将wordpress.tar.gz解压直/usr/local/nginx/html/下, 使用浏览器访问121.37.166.201:8081/wp-admin/install.php,输入数据库信息,报错:
问题排查步骤:
1、查看数据库IP地址
[root@master-1 ~]# docker inspect zabbix-mysql | grep "IPAddress" "SecondaryIPAddresses": null, "IPAddress": "", "IPAddress": "172.17.201.1",
进入 /usr/local/nginx/html/wp_config.php配置文件,修改数据库信息:
/** WordPress数据库的名称 */ define('DB_NAME', 'wordpress'); /** MySQL数据库用户名 */ define('DB_USER', 'wordpress'); /** MySQL数据库密码 */ define('DB_PASSWORD', 'wordpress'); /** MySQL主机 */ define('DB_HOST', '172.17.0.1');
重新在浏览器打开wordpress, 问题还是没有解决,依然提示数据库连接失败,,,
2、登录容器数据库,查看密码账号是否正确, ——-没有报错信息,继续排查
[root@master-1 ~]# docker exec -it zabbix-mysql /bin/bash root@0bffe1016a51:/# mysql -uwordpress -pwordpress mysql: [Warning] Using a password on the command line interface can be insecure.

3、在宿主机登录数据库看是否登录成功 ——–宿主机无法连接数据库容器
[root@master-1 ~]# mysql -h 121.37.166.201 -P 3306 -uwordpress -pwordpress ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: The specified module could not be found.(this error comes when I try to lo...
原因:此为8.0新版本的MySQL新特性导致,老版本里机密方式为mysql_native_password,导致认证方式有问题。
解决方法: 登录容器数据库,修改加密方式
1>进入数据库容器: docker exec -it zabbix-mysql /bin/bash
2>登录数据库: mysql -uwordpress -pwordpress
3>修改加密方式:alter user wordpress@'%' identified with mysql_native_password by 'wordpress';
4> 刷新: flush privileges;
5> 退出数据库容器
重新打开wordpress 验证, 可以连到数据库,问题解决。
