Nginx如何設定ssl實作https

一、安裝Nginx ssl 模組

1.檢查

檢查是否已安裝ssl 模組：

cd /usr/local/nginx/sbin
./nginx -V

[root@server-c00ef8c3-710d-4708-9cde-2c864e7c03e2 sbin]# ./nginx -V
nginx version: nginx/1.21.4
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
configure arguments: --prefix=/usr/local/nginx

如果沒出現configure arguments: --with-http_ssl_module 說明沒有安裝。

2.安裝

cd /usr/local/nginx-1.21.4
./configure --prefix=/usr/local/nginx --with-http_ssl_module
make
cp ./objs/nginx /usr/local/nginx/sbin/

3.再次檢查

再次檢查是否已安裝ssl 模組：

cd /usr/local/nginx/sbin
./nginx -V

[root@server-c00ef8c3-710d-4708-9cde-2c864e7c03e2 sbin]# ./nginx -V
nginx version: nginx/1.21.4
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module

二、部署ssl 憑證

將申請好的ssl 憑證拷貝至cert 目錄下：

三、設定nginx.conf

cd /usr/local/nginx/conf
vi nginx.conf

新增https server 設定：

#管理端https
server {
     listen 443 ssl;
     server_name admin-xxxxx.xxx.xxx;
     ssl_certificate ../cert/server.crt;
     ssl_certificate_key ../cert/server.key;
     ssl_session_timeout 5m;
     ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
     ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
     ssl_prefer_server_ciphers on;

     location / {
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header Host $http_host;
         proxy_pass http://localhost:10003;
     }
}

四、重啟Nginx

/usr/local/nginx/sbin/nginx -s reload

或

ps -ef|grep nginx
kill xxx
/usr/local/nginx/sbin/nginx

補充：如果80 連接埠被佔用，用kill [id]來結束進程：

# 查看端口使用
$ netstat -lntp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 0.0.0.0:80 0.0.

##tcp 0 0 0.0.0.0:80 0.0.0.0 : LISTEN 21307/nginx: master

tcp 0 0 0.0.0.0:22 0.0.0.0: LISTEN 3072/sshd

tcp 0 0 0.0.0.0:443 0.0.0

tcp 0 0 0.0.0.0:443 0.0.0. LISTEN 21307/nginx: master

結束80 埠程序

$ kill 21307

###再次重啟nginx ：###

$ /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
