1 建立用戶及組
/usr/sbin/groupadd www /usr/sbin/useradd -g www www
2 安裝pcre 讓Nginx反向代理支持rewrite 方便以后所需
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.8.tar.gz
tar zxvf pcre-7.8.tar.gz
cd pcre-7.8/
./configure
make && make install
3 安裝Nginx反向代理
wget http://sysoev.ru/ nginx /nginx-0.7.58.tar.gz
tar zxvf nginx-0.7.58.tar.gz
cd nginx-0.7.58/
./configure --user=www --group=www --prefix=/usr/
local/webserver/nginx --with-http_stub_status_module
--with-http_ssl_module --with-cc-opt='-O2' --with-cpu-opt
=opteronmake && make install
注意上文中的--with-cc-opt='-O2' --with-cpu-opt=opteron 這是編譯器優(yōu)化,目前最常用的是-02 而不是3.后面對(duì)應(yīng)CPU的型號(hào)。
第2部分:配置及優(yōu)化配置文件
1 Nginx.conf 配置文件:
user www www;
worker_processes 4;
# [ debug | info | notice | warn | error | crit ]
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that
can be opened by this process.worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 51200;
}
http
{
include mime.types;
default_type application/octet-stream;
source_charset GB2312;
server_names_hash_bucket_size 256;
client_header_buffer_size 256k;
large_client_header_buffers 4 256k;
#size limits
client_max_body_size 50m;
client_body_buffer_size 256k;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
#參數(shù)都有所調(diào)整.目的是解決代理過程中出現(xiàn)的一些502 499錯(cuò)誤
sendfile on;
tcp_nopush on;
keepalive_timeout 120; #參數(shù)加大,以解決做代理時(shí)502錯(cuò)誤
tcp_nodelay on;
include vhosts/upstream.conf;
include vhosts/bbs.linuxtone.conf;
}
2 upstream.conf 配置文件(這也是做負(fù)載的配置方法
upstream.conf upstream bbs.linuxtone.com { server 192.168.1.4:8099; }3 站點(diǎn)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/;
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 $proxy_add_x_forwarded_for;
client_max_body_size 50m;
client_body_buffer_size 256k;
proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 60;
proxy_buffer_size 256k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
proxy_temp_file_write_size 256k;
proxy_next_upstream error timeout invalid_header http_500
http_503 http_404;proxy_max_temp_file_size 128m;
proxy_pass http://bbs.linuxtone.com;
}
參數(shù)都有所調(diào)整.目的是解決代理過程中出現(xiàn)的一些502 499錯(cuò)誤
#Add expires header for static content location ~* \.(jpg|jpeg|gif|png|swf)$ { 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; }關(guān)于Nginx中怎么實(shí)現(xiàn)反向代理就分享到這里了，希望以上內(nèi)容可以對(duì)大家有一定的幫助，可以學(xué)到更多知識(shí)。如果覺得文章不錯(cuò)，可以把它分享出去讓更多的人看到。
