1、下载文件

nginx下载地址   http://nginx.org/    http://nginx.org/en/download.html

2、安装基本工具

root@localhost ~]#  yum install -y vim lrzsz gcc gcc-c++ make  pcre pcre-devel zlib zlib-devel openssl openssl-devel 

3、创建文件夹上传文件

[root@localhost ~]# mkdir /opt/soft

把下载好的nginx压缩包上传至  /opt/soft  路径下,并解压: “tar zxvf xxx.tar.gz”

4、进入nginx目录(本文实例Nginx-1.15.7)

[root@localhost ~]# cd /opt/soft/nginx-1.15.7

查看文件

5、编译文件

[root@localhost nginx-1.15.7]# ./configure

6、安装

[root@localhost nginx-1.15.7]# make && make install

7、查看已安装好的nginx

[root@localhost ~]# cd /usr/local/nginx/

[root@localhost ~]# ll /usr/local/nginx/

8、启动nginx

[root@localhost ~]# /usr/local/nginx/sbin/nginx

9、查看nginx的启动信息

[root@localhost ~]# ps -ef | grep nginx

10、关闭nginx

[root@localhost ~]# /usr/local/nginx/sbin/nginx -s quit

[root@localhost ~]# /usr/local/nginx/sbin/nginx -s stop

[root@localhost ~]# kill -9 13114  #(13114  是 PID)

[root@localhost ~]# kill -9 13115  #(13115  是 PID)

11、重新加载配置文件

[root@localhost ~]# /usr/local/nginx/sbin/nginx  -s reload

12、启动时加载配置文件的路径:

[root@localhost ~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf  #(配置文件路径)

13、配置nginx

进入安装好的nginx下的conf目录

[root@localhost ~]# cd /usr/local/nginx/conf/

[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf

说明:此处的80即为该nginx的默认端口,可根据自己的需要进行修改

以下为配置Nginx的负责均衡

重新启动nginx,查看

14、关于nginx转发后获取不到客户端真实IP,需要在location里做如下配置

location / {

   proxy_pass http://IP;

   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;
    }

15、nginx 负载均衡配置https 网站,配置文件如下

网站配置完毕后,js、css 等文件找不到报错,需要在location中加一下映射

 # HTTPS server
    #
    server {
        listen       443 ssl;
        listen       10001;
        server_name  localhost;

        ssl   on;
        ssl_certificate      /usr/local/nginx/conf/cert.crt;
        ssl_certificate_key  /usr/local/nginx/conf/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;

            proxy_redirect off;
            proxy_set_header Host $host:10001;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
            proxy_max_temp_file_size 128m;
            proxy_pass https://iosapi;

        }
        location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ {
            proxy_pass https://iosapi;
        }
    }

如图:

16、网站更换CA证书或升级证书 导致nginx转发报错:

 [error] 9126#0: *1791 SSL_do_handshake() failed (SSL: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure) while SSL handshaking to upstream, client: ***, server: localhost, request: "POST /smc/leadership HTTP/1.1", upstream: "https://***:50044/smc/leadership", host: "www.***.com:50043", referrer: "http://****:8002/Home/Index"

解决方案:

在nginx配置文件中的location里加入下面代码:

    proxy_ssl_server_name on;

        proxy_ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

重启nginx服务后即可生效
