docker安装部署zabbix服务(踩坑记录）

介绍

    zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案,zabbix能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在Linux，Solaris，HP-UX，AIX，Free BSD，Open BSD，OS X等平台上。zabbix由2部分构成，zabbix server与可选组件zabbix agent。
zabbix由2部分构成，zabbix server与可选组件zabbix agent，要想搭建一个Zabbix的工作环境,主要有三个方面（界面、服务器和数据库）可以安装在同一台服务器上，也可以不在同一个服务器。本次使用Docker 开源的应用容器来快速搭建zabbix。dock的安装参考

安装

成功版本：mysql5.7+zabbix4.4.3+nginx1.16
不成功版本：mysql8.0+zabbix4.4.3+nginx1.16

01 docker镜像下载

    搭建ZABBIX所需的软件列表为：RHEL8.0+Nginx+MySQL+ZABBIX。所以需要分别下载相应的镜像.
1、先下载mysql镜像，docker查看mysql镜像，下载STARS比较多的镜像

4、下载zabbix-java-gateway镜像， Zabbix本身不支持直接监控Java，而是使用zabbix-java-gateway监控jvm/tomcat性能

可以看到四个镜像都已经下载完成，下面运行镜像。

02 运行镜像

1、 运行mysql 镜像，创建mysql容器

[root@localhost ~]# docker run -dit -p 3306:3306 --name zabbix-mysql --restart always -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix_pwd" -e MYSQL_ROOT_PASSWORD="root_pwd" mysql

c245a233b8979b833f7bc10f0e6aec62921981ebeea1a787ff3b973aa623bccb

2、运行zabbix-java-gateway镜像，创建zabbix-java-gateway容器

[root@localhost ~]# docker run -dit -p 10052:10052 --restart=always --name=zabbix-java-gateway zabbix/zabbix-java-gateway
9006bd35d41a98c0c03f068c1b5c9edb0f5ff2f28235e97d95f5043e088fffb8

3、运行zabbix-server-mysql镜像，创建zabbix-server-mysql容器。

[root@localhost ~]# docker run -dit -p 10051:10051 --name=zabbix-server-mysql --restart=always -e DB_SERVER_HOST="zabbix-mysql" -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix_pwd" -e MYSQL_ROOT_PASSWORD="root_pwd" -e ZBX_JAVAGATEWAY="zabbix-java-gateway" zabbix/zabbix-server-mysql

db986b0a3cdca4bc028ef9de4eb0a2d528f37d87a648cc6f1fc0327559f52fc3

4、运行zabbix-web-nginx-mysql镜像，创建zabbix-web-nginx-mysql容器

[root@localhost ~]# docker run -dit -p 80:80 --name zabbix-web-nginx-mysql --restart=always -e DB_SERVER_HOST="zabbix-mysql" -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix_pwd" -e MYSQL_ROOT_PASSWORD="root_pwd" -e ZBX_SERVER_HOST="zabbix-server-mysql" zabbix/zabbix-web-nginx-mysql

[root@localhost ~]# 

zabbix所需容器已经全部启动完成。

03 登陆zabbix

1、浏览器访问zabbix地址http://192.168.14.121/zabbix发现打不开，检查docker运行都是正常的，检查容器日志发现是zabbix没有连上mysql数据库，MySQL server is not available。

[root@localhost ~]# docker ps

2、检查容器间网络连接也是正常的，IP都能Ping通，并且本机通过工具访问这个mysql数据库是正常访问的。

3、没有找到问题所在，在论坛找到一个贴子是关于zabbix连接mysql8有bug，说要是zabbix4之后才支持mysql8，但是我的zabbix是4.4.3，应该没有 个问题才对，找不到原因，就只能换成mysq5.7试了一下。

看日志还是报错，是因为前面启动容器的时候指定的DB_SERVER_HOST是容器名称，不是容器的IP，所认还需修改容器的hosts文件，（使用mysql8的时候通过IP和修改hosts文件都试过访问不行）。
4、通过[root@localhost ~]# docker inspect 9a7616f431d8获取到各个容器的IP地址，然后修改容器本机的hosts文件，因为之前我们运行容器的时候指定了将容器的hosts文件挂载本机的/etc/hosts，

[root@localhost docker]# vi /etc/hosts
[root@localhost docker]# more /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.17.0.3 mysql
172.17.0.4 zabbix-java-gateway
172.17.0.5 zabbix-server-mysql
172.17.0.6 zabbix-web-nginx-mysql

5、修改完容器缩主机的hosts文件之后，需要重启容器,再检查容器的日志发现已经正常启动。

[root@localhost docker]# docker stop a57b5a32873b
a57b5a32873b
[root@localhost docker]# docker start a57b5a32873b
a57b5a32873b
[root@localhost docker]# docker stop 3dc55a164c4a
3dc55a164c4a
[root@localhost docker]# docker start 3dc55a164c4a
3dc55a164c4a

5、浏览器访问zabbix页面，输入http://IP/zabbix，打开zabbix首页，其中用户名密码分别是admin/zabbix

总结

    这次安装zabbix遇到很多坑，没有在上面一一说明，这里简单介绍一下，为大家下次能够避够这些问题。
1、首先数据库一开始pull的是最新的mysql8.0导致zabbix连不上数据库，问题原因暂时不清楚，有明白可以告诉我下。
2、换成mysql5.7之后第一次启动容器DB_SERVER_HOST使用的是mysql容器的容器名称，导致zabbix访问不到mysql容器，本想着修改zabbix-server容器的hosts文件，但是发现没有权限修改。无法，删除容器之后重新创建新的容器，指定DB_SERVER_HOST使用的是mysql容器的IP地址，启动服务成功。
3、使用IP虽然可以，但是对于后期维护很麻烦，容器IP会经常变动，而且不便于标识，很多时候创建容器的时候不知道容器的IP，所以找了下资料，查找了几个容器修改hosts文件的方法，感觉都不是特别好用，最后选择了文件挂载的方式，创建时候加运行参数-v /etc/hosts:/etc/host。这样可以随时通过修改本宿主机的hosts文件来改变容器的hosts文件。
