Nginx配置使用详解(图文真棒)

1、启动nginx
    ./nginx
2、关闭nginx
 ./nginx -s stop
3、重新加载nginx (nginx.conf)
 ./nginx -s reload
4、查看版本号
 ./nginx -v

# 可以配置多个server块 

}

#这一行表示这个server块监听的端口是80，只要有请求访问了80端口，此server块就处理请求
listen       80;
#  表示这个server块代表的虚拟主机的名字
server_name  localhost;

# 表示如果请求路径是/就是用这个location块进行处理
location / {
            root   html;
            index  index.html index.htm;
        }

server {
# 监听端口80 即当访问服务器的端口是80时，进入这个server块处理
        listen       80;
# server_name当配置了listen时不起作用        
        server_name  localhost;

# location后面代表访问路径 当是/ 请求时 代理到tomcat的地址
        location / {
# 使用 proxy_pass（固定写法）后面跟要代理服务器地址            
            proxy_pass http://192.168.80.102:8080;
        }
}

server {
# 监听9001端口
        listen       9001;
# 进行路径匹配，匹配到edu代理到8081
        location ~/edu/ {
            proxy_pass http://192.168.80.102:8081;
        }
# 进行路径匹配，匹配到vod代理到8082
        location ~/vod/ {
            proxy_pass http://192.168.80.102:8082;
        }
}

# 在http块中的全局块中配置
# upstream固定写法 后面的myserver可以自定义
upstream myserver{
    server 192.168.80.102:8081;
    server 192.168.80.102:8082;

# server配置
    server {
      # 监听80端口
        listen 80;   
     #location块
        location / {
# 反向代理到上面的两台服务器 写上自定义的名称

    # 当访问路径带了www时，进入这个location处理，去/staticResource目录下对应的www目录     去找okc.html
