mysql-error --(ERROR 1135 (HY000): Can't create a new thread (errno 11); if you are not out)

报错信息：

ERROR 1135 (HY000): Can't create a new thread (errno 11); if you are not out

解决办法：

# 查看限制情况
[root@SLAVE_115_28_222_53 ~]# cat /proc/`pidof mysqld`/limits | egrep "(processes|files)"
Max processes             1024                 unlimited            processes
Max open files            160000               160000               files
### 解决办法
# 调整当前mysqld限制
[root@localhost ~]# echo -n "Max processes=514857:514857" > /proc/`pidof mysqld`/limits
# 配置文件，增加配置
# vim /etc/security/limits.d/90-nproc.conf
mysql  soft  nproc  514857    # 添加这行
