access_logoff; Default: access_loglogs/access.logcombined; Context:http,server,location,ifinlocation,limit_except buffer=size:访问日志缓冲器大小 gzip[=level:压缩级别 flush=time:缓冲器的日志刷新到磁盘时间 if=condition:其他条件 access_logoff:不记录访问日志 nginx_location: 语法: location[=|~|~*|^-]url{ ... } ~和~*的区别:~区分大小写,~*不区分大小写 =:为精确配置 /:为默认配置 其他配置依上至下 nginxrewrite: 语法: rewrite^/(.*)url/$1permanent; 意思是只要匹配如下^/(.*),就跳转至url上,且$1是取前面regex部分括号的内容,结尾的primanent是永久301重定向标记。 regex语法: :去掉特殊字符 ^:起始位置 $:结束位置 *:匹配0次或多次 +:匹配前面的字符一次或多次 ?:匹配前面的字符0次或1次 .:匹配n之外的任何字符 (pattern):匹配括号内字符,并可以在后面匹配,常用$0-$9属性获取值 rewriteflag标记 last:本条规则匹配完成后,继续向下匹配 break:本条规则匹配完成后,不再匹配后面的规则 redirect:返回302临时重定向, permanent:返回301永久重定向 nginx访问认证: 设置密码: [root@e46ae471064econf]#htpasswd-cb/usr/local/nginx/conf/htpasswdliwangliwang 修改conf: [root@e46ae471064econf]#sed-n"48,54p"nginx.conf location/{ roothtml;
