cmd命令行切换到C:\wamp\bin\apache\apache2.4.9\bin目录 
输入httpd -t命令 错误如下： 
1.Syntax error on line 92 of C:/Apache24/conf/extra/httpd-ssl.conf: 
SSLSessionCache: ‘shmcb’ session cache not supported (known names: ). Maybe you need to load the appropriate socache module (mod_socache_shmcb?

解决方法：在httpd.conf中找到下面这句话# 
LoadModule socache_shmcb_module modules/mod_socache_shmcb.so 
取消注释（删掉前面的”#”）

apache配置文件语法错误命令：httpd -t
