Apache的最大连接数，默认为256个。
修改apache的最大连接数，方法如下：
步骤一
先修改 /path/apache/conf/httpd.conf文件。
代码如下 # vi httpd.conf将“#Include conf/extra/httpd-mpm.conf”前面的 “#” 去掉，保存。
步骤二
代码如下 再修改 /path/apache/conf/extra/httpd-mpm.conf文件。# vi httpd-mpm.conf
找到 这一行
找到文件 /etc/httpd/conf/httpd.conf 并修改下面参数，将默认的256改成1000
代码如下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 该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。
