编译安装缓存nginx:
yum install -y gcc gcc-c++ openssl-devel zlib-devel tar xf pcre-8.34.tar.gz cd pcre-8.34 ./configure && make && make install cd .. wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz tar xf ngx_cache_purge-2.3.tar.gz -C /opt/app tar xf nginx-1.4.7.tar.gz cd nginx-1.4.7 ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --add-module=/opt/app/ngx_cache_purge-2.1/
这里我添加一块磁盘做缓存
fdisk /dev/sdb n p 1 w q mkfs.ext3 /dev/sdb1 mkdir /cache mount /dev/sdb1 /cache
nginx-cache主要配置:
