Apache访问日志切割和自定义格式

十周四次课（12月21日） 11.22 访问日志不记录静态文件 11.23 访问日志切割 11.24 静态元素过期时间

扩展 apache日志记录代理IP以及真实客户端IP

apache只记录指定URI的日志

修改apache日志不记录图片，js和css访问日志

vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
在CustomLog 上方添加img标记，在添加env=!img

    ServerAlias www.123.com 1123.com.cn
     .c>
        RewriteEngine on
        RewriteCond %{HTTP_HOST} !^123.com$
        RewriteRule ^/(.*)$ http://www.123.com/$1 [R=301,L]
     
    ErrorLog "logs/123.com-error_log"
    SetEnvIf Request_URI ".*\.gif$" img
    SetEnvIf Request_URI ".*\.jpg$" img 
    SetEnvIf Request_URI ".*\.png$" img

    SetEnvIf Request_URI ".*\.swf$" img
    SetEnvIf Request_URI ".*\.js$" img
    SetEnvIf Request_URI ".*\.css$" img
    CustomLog "logs/123.com-access_log" combined env=!img

查看日志记录情况
tail /usr/local/apache2.4/logs/abc.com-access_log

apache日志切割

vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

    DocumentRoot "/data/wwwroot/123.com"
    ServerName 123.com
    ServerAlias www.123.com 1123.com.cn
     
        RewriteEngine on
        RewriteCond %{HTTP_HOST} !^123.com$
        RewriteRule ^/(.*)$ http://www.123.com/$1 [R=301,L]
     
    ErrorLog "logs/123.com-error_log"
    SetEnvIf Request_URI ".*\.gif$" img
    SetEnvIf Request_URI ".*\.jpg$" img
    SetEnvIf Request_URI ".*\.png$" img
    SetEnvIf Request_URI ".*\.bmp$" img
    SetEnvIf Request_URI ".*\.swf$" img
    SetEnvIf Request_URI ".*\.js$" img
    SetEnvIf Request_URI ".*\.css$" img
    CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/123.com-access_%Y%m%d.log 86400"  combined env=!img

-l是已当前系统时间切割，不加-l就是ust美国时间，在中国是cst
86400秒就是一天

浏览器访问网站的图片时会把静态的文件缓存在本地电脑里，这样下次再访问时就不用去远程下载了
配置静态文件过期时间，需要启动expires_module模块
/usr/local/apache2.4/bin/apachectl -M| grep expires_module
vim /usr/local/apache2.4/conf/httpd.conf
LoadModule expires_module modules/mod_expires.so

/usr/local/apache2.4/bin/apachectl -t
/usr/local/apache2.4/bin/apachectl graceful
