zabbix组件分离安装

zabbix-server：172.25.250.5

zabbix-web ：172.25.250.10

zabbix-db ：172.25.250.6

1、关闭防火墙

2、设置selinux为disabled(实验中设置为宽松，会导致数据库连接不上)

3、设置镜像源（epel“用于安装nginx”，zabbix）（清华镜像站或者网易，阿里）

[epel]
name = epel
baseurl = https://mirrors.tuna.tsinghua.edu.cn/epel/8/Everything/x86_64/
enabled = 1
gpgcheck = 0
[zabbix]
name = zabbix
baseurl = https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/5.0/rhel/8/x86_64/
enabled = 1
gpgcheck = 0

1、安装软件包
	yum -y install zabbix-sever-mysql mariadb mariadb-server
2、启动数据库
	systemctl restart mariadb
3、初始化数据库
	mysql_secure_installation
5、设置数据库免密登录
	vim /etc/my.cnf
		[client-server]
		user = root
		password = 123

6、创建数据库
	mysql -e "create database zabbix character set utf8 collate utf8_bin;"
7、授权用户
	create user zabbix@localhost identified by "123";
	mysql -e "grant all privileges on zabbix.* to zabbix@'%' identified by '123';"
8、刷新数据库
	flush privileges;
9、导入zabbix数据表
	zcat /usr/share/doc/zabbix-server-mysql/create.sql.gz |mysql -uzabbix -p -h 172.25.250.6 zabbix
10、重启数据库
	systemctl restart mariadb

1、安装软件包
	yum -y install zabbix-sever-mysql
2、修改配置文件
	sed -i 's/^# DBHost.*/DBHost=172.25.250.6/' /etc/zabbix/zabbix_server.conf 
	sed -i 's/^# DBPassword.*/DBPassword=123/' /etc/zabbix/zabbix_server.conf 
3、重启zabbix-server服务
	systemctl restert zabbix-server

1、安装软件包
	yum -y install zabbix-web-mysql zabbix-nginx-conf
2、修改nginx监听得端口
	sed -i 's/^#        listen.*/        listen         80;' /etc/nginx/conf.d/zabbix.conf
	sed -i 's/^#        server_name.*/        server_name    172.25.250.10;/' /etc/nginx/conf.d/zabbix.conf
3、修改时区为Asia/shanghai
	sed -i 's/; php_value[date.timezone].*/php_value[date.timezone]=Asia/shanghai/' /etc/php-fpm.d/zabbix.conf 
4、修改php.ini的时区
5、重启nginx和php-fpm服务
