Apache常用配置项

301是永久重定向

302是临时重定向

编辑虚拟主机的配置文件需要用到apache的rewrite模块

所以要用要先检查apache是否安装了rewrite模块

# ./bin/apachectl -M | grep rewrite

 rewrite_module (shared)

# vim /usr/local/apache/conf/extra/httpd-vhosts.conf

<IfModule mod_rewrite.c>

     RewriteEngine on

     RewriteCond %{HTTP_HOST} ^www.aaa.com$ [OR]

     RewriteCond %{HTTP_HOST} ^www.bbb.com$

     RewriteRule ^/(.*)$ http://www.fansik.com/$1 [R=301,L]

</IfModule>

Apache日志切割

CustomLog "|/usr/local/apache/bin/rotatelogs -l /usr/local/apache/logs/discuz-access_%Y%m%d_log 86400" combined

Apache不记录以下结尾的内容

    SetEnvIf Request_URI ".*.gif$" image-request

    SetEnvIf Request_URI ".*.jpg$" image-request

    SetEnvIf Request_URI ".*.png$" image-request

    SetEnvIf Request_URI ".*.bmp$" image-request

    SetEnvIf Request_URI ".*.swf$" image-request

    SetEnvIf Request_URI ".*.js$" image-request

    SetEnvIf Request_URI ".*.css$" image-request

CustomLog "|/usr/local/apache/bin/rotatelogs -l /usr/local/apache/logs/discuz-access_%Y%m%d_log 86400" combined env=!image-request

Apache配置静态缓存

<IfModule mod_expires.c>
  ExpiresActive on
  ExpiresByType image/gif "access plus 1 days"
  ExpiresByType image/jpeg "access plus 24 hours"
  ExpiresByType image/png "access plus 24 hours"
  ExpiresByType text/css "now plus 2 hours"
  ExpiresByType application/x-javascript "now plus 2 hours"
  ExpiresByType application/x-shockwave-flash "now plus 2 hours"
  ExpiresDefault "now plus 0 min"
</IfModule>

加载好上面的配置后可用curl来检查一下哦

# curl -x127.0.0.1:80 'http://120.55.194.217/static/image/common/logo.png' -I

如果出现红字，说明配置成功了，缓存时间是86400秒

如果没效果记得查看一下模块的开关是不是打开了
