摘要:nginx: [emerg] unknown directive "if("
今天在配置nginx 301跳转时遇到一点小问题`nginx: [emerg] unknown directive "if(" /usr/local/nginx/config/xxxxx.conf:9`看看我的原来的配置```if($Host != 'xxxx.cn'){ rewrite ^/(.*)$ http://xxxx.cn/$1 permanent;}```这会出现问题有2个1. 留空原则:在nginx配置中很多的关键词前后都需要增加空格以保证配置的读取2. $Host应全部为小写。所以正确的写法是这样的```if ( $Host != 'xxxx.cn'){ rewrite ^/(.*)$ http://xxxx.cn/$1 permanent;}```------# 附加nginx rewrite 伪静态配置参数详细说明(转)nginx rewrite 伪静态配置参数和使用例子 附正则使用说明正则表达式匹配,其中:* ~ 为区分大小写匹配 * ~* 为不区分大小写匹配 * !~和!~*分别为区分大小写不匹配及不区分大小写不匹配文件及目录匹配,其中:* -f和!-f用来判断是否存在文件 * -d和!-d用来判断是否存在目录 * -e和!-e用来判断是否存在文件或目录 * -x和!-x用来判断文件是否可执行flag标记有:* last 相当于Apache里的[L]标记,表示完成rewrite * break 终止匹配, 不再匹配后面的规则 * redirect 返回302临时重定向 地址栏会显示跳转后的地址 * permanent 返回301永久重定向 地址栏会显示跳转后的地址一些可用的全局变量有,可以用做条件判断(待补全)```$args$content_length$content_type$document_root$document_uri$host$http_user_agent$http_cookie$limit_rate$request_body_file$request_method$remote_addr$remote_port$remote_user$request_filename$request_uri$query_string$scheme$server_protocol$server_addr$server_name$server_port$uri```结合QeePHP的例子```if (!-d $request_filename) { rewrite ^/([a-z-A-Z]+)/([a-z-A-Z]+)/?(.*)$ /index.php?namespace=user&controller=$1&action=$2&$3 last; rewrite ^/([a-z-A-Z]+)/?$ /index.php?namespace=user&controller=$1 last; break;}```多目录转成参数```abc.domian.com/sort/2 => abc.domian.com/index. php?act=sort&name=abc&id=2if ($host ~* (.*)\.domain\.com) {set $sub_name $1;rewrite ^/sort\/(\d+)\/?$ /index.php?act=sort&cid=$sub_name&id=$1 last;}```目录对换```/123456/xxxx -> /xxxx?id=123456rewrite ^/(\d+)/(.+)/ /$2?id=$1 last;```例如下面设定nginx在用户使用ie的使用重定向到/nginx-ie目录下:```if ($http_user_agent ~ MSIE) {rewrite ^(.*)$ /nginx-ie/$1 break;}```目录自动加“/”```if (-d $request_filename){rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;}```禁止htaccess```location ~/\.ht { deny all;}```禁止多个目录```location ~ ^/(cron|templates)/ { deny all; break;}```禁止以/data开头的文件可以禁止/data/下多级目录下.log.txt等请求;```location ~ ^/data { deny all;}```禁止单个目录不能禁止.log.txt能请求```location /searchword/cron/ { deny all;}```禁止单个文件```location ~ /data/sql/data.sql { deny all;}```给favicon.ico和robots.txt设置过期时间;这里为favicon.ico为99 天,robots.txt为7天并不记录404错误日志```location ~(favicon.ico) { log_not_found off; expires 99d; break;}location ~(robots.txt) { log_not_found off; expires 7d; break;}```设定某个文件的过期时间;这里为600秒,并不记录访问日志```location ^~ /html/scripts/loadhead_1.js { access_log off; root /opt/lampp/htdocs/web; expires 600; break;}```文件反盗链并设置过期时间这里的return 412 为自定义的http状态码,默认为403,方便找出正确的盗链的请求```rewrite ^/ http://leech.c1gstudio.com/leech.gif;```显示一张防盗链图片```access_log off;```不记录访问日志,减轻压力```expires 3d```所有文件3天的浏览器缓存```location ~* ^.+\.(jpg|jpeg|gif|png|swf|rar|zip|css|js)$ { valid_referers none blocked *.c1gstudio.com *.c1gstudio.net localhost 208.97.167.194; if ($invalid_referer) { rewrite ^/ http://leech.c1gstudio.com/leech.gif; return 412; break; } access_log off; root /opt/lampp/htdocs/web; expires 3d; break;}```只充许固定ip访问网站,并加上密码```root /opt/htdocs/www;allow 208.97.167.194;allow 222.33.1.2;allow 231.152.49.4;deny all;auth_basic "C1G_ADMIN";auth_basic_user_file htpasswd;```将多级目录下的文件转成一个文件,增强seo效果```/job-123-456-789.html 指向/job/123/456/789.htmlrewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /job/$1/$2/jobshow_$3.html last;```将根目录下某个文件夹指向2级目录如`/shanghaijob/` 指向 `/area/shanghai/`如果你将`last`改成`permanent`,那么浏览器地址栏显是 `/location/shanghai/````rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;```上面例子有个问题是访问`/shanghai` 时将不会匹配```rewrite ^/([0-9a-z]+)job$ /area/$1/ last;rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;```这样`/shanghai` 也可以访问了,但页面中的相对链接无法使用,如`./list_1.html`真实地址是`/area/shanghia/list_1.html`会变成`/list_1.html`,导至无法访问。那我加上自动跳转也是不行咯`-d $request_filename`它有个条件是必需为真实目录,而我的rewrite不是的,所以没有效果```if (-d $request_filename){rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;}```知道原因后就好办了,让我手动跳转吧```rewrite ^/([0-9a-z]+)job$ /$1job/ permanent;rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;```文件和目录不存在的时候重定向:```if (!-e $request_filename) { proxy_pass http://127.0.0.1/;}```域名跳转```server{ listen 80; server_name jump.c1gstudio.com; index index.html index.htm index.php; root /opt/lampp/htdocs/www; rewrite ^/ http://www.c1gstudio.com/; access_log off;}```多域名转向```server_name http://www.c1gstudio.com/ http://www.c1gstudio.net/;index index.html index.htm index.php;root /opt/lampp/htdocs;if ($host ~ "c1gstudio\.net") { rewrite ^(.*) http://www.c1gstudio.com$1/ permanent;}```三级域名跳转```if ($http_host ~* "^(.*)\.i\.c1gstudio\.com$") { rewrite ^(.*) http://top.yingjiesheng.com$1/; break;}```域名镜向```server{ listen 80; server_name mirror.c1gstudio.com; index index.html index.htm index.php; root /opt/lampp/htdocs/www; rewrite ^/(.*) http://www.c1gstudio.com/$1 last; access_log off;}```某个子目录作镜向```location ^~ /zhaopinhui { rewrite ^.+ http://zph.c1gstudio.com/ last; break;}```discuz ucenter home (uchome) rewrite```rewrite ^/(space|network)-(.+)\.html$ /$1.php?rewrite=$2 last;rewrite ^/(space|network)\.html$ /$1.php last;rewrite ^/([0-9]+)$ /space.php?uid=$1 last;```discuz 7 rewrite```rewrite ^(.*)/archiver/((fid|tid)-[\w\-]+\.html)$ $1/archiver/index.php?$2 last;rewrite ^(.*)/forum-([0-9]+)-([0-9]+)\.html$ $1/forumdisplay.php?fid=$2&page=$3 last;rewrite ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ $1/viewthread.php?tid=$2&extra=page\%3D$4&page=$3 last;rewrite ^(.*)/profile-(username|uid)-(.+)\.html$ $1/viewpro.php?$2=$3 last;rewrite ^(.*)/space-(username|uid)-(.+)\.html$ $1/space.php?$2=$3 last;rewrite ^(.*)/tag-(.+)\.html$ $1/tag.php?name=$2 last;```给discuz某版块单独配置域名```server_name bbs.c1gstudio.com news.c1gstudio.com;location = / { if ($http_host ~ news\.c1gstudio.com$) { rewrite ^.+ http://news.c1gstudio.com/forum-831-1.html last;
