zabbix安装
在上一篇文章当中，已经配置好了yum源，那么接下来的安装过程就会显得非常简单了。
安装zabbix各种服务
yum install zabbix-server-mysql
yum install zabbix-anget
yum install zabbix-web-mysql
创建mysql数据库，并且导入初始化数据库
create database zabbix character set utf8 collate utf8_bin;(这个命令是放到mysql客户端里面执行的)
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
这里需要注意的是，创建数据库的时候一定要加上后面的字符集和collate选项，不然zabbix-server和前端页面连接数据库时会报错。
修改zabbix配置，用于连接数据库
打开文件/etc/zabbix/zabbix_server.conf,修改数据库配置
DBHost=127.0.0.1
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
关闭selinux
setenforce 0
需要先关闭selinux,如果不关闭，后面可能server起不来，会报如下的错
[root@localhost msb_5_7_21]# service zabbix-server start
Redirecting to /bin/systemctl start zabbix-server.service
Job for zabbix-server.service failed because a configured resource limit was exceeded. See "systemctl status zabbix-server.service" and "journalctl -xe" for details.

开启zabbix-server,观察后台日志
service zabbix-server start
service zabbix-agent start
tail -10f /var/log/zabbix
开启httpd服务并且关闭防火墙
service httpd start;
systemctl stop firewalld.service
修改/etc/php-fpm.d/zabbix.conf的时间设置
php_value date.timezone Asia/Shanghai
跟着https://www.zabbix.com/documentation/4.4/manual/installation/install#installing_frontend上面的步骤来修改前端页面的配置
设置开机启动zabbix-server,zabbis-agent和httpd
systemctl enable zabbix-server zabbix-agent httpd
