卸载mariadb
[root@localhost ~]# rpm -qa | grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
[root@localhost ~]# yum remove mariadb-libs -y
配置yum
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://mirrors.163.com|g' /etc/yum.repos.d/Cent*
sed -i 's|$releasever|8-stream|g' /etc/yum.repos.d/Cent*
安装mysql
[root@localhost ~]# yum -y install wget
[root@localhost ~]# yum -y install dnf
[root@localhost ~]# dnf install @mysql 回车输入y，自动下载安装
启动mysql
mysqld --initialize-insecure --user=mysql
systemctl start mysqld
修改mysql密码：
先查看系统自动生成的密码【有的版本不需要这一步】
[root@localhost mysql]# more /var/log/mysqld.log | grep password
2022-05-04T13:06:01.810960Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: jMcXextbs9<j
修改mysql密码
mysql_secure_installation
[root@localhost mysql]# mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root: 【默认直接回车，没有密码；或者是通过mysqld.log查看密码】
The 'validate_password' component is installed on the server.
The subsequent steps will run with the existing configuration
of the component.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : y
New password:
Re-enter new password:
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!

安装zabbix server
a. Install Zabbix repository
yum -y install dnf
rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm
dnf clean all
b. 安装Zabbix server，Web前端，agent
dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent
c. 创建初始数据库
在数据库主机上运行以下代码。
[root@localhost ~]# mysql -u root -p
Enter password:

Query OK, 0 rows affected (0.00 sec)
mysql> quit;
Bye
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-sql-scripts/mysql/server.sql.gz | mysql -uzabbix -p zabbix
d. 为Zabbix server配置数据库
编辑配置文件 /etc/zabbix/zabbix_server.conf
DBPassword=password #增加这一行，密码是刚才创建的密码
e. 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：
启动：
systemctl restart zabbix-server zabbix-agent httpd php-fpm
设置开机启动：
systemctl enable zabbix-server zabbix-agent httpd php-fpm
f. 配置Zabbix前端
安装中文字体：
dnf install -y langpacks-zh_CN连接到新安装的Zabbix前端： http://server_ip_or_name/zabbix
根据Zabbix文件里步骤操作： Installing frontend
配置zabbix web
用户名：Admin
密码：zabbix
zabbix修改Admin密码
模板导出
模板修改前备份
模板修改【linux by zabbix agent】
只保留CPU、内存使用率，网络接口流量
先删除自动发现规则
删除图形里边
删除监控项
删除其他不相关的只剩，如下几项
关联-添加ICMP监控【也可以添加主机的时候单独关联】
通过备份模板恢复模板
添加监控主机
