mysql> create database zabbix_proxy character set utf8 collate utf8_bin; 

mysql> GRANT ALL PRIVILEGES ON zabbix_proxy.* TO 'zabbix_proxy'@'%';

mysql> flush privileges;

mysql> exit

导入初始数据
zcat /usr/share/doc/zabbix-proxy-mysql-5.0.38/schema.sql.gz | mysql -uzabbix_proxy -pzabbix zabbix_proxy

mysql  -uzabbix_proxy -p

mysql> user zabbix_proxy;
mysql> show tables;

mysql> exit

systemc restart mysql

 修改proxy.conf配置文件

[root@test-03 ~]# grep '^[a-Z]' /etc/zabbix/zabbix_proxy.conf

报错问题

1、 20949:20231018:080621.069 database is down: reconnecting in 10 seconds
 20949:20231018:080631.069 [Z3001] connection to database 'zabbix_proxy' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sok' (2)

因为zabbix-proxy找不到 /var/lib/mysql/mysql.sok 所以报错

mysq -uroot -proot
mysql> SHOW VARIABLES LIKE 'socket';
+---------------+-----------------+
| Variable_name | Value           |
+---------------+-----------------+
| socket        | /tmp/mysql.sock |
+---------------+-----------------+
1 row in set (0.00 sec)

确认sock安装路径，在zabbix_proxy.conf 203修改配置

vim /etc/zabbix/zabbix_proxy.conf

203  DBSocket=/tmp/mysql.sock

2、25305:20231018:081433.392 using configuration file: /etc/zabbix/zabbix_proxy.conf 25305:20231018:081433.394 [Z3001] connection to database 'zabbix_proxy' failed: [2059] Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory 25305:20231018:081433.394 Cannot connect to the database.

根据错误信息，你遇到了一个关于 MySQL 认证插件 caching_sha2_password 的问题。这个插件要求共享对象文件 caching_sha2_password.so，但在指定的路径 /usr/lib64/mysql/plugin/ 下找不到该文件。

解决此问题的方法是，你可以尝试更改 MySQL 用户的认证插件，以使用较旧的 mysql_native_password 插件，这在较旧版本的 MySQL 中更常见。以下是解决方法：

mysql> ALTER USER 'zabbix_proxy'@'%' IDENTIFIED WITH 'mysql_native_password' BY 'zabbix';
Query OK, 0 rows affected (0.07 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.03 sec)

mysql>
mysql> exit

systemctl restart mysql
