端口和zabbix-server的10051端口并没有打开：
iptables -I INPUT -p tcp --dport -j ACCEPT
iptables -I INPUT -p tcp --dport -j ACCEPT
防火墙放开后，发现zabbix-agent unreachable，查看日志发现：
[root@f-q-c ~]# iptables -I INPUT -p tcp --dport -j ACCEPT
[root@f-q-c ~]# tailf /var/log/zabbix/zabbix_agentd.log
::150758.073 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::150858.107 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::150958.144 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151058.191 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151158.237 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151258.351 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151358.541 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151458.712 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151558.906 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: "172.28.8.15"
::151658.952 failed to accept an incoming connection: connection from "192.168.122.1" rejected, allowed hosts: “172.28.8.15"
192.168.122.1是网关地址，在8.15上是这样一个设备：
: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu qdisc noqueue state UP qlen
link/ether :::d7:: brd ff:ff:ff:ff:ff:ff
inet 192.168.122.1/ brd 192.168.122.255 scope global virbr0
valid_lft forever preferred_lft forever
那么我们调整一下zabbix-agent的配置：
Server=172.28.8.15,192.168.122.1/
然后重启zabbix-agent。
稍等片刻，即可在zabbix页面看到监控的情况（注意增加模板和设置聚合图形）：
