Heim >Datenbank >MySQL-Tutorial >MySQL的Daemon启动参数_MySQL
假设你的启动脚本是/etc/init.d/mysql 那么找到$bindir/safe_mysqld这行,加上如下参数
-O max_connections=1000 -O wait_timeout=500 -O interactive_timeout=500
当然,得根据你的实际情况加以修改,不过默认值对于我们公司这样负载的服务器是不可想象的……
现在,你的MySQL启动文件有可能看起来像这样:
............
$bindir/safe_mysqld --user=mysql --datadir=$datadir --pid-file=$pid_file -O max_connections=1000 -O wait_timeout=500 -O interactive_timeout=500&
............
修改完成之后,重启MySQL即可,注意一定要先使用mysqladmin shutdown 服务器。
推荐在my.cnf中配置这些参数。
如果你有MySQL的源代码版本,你可以在support-files目录下找到my-huge.cnf, my-large.cnf分别打开看看,选择适合你的那个文件
抄一段话:
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is ) or
# ~/.my.cnf to set user-specific options.
#
# One can in this file use all long options that the program supports.
# If you want to know which options a program support, run the program
# with --help option.
