最大连接选项不适用于mysqld

mysql file

最大连接选项不适用于mysqld,mysql,file,connection-pooling,Mysql,File,Connection Pooling,我在/etc/my.conf中设置了max_connections=2000，并重新启动了mysqld 但仍max_connectionsapear卡在412 mysql> SHOW VARIABLES LIKE "max_connections"; +-----------------+-------+ | Variable_name | Value | +-----------------+-------+ | max_connections | 412 | +--------

我在

/etc/my.conf

中设置了

max_connections=2000

，并重新启动了

mysqld

但仍

max_connections

apear卡在

mysql>  SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 412  |

我还尝试重新启动mysqld

post
mysql> SET GLOBAL max_connections = 2000;

但在中，我仍然从查询中获得max|u connections | 412
显示变量，如“max_connections”
我通过更改打开文件数量的系统级限制来解决这个问题
检查系统级别。运行命令ulimit-a
将显示输出
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0

virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

打开的文件
限制必须大于最大连接数的值

要更改此选项，请执行以下操作
 sudo nano /etc/security/limits.conf

和添加/编辑
 *   hard    nofile  4096
 *   soft    nofile  4096

现在重新登录服务器，重新启动mysqld并检查
mysql>  SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 2000  |
+-----------------+-------+
