Nginx实现反向代理和负载均衡的配置
1、nginx安装好,最好是tengine
2 upstream.conf 配置文件(这也是做负载的配置方法)
upstream.conf
upstream bbs.linuxtone.com {
server 192.168.1.4:8099;
}
upstream bbs.linuxtone.com {
server 192.168.1.4:8099;
}
3 站点配置文件
bbs.linuxtone.conf
server
{
listen 80;
server_name bbs.linuxtone.conf;
charset GB2312;
index index.html index.htm;
root /date/wwwroot/linuxtone/;
bbs.linuxtone.conf
server
{
listen 80;
server_name bbs.linuxtone.conf;
charset GB2312;
index index.html index.htm;
root /date/wwwroot/linuxtone/;
location ~ ^/NginxStatus/ {
stub_status on;
access_log off;
}
location / {
root /date/wwwroot/linuxtone/;
proxy_redirect off ;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 50m;
client_body_buffer_size 256k;
proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 60;
proxy_buffer_size 256k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
proxy_temp_file_write_size 256k;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
proxy_max_temp_file_size 128m;
proxy_pass http://bbs.linuxtone.com;
}
#参数都有所调整.目的是解决代理过程中出现的一些502 499错误
#Add expires header for static content
location ~* \.(jpg|jpeg|gif|png|swf)$ {
if (-f $request_filename) {
root /date/wwwroot/linuxtone/;
expires 1d;
break;
}
}
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /exp/nginxlogs/bbs.linuxtone_access.log access;
}
注:第二种代理方式
nginx 处理下图片,html等静态的东西.其它动态由apache处理.因此apache也需要做一些参数调整.
设置图片等过期时间.缓解请求.
如果源与nginx在同一台机器建议使用如下方法:
location / {
proxy_pass http://192.168.1.4:8099/;
proxy_redirect default ;
}
针对不同的目录进行代理把下面的配置放到根目录代理的上面
location /linuxtone/ {
proxy_pass http://192.168.1.4:8099/linuxtone/;
proxy_redirect default ;
}
