一、官网下载nginx for windows包
下载链接：nginx官网
解压后如图
nginx.png
二、三种配置方式
1、域名访问方式（示例：1个nignx拖3个iserver，三个域名请求）
（1）配置文件路径：./nginx/conf/nginx.conf
（2）默认配置文件
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
#设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
（3）可直接在nginx目录输入
start nginx
启动nginx，浏览器输入http://localhost，即可看到如下界面即启动成功

输入
nginx -s quit
退出nginx
（4）修改配置问题如下
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
upstream webservers1 {
server 192.168.46.228:8090 weight=1;
server 192.168.46.228:8091 weight=1;
server 192.168.46.228:8092 weight=1;
}
server {
listen 8888;
server_name 192.168.46.228;
#charset koi8-r;
#access_log logs/host.access.log main;
#location / {
#root html;
#index index.html index.htm;
proxy_pass http://webservers1;
proxy_set_header Host $http_host;
#}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
server {
listen 8887;
server_name 192.168.46.228;
location / {
proxy_pass http://webservers1;
proxy_set_header Host $http_host;
}
}
server {
listen 8886;
server_name 192.168.46.228;
location / {
proxy_pass http://webservers1;
proxy_set_header Host $http_host;
}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
说明：
- 加入1个upstream站点进行负载，定义负载均衡设备的Ip及设备状态
- 将3个server中配置proxy_pass代理，格式为：http:// + upstream名称
- weight为权重，即优先运行，数值越大，权重越高
- 每一个请求按访问ip的hash结果分配。这样每一个访客固定访客一个后端服务器，能够解决session的问题
（5）可以修改文件路径C:\Windows\System32\drivers\etc下的hosts文件，进行域名代理测试，示例修改如下
127.0.0.1 localhost
192.168.46.228 www.baidu1.com
192.168.46.228 www.baidu2.com
192.168.46.228 www.baidu3.com
（6）通过浏览器访问地址：
www.baidu1.com:8888/iserver、
www.baidu1.com:8887/iserver、
www.baidu1.com:8886/iserver 等等
均可访问到iserver界面
2、多服务负载（示例：3个nignx拖3个iserver）
配置如下：
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;

server_name 192.168.46.228;
location / {
proxy_pass http://webservers2;
proxy_set_header Host $http_host;
}
}
server {
