首先先安装清华源的zabbix4.0的RPM
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
ls
rpm -ivh zabbix-release-4.0-2.el7.noarch.rpm
rpm -qa | grep zabbix

vim /etc/yum.repos.d/zabbix.repo
:%s#http://repo.zabbix.com#https://mirrors.tuna.tsinghua.edu.cn/zabbix#g
:%s#gpgcheck=1#gpgcheck=0#g
zabbix-server-mysql zabbix-web-mysql
或者安装zabbix-server-pgsql zabbix-web-pgsql
mysql
pgsql
yum install zabbix-server-mysql zabbix-web-mysql -y
mysql_secure_installation
mysql> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.01 sec)
grant all privileges on zabbix.* to zabbix@localhost identified by '123456';
导入zabbix表结构和初始数据
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p123456 zabbix
4.配置启动zabbix-server
vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=123456
:wq!
5.启动zabbix-server
systemctl start zabbix-server
systemctl enable zabbix-server
[root@neo zabbix]# netstat -lntup
可能有的报错为Zabbix正常启动服务，但是netstat没有端口
netstat -lntp看不到zabbix的10050，10051端口
看日志/var/log/zabbix/zabbix_server.log
[root@neo zabbix]# tail -n 50 zabbix_server.log #tail -n 50 test.log 查询日志尾部最后50行的日志;
2876:20220502:134720.684 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
解决：
[root@neo ~]# find / -name mysql.sock
/tmp/mysql.sock
vim /etc/zabbix/zabbix_server.conf
#修改一下DBSocket就行
DBSocket=/tmp/mysql.sock
systemctl restart zabbix-server
[root@neo zabbix]# netstat -lntup

查看端口号10051
修改时区
vim /etc/httpd/conf.d/zabbix.conf
修改成上海时区
systemctl restart httpd.service
vim /etc/php.ini 也可以配置时区；date.timezone = Asia/Shanghai
检查：
netstat -lntup
5:修改Zabbix前端的PHP配置,并启动httpd
vi /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai
systemctl start httpd
systemctl enable httpd
6:前端zabbix-web的安装
浏览器：http://192.168.199.163/zabbix
遇到在配置界面报错Error connecting to database: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)，是数据库需要授权，如下授权命令：
GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;
后期修改zabbix数据库密码的时候，需要修改的配置文件：
/etc/zabbix/web/zabbix.conf.php
http://192.168.199.163/zabbix/zabbix.php
登录的默认账号密码;
Admin
zabbix
登录成功
