傷城~ 2021-10-25 15:14 413阅读 0赞

1、到Nginx官网下载相应版本的Nginx  nginx-1.12.1.tar.gz

2、解压到 　　/usr/local/nginx-1.12.1

3、建立软链 ln -s /usr/local/nginx-1.12.1/  /usr/local/nginx

4、进入/usr/local/nginx/conf目录

![1495707-20180921144121532-1773602578.png][]

vim 打开nginx.conf

在http\{

.......

include inc/\*.conf;  
 　　include include/\*.conf;

\}底部添加红色代码，

内容如下：注意红色部分

#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 {
    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;
    # }
    #}
    include inc/*.conf;
    include include/*.conf;
    }

5、到 /usr/local/nginx/conf/ 目录下创建 两个文件夹 Inc include

6、进入 Inc 添加你所需要的基本配置

![1495707-20180928113924160-69894937.png][]

fastcgi.conf

##fastcgi
        fastcgi_connect_timeout 30;
        fastcgi_send_timeout 60;
        fastcgi_read_timeout 60;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 8 256k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_temp_file_write_size 256k;
        fastcgi_intercept_errors on;
    
    upstream php_backend  {
            server 127.0.0.1:1026;
    }

gzip.conf

## Compression
        gzip                on;
        ##gzip_static         on;
        gzip_min_length     1024;
        gzip_buffers        16 8k;
        gzip_http_version   1.1;
        gzip_comp_level     9;
        gzip_types          text/plain text/css application/x-javascript application/x-amf text/xml application/xml application/rss+xml text/javascri
    pt image/gif image/jpeg image/png image/tiff image/x-icon image/x-ms-bmp application/pdf application/x-shockwave-flash application/vnd.wap.xhtml+
    xml;
        gzip_vary           on;

logs.conf

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for" '
              '"$host" "$server_port" $request_time';
    
    access_log  /home/logs/nginx/access_log  main;
    error_log  /home/logs/nginx/error_log;

ssl.conf

#ssl                on;
    #ssl_certificate        certs/myssl.crt;
    #ssl_certificate_key        certs/myssl.key;
    #ssl_ciphers            "HIGH:!aNULL:!MD5:!EXPORT56:!EXP";
    ## ssl_ciphers            "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RS
    A-AES256-SHA:ECDHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DE
    S-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";
    #ssl_protocols            TLSv1 TLSv1.1 TLSv1.2;
    #ssl_prefer_server_ciphers    on;
    #ssl_session_cache        shared:SSL:10m;
    #ssl_session_timeout        5m;

7、进入 /usr/local/nginx/conf/include 进行代理配置

![1495707-20180928114422788-1722141508.png][]

8、具体打单个proxy.conf

upstream www_xiaoga_cn {
        server 127.0.0.1:8100 max_fails=3 fail_timeout=30s;
        server 127.0.0.1:8200 max_fails=3 fail_timeout=30s;
        }
    server {
            listen 80;
            server_name www.xiaoga.cn;
            access_log  /home/logs/nginx/www.xiaoga.cn/access_log main;
            error_log  /home/logs/nginx/www.xiaoga.cn/error_log;
            log_not_found on;
            location / {
                    proxy_pass http://www_xiaoga_cn;
                    proxy_set_header Host $host:$server_port;
                    proxy_set_header X-Real-IP $remote_addr;
                    proxy_set_header X-Real-PORT $remote_port;
                    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_connect_timeout 300;
                proxy_send_timeout 300;
                proxy_read_timeout 600;
                proxy_buffers 4 256k;
                proxy_busy_buffers_size 256k;
                proxy_temp_file_write_size 256k;
                proxy_next_upstream error timeout invalid_header http_502 http_503 http_504;
                proxy_max_temp_file_size 128m;
            }
    }

==================================================

由于每一个proxy.conf都是大度的一个配置文件，不担心配置时出错而影响其他代理配置

9、启动两个Tomcat服务8100 8200

由于域名是假的需要配置host，host配置不多讲，自行百度

测试：

到此实现了一个简单的负载均衡，over！
