正在生产线上跑着web前端是nginx+tomcat,现在有这样一个需求,需要对网站的单品页面和列表页设置缓存,不同的页面设置不同的缓存,但是由于开始没有安装ngx_cache_purge这个模块,现在没法直接往配置文件里边写,这时候,就需要在线安装ngx_cache_purge此模块,下边就说下怎么在线编译安装新模块。 安装步骤: 1.首先看下内核和系统的版本号。 [root@vmware1 ~]# uname -a Linux vmware1 2.6.18-308.el5 #1 SMP Tue Feb 21 20:06:06 EST 2012 x86_64 x86_64 x86_64 GNU/Linux [root@vmware1 ~]# lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 5.8 (Final) Release: 5.8 Codename: Final
2.看下编译安装nginx的时候,都编译安装的哪些模块。 [root@vmware1 ~]# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.3.1 built by gcc 4.1.2 20080704 (Red Hat 4.1.2-54) TLS SNI support disabled configure arguments: --user=nginx --group=nginx --prefix=/usr/local/nginx-1.3.1 --with-http_stub_status_module --with-http_ssl_module --with-pcre=/taokey/tools/pcre-8.33
3.下载proxy_cache所需的压缩包ngx_cache_purge-2.1.tar.gz。 [root@vmware1 tools]# wget http://labs.frickle.com/files/ngx_cache_purge-2.1.tar.gz --2013-09-29 11:02:19进到-- http://labs.frickle.com/files/ngx_cache_purge-2.1.tar.gz Resolving labs.frickle.com... 5.9.135.91 Connecting to labs.frickle.com|5.9.135.91|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 10535 (10K) [application/octet-stream] Saving to: `ngx_cache_purge-2.1.tar.gz' 100%[==========================================================================================>] 10,535 --.-K/s in 0s 2013-09-29 11:02:21 (64.8 MB/s) - `ngx_cache_purge-2.1.tar.gz' saved [10535/10535]
4.解压下载好的ngx_cache_purge-2.1.tar.gz这个压缩包 [root@vmware1 tools]# tar -xf ngx_cache_purge-2.1.tar.gz
5.进到之前安装nginx这个软件包的目录 1 [root@vmware1 nginx-1.3.1]# cd /taokey/tools/nginx-1.3.1
6.重新./configure,make编译,不用make install。千万要注意:到这里就可以了,千万不要make install,不然文件就会被覆盖了。 [root@vmware1 nginx-1.3.1]# ./configure --user=nginx --group=nginx --add-module=../ngx_cache_purge-2.1 --prefix=/usr/local/nginx-1.3.1 --with-http_stub_status_module --with-http_ssl_module --with-pcre=/taokey/tools/pcre-8.33 [root@vmware1 nginx-1.3.1]# make
7.需要替换nginx二进制文件,先备份一下原来的启动脚本。 [root@vmware1 nginx-1.3.1]# cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
8.需要把nginx进程杀掉,不然复制会报错 [root@vmware1 nginx-1.3.1]# killall nginx [root@vmware1 nginx-1.3.1]# killall nginx nginx: no process killed [root@vmware1 nginx-1.3.1]# cp ./objs/nginx /usr/local/nginx/sbin/ cp: overwrite `/usr/local/nginx/sbin/nginx'? yes
9.此时,查看下nginx的所有的模块,是否把cache_purge这个模块成功编译进去。 [root@vmware1 nginx-1.3.1]# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.3.1 built by gcc 4.1.2 20080704 (Red Hat 4.1.2-54) TLS SNI support disabled configure arguments: --user=nginx --group=nginx --add-module=../ngx_cache_purge-2.1 --prefix=/usr/local/nginx-1.3.1 --with-http_stub_status_module --with-http_ssl_module --with-pcre=/taokey/tools/pcre-8.33
10.开启nginx. [root@vmware1 nginx-1.3.1]# /usr/local/nginx/sbin/nginx [root@vmware1 nginx-1.3.1]# netstat -anpt | grep nginx tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6205/nginx
到此为止,实验结束。
