安装zabbix遇到的问题
Error downloading packages:
  zabbix-server-mysql-3.2.11-1.el7.x86_64: [Errno 256] No more mirrors to try.

解决yum check-update检查可更新的程序就可继续安装
启动zabbix遇到的一些错误
# systemctl restart zabbix-server zabbix-agent httpd
# systemctl enable zabbix-server zabbix-agent httpd
[root@localhost ~]# netstat -lntp //死活看不到服务端

查看日志
cat /var/log/zabbix/zabbix_server.log 
报错
6603:20190824:031515.677 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) //显示找不到mysql.sock的文件

find / -name mysql.sock搜索下载那里
# find / -name mysql.sock
/tmp/mysql.sock  找到是在tmp下

这时候编辑zabbix-server的配置文件
找到#DBSocket改为DBSocket=/tmp/mysql.sock即可
更改完建议重启
