Mysql:my.cnf中的修改没有生效

Question

我my.cnf用以下行更新了我的数据库文件:max_connections=200.之后我停止并启动了mysql服务,以便更改生效.

但由于某种原因,此更改不会影响数据库,因为如果我运行:

mysql> select @@max_connections

它显示最大连接数为100.

显然,还有一些地方可以管理这个价值.我在哪里可以找到它或者我做错了什么？

谢谢您的回复.

Answer 1

确保[mysqld]部分下的max_connections:

例如:

[mysqld]
socket=/path/to/mysql.sock
datadir=/var/lib/mysql
max_connections=200

[client]
#mysql-client settings here..

Answer 2

尝试运行mysqld --verbose --help以查看mysqld实际读取的配置文件以及使用的参数和值.输出将如下所示:

mysqld  Ver 5.0.51a-24-log for debian-linux-gnu on x86_64 ((Debian))

Default options are read from the following files in the given order:
/etc/mysql/my.cnf ~/.my.cnf /usr/etc/my.cnf
The following groups are read: mysql_cluster mysqld server mysqld-5.0

Variables (--variable-name=value)
and boolean options {FALSE|TRUE}  Value (after reading options)

To see what values a running MySQL server is using, type
'mysqladmin variables' instead of 'mysqld --verbose --help'.
