如果服务器访问量较大，Nginx日志占用空间也是个很大的问题，也不可能每天都手工清除日志，久而久之硬盘空间。。。
此脚本用于每天定时切割日记，备份30天内的日志数据备查，并删除30前备份的数据。

#/bin/bash
#Create by https://www.haiyun.me
log_path="/home/wwwlogs"
mkdir -p $log_path/$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/$(date -d "yesterday" +"%d")  
for logname in $(ls /home/wwwlogs/*.log |awk -F/ '{print $NF}')
do
         mv $log_path/$logname $log_path/$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/$(date -d "yesterday" +"%d")/$logname
 done
kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`
find $log_path -type d -mtime +30 -exec rm {} \;

将此脚本添加到计划任务：

echo "30 1 * * * sh /path/file.sh" > /etc/cron.d/nginx
#每天凌晨1点30执行任务

mkdir -p ~/.vim/syntax/
wget -O ~/.vim/syntax/nginx.vim https://www.haiyun.me/usr/uploads/2012/05/2410071208.vim
echo "au BufRead,BufNewFile /usr/local/nginx/conf/* set ft=nginx" >> ~/.vimrc

效果图如下：

安装编译环境及相关组件：

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 \
libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl \
curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap \
openldap-devel nss_ldap openldap-clients openldap-servers unzip

编译安装PCRE、Nginx及缓存清除模块ngx_cache_purge：

/usr/local/src/
wget http://sourceforge.net/projects/pcre/files/pcre/8.30/pcre-8.30.zip
unzip pcre-8.30.zip 
cd pcre-8.30
./configure 
make && make install  
cd ..
wget http://labs.frickle.com/files/ngx_cache_purge-1.2.tar.gz
tar zxvf ngx_cache_purge-1.2.tar.gz 
wget http://nginx.org/download/nginx-1.0.15.tar.gz
tar zxvf nginx-1.0.15.tar.gz 
cd nginx-1.0.15
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module  \
--with-http_gzip_static_module --add-module=../ngx_cache_purge-1.2
make && make install

substitutions_filter是Nginx的一个扩展模块，用来搜索并替换应答内容中的文本，配合nginx的反向代理有妙用哦。
添加此模块需重新编译Nginx，LNMP编译升级请参考：LNMP平滑升级。
首先获取substitutions_filter：

yum -y install subversion
svn checkout http://substitutions4nginx.googlecode.com/svn/trunk/ substitutions4nginx-read-only

编译Nginx时添加：

./configure --add-module=/path/substitutions4nginx-read-only

使用语法：

subs_filter 源字符 目标字符 [gior] 
#g:替换全部
#o:替换首个
#i:不区分大小写
#r:使用正则替换

使用范例：

location / {
    subs_filter_types text/html text/css text/xml; #替换的文件类型
    subs_filter st(\d*).onovps $1.www.haiyun.me ir; #
    subs_filter www.haiyun.me www.haiyun.me;
}

注意：开启GZIP后不能替换，需关闭：

proxy_set_header Accept-Encoding "";
