docker安装zabbix出现的问题

1、根据官方文档启动zabbix-web-nginx-mysql容器时，网页访问http://IP+8081，访问失败。

 官方启动zabbix-web-nginx-mysql容器：

# docker run --name zabbix-web-nginx-mysql -t \
      -e DB_SERVER_HOST="mysql-server" \
      -e MYSQL_DATABASE="zabbix" \
      -e MYSQL_USER="zabbix" \
      -e MYSQL_PASSWORD="zabbix_pwd" \
      -e MYSQL_ROOT_PASSWORD="root_pwd" \
      --link mysql-server:mysql \
      --link zabbix-server-mysql:zabbix-server \
      -p 80:80 \
      -d zabbix/zabbix-web-nginx-mysql:latest

浏览器访问http://IP+80时，访问页面失败。 可能是端口映射的问题。 在容器中nginx的端口是8080 。 在启动容器时， 可将端口映射改为  -p  80:8080

# docker run --name zabbix-web-nginx-mysql -t \
      ......

      -p 80:8080 \
      -d zabbix/zabbix-web-nginx-mysql:latest

2、首次网页登陆zabbix提示账号密码错误

1.   默认账号密码，Admin/zabbix。 此处注意 Admin非admin
2.   修改密码    

   1、进入mysql容器
   [root@hecs-136019 ~]# docker exec -it zabbix-mysql /bin/bash
   
   
   
   2、连接数据库 进入zabbix库
   root@5e035217b7f5:/# mysql -uzabbix -pzabbix
   mysql: [Warning] Using a password on the command line interface can be insecure.

   # 查看密码是md5加密状态
   
   
   mysql> select userid,passwd from users;
   +--------+--------------------------------------------------------------+
   | userid | passwd                                                       |

   2 rows in set (0.00 sec)
   

   3、另外开启终端，生成一个md5加密密码 对应的密码为redhat
   
   [root@hecs-136019 ~]# echo -n redhat | openssl md5
   (stdin)= e2798af12a7a0f4f70b4d69efbc25f4d
   

   4、继续在mysql容器里更改Admin密码为redhat
   
   mysql> update users set passwd='e2798af12a7a0f4f70b4d69efbc25f4d' where userid=1;
   Query OK, 1 row affected (0.00 sec)
   Rows matched: 1  Changed: 1  Warnings: 0

3、时区不对

 修改时区为UTC

1、进入zabbix-web-nginx-mysql容器， 找到php-fpm的配置文件

[root@hecs-136019 ~]# docker exec -it zabbix-web-nginx-mysql /bin/bash

 bash-5.1$ cd  /etc/php8/php-fpm.d
 bash-5.1$ ls
 zabbix.conf

2、修改为UTC

 bash-5.1$ vi zabbix.conf 

   php_value[date.timezone] = UTC

4、zabbix-server状态异常

更改/etc/zabbix/zabbix-agentd.conf配置文件
  UnsafeUserParameters=1

[root@hecs-136019 ~]# docker exec  -it zabbix-agent-2 /bin/bash

 5cd564f525d5:/var/lib/zabbix$ ls /etc/zabbix/
 zabbix_agent2.conf  zabbix_agent2.d  zabbix_agentd.d
 5cd564f525d5:/var/lib/zabbix$
 5cd564f525d5:/var/lib/zabbix$ vi /etc/zabbix/zabbix_agent2.conf
   ......
    UnsafeUserParameters=1
   ......

退出容器 重启zabbix-agent容器， 查看zabbix-server状态
