启动mysql,并设置开机自启

[root@localhost opt]# systemctl start mysqld
[root@localhost opt]# systemctl enable mysqld
[root@localhost opt]# systemctl status mysqld
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

查看mysql初始密码

[root@localhost opt]# grep password /var/log/mysqld.log 
2022-12-03T15:19:43.671682Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: aiABK61z!Hg8

使用ALTER语句修改默认密码

[root@localhost opt]# mysql -uroot -p
Enter password:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';

创建zabbix初始数据库

mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> set global log_bin_trust_function_creators = 1;
mysql> flush privileges;
mysql> quit;

导入初始架构和数据，系统将提示您输入新创建的密码。

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -pzabbix -Dzabbix

在导入数据库模式后禁用log_bin_trust_function_创建者选项。

# mysql -uroot -p
password
mysql> set global log_bin_trust_function_creators = 0;
mysql> quit;

为Zabbix server配置数据库
编辑配置文件 /etc/zabbix/zabbix_server.conf

DBPassword=password

为Zabbix前端配置PHP
编辑配置文件 /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf 取消注释并设置’listen’和’server_name’指令。

 listen 80;
 server_name ip地址;

编辑配置文件 /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf 添加nginx监听。acl_users指令。

listen.acl_users = apache,nginx

取消注释并设置正确的时区。

php_value[date.timezone] =  Asia/Shanghai

启动Zabbix server和agent进程
启动Zabbix server和agent进程，并为它们设置开机自启：

systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm

报错

yum -y install  libmysqlclient.so.18

报错

解决方法

mysql> use mysql;
mysql> select user,host,plugin,authentication_string from user; # 查看身份验证插件是否为mysql_native_password
mysql> alter user 'zabbix'@'localhost' identified with mysql_native_password by 'password';  
mysql> select user,host,plugin,authentication_string from user; # 再次查看验证方式，已经改了

原因：

身份验证插件找不到。
原来的身份验证插件为（mysql_native_password）。zabbix找不到新的身份验证插件（caching_sha2_password），
我们将mysql用户使用的登录密码加密规则还原成 mysql_native_password，即可登陆成功。

再次重启zabbix-server即可

再次访问web页面，发现访问失败，但是curl 可以成功访问
在这里插入图片描述
解决方法：修改 /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf
注释掉fastcgi_pass 行，添加fastcgi_pass 127.0.0.1：9000;

再次访问 http://ip

报错

解决方法：
修改配置文件参数 /etc/opt/rh/rh-php72/php.ini
