nginx实现负载均衡及静态资源处理
nginx 安装
首先安装pcre
./configure
make
make install
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make
make install
nginx 负载均衡配置
upstream dyRes {
server 127.0.0.1:8081;
server 127.0.0.1:8082;
}
upstream staticRes {
server 127.0.0.1:81;
server 127.0.0.1:82;
}
server {
listen 80;
server_name l27.0.0.1;
charset gbk;
#access_log logs/host.access.log main;
location ~* \.(ico|gif|bmp|jpg|jpeg|png|swf|js|css|html|htm)$ {
access_log on;
index index.html index.htm;
proxy_pass http://staticRes ;
}
location ~* \.(js)$ {
access_log on;
index index.html index.htm;
proxy_pass http://staticRes ;
}
#dwr 特殊处理
location ^~/cprime/dwr {
access_log on ;
index index.jsp ;
proxy_pass http://dyRes ;
}
location ~* \.(action|jsp)$ {
access_log on ;
index /cprime/example/login.jsp ;
proxy_pass http://dyRes ;
}
#设定查看Nginx状态的地址
location /NginxStatus {
stub_status on;
access_log on;
auth_basic "NginxStatus";
# auth_basic_user_file conf/htpasswd;
}
}
静态资源缓存配置
在serser同级添加
proxy_cache_path /usr/local/resource/cache levels=1:2 keys_zone=NAME:10m inactive=1d max_size=300m ;
修改location如下
location ~* ^.+.(ico|gif|bmp|jpg|jpeg|png|swf)$ {
root /usr/local/resource/;
access_log on;
index index.html index.htm;
expires 5d;
proxy_cache NAME;#使用NAME这个keys_zone
proxy_cache_valid 200 302 1h;#200和302状态码保存1小时
proxy_cache_valid 301 1d;#301状态码保存一天
proxy_cache_valid any 1m;#其它的保存一分钟
}
proxy_cache 用来缓存静态资源
