必须初始化修改密码,不然大部分操做会报错,如:

mysql> use mysql;

通常报错的项是php的参数不符合要求,在/etc/php.ini中找到报错的项,将参数改成图中Required对应的参数便可web
vim /etc/php.ini post_max_size = 16M max_execution_time = 300 max_input_time = 300 date.timezone =Asia/Shanghai #保存退出,重启httpd和zabbix-server,刷新浏览器网页

严重性:Average
建议:
1:内存调度问题
在zabbix_server.conf配置文件中
增长初始化进程 StartPollers=12
重启zabbix-serversql
2:进程占用问题
修改zabbix_server.conf中discovery进程数量
StartDiscoverers=5
重启zabbix-servershell
PHP7.x以上版本的报错,还没有解决数据库
