nginx学习

1、centos7下安装nginx

首先去nginx官网https://nginx.org/下载对应的版本

安装nginx所需要的依赖

yum -y install pcre-devel 
yum -y install openssl openssl-devel

解压nginx压缩包

 tar -zxvf nginx-1.18.0.tar.gz

进入解压后的目录，进行检查、编译、安装，执行如下命令：

./configure
make
make install

2、nginx启动、关闭、重启

配置文件在conf目录下的nginx.conf文件

静态页面为html目录下的静态页面

#进入sbin目录下
./nginx			#启动
./nginx -s reload 	#重新加载配置
./nginx -s stop		#关闭
./nginx -s quit		#优雅地退出

3、nginx配置反向代理

参考的配置文件

#参考的完整配置文件
#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;
}


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;
	#改配置为配置一个项目的情况下配置反向代理
    server {
        listen       80;			#监听的端口
        server_name  localhost;		#服务器名称

        location ~ /mytest/ {		#当请求路径包含有/mytest/的时候会请求http://192.168.17.128:8080
            
			proxy_pass http://192.168.17.128:8080;
            
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;		#错误页面
        location = /50x.html {						
            root   html;								#错误页面在当前配置文件的上一级html目录下
        }

        # 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;
    #    }
    #}

}

配置两个项目：

配置的监听本地的端口为80，服务器名字为本地的ip地址

当请求路径中包含/m/，就会去请求http://192.168.17.1:8080;

当请求路径中包含/n/，就会去请求http://192.168.17.1:8081;

创建两个springboot项目

端口号为8081

端口号为8080

centos7防火墙

systemctl status firewalld			#防火墙状态
systemctl stop 	firewalld			#关闭防火墙
systemctl	start	firewalld		#开启防火墙

firewall-cmd --list-all				#查看开启的端口号
firewall-cmd --list-ports			#查看开启的端口号

firewall-cmd --zone=public --add-port=8080/tcp --permanent			#开启端口
参数含义：
--zone #作用域
--add-port=80/tcp #添加端口，格式为：端口/通讯协议
--permanent #永久生效，没有此参数重启后失效
