使用apache的朋友可能會經常碰到要調整apache環境的連接數與并發數下面我來給大家介紹怎么修改連接數/apache并發數.
Apache的最大連接數，默認為256個。修改apache的最大連接數，方法如下：
步驟一:先修改 /path/apache/conf/httpd.conf文件。
- # vi httpd.conf
- 將“#Include conf/extra/httpd-mpm.conf”前面的 “#” 去掉，保存。
步驟二:再修改 /path/apache/conf/extra/httpd-mpm.conf文件。
- # vi httpd-mpm.conf
找到 這一行,找到文件 /etc/httpd/conf/httpd.conf 并修改下面參數，將默認的256改成1000
- KeepAliveTimeout 15
- ##
- ## Server-Pool Size Regulation (MPM specific)
- ##
- # prefork MPM
- # StartServers: number of server processes to start
- # MinSpareServers: minimum number of server processes which are kept spare
- # MaxSpareServers: maximum number of server processes which are kept spare
- # ServerLimit: maximum value for MaxClients for the lifetime of the server
- # MaxClients: maximum number of server processes allowed to start
- # MaxRequestsPerChild: maximum number of requests a server process serves
- StartServers 8
- MinSpareServers 5
- MaxSpareServers 20
- ServerLimit 1000
- MaxClients 1000
- MaxRequestsPerChild 4000
- ServerLimit 該指令一定要放在第一行。
修改后，一定不要apachectl restart，而是先 apachectl stop 然后再 apachectl start才可以。
