每次我重启MySQL都有这个警告:
[警告]缓冲警告:更改限制:max_connections:214(请求800)
所以我必须改变max_connections变量:
set global max_connections = 800;
但/etc/my.cf已max_connections设定:
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
max_connections = 800
我还修改了mysqld.service:
# Start main service
ExecStart=/usr/bin/mysqld_safe --defaults-file=/etc/my.cnf
我还更新了Centos的最大打开文件,从1024到2000:
ulimit -Sa | grep "open files"
open files (-n) 2000
但问题仍然存在.
