nginx根据域名做http,https分发

omcat端口:8080 做好虚拟主机 参照我的另一篇文章
nginx端口:80 根据域名分派

在conf/nginx.conf中的http中增加

include www.huozhe.com.conf

新建conf/www.huozhe.com.conf,内容如下:

server {
listen 80;
server_name www.huozhe.com;

location / {
    proxy_pass http://127.0.0.1:8080;
    proxy_set_header Host $host:80;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Via "nginx";
}
}

其中127.0.0.1是你的tomcat主机ip

要是代理https的话,内容如下:

server {
listen 443;
server_name mail.huozhe.com;

ssl on;
ssl_certificate server.crt;
ssl_certificate_key server.key;

location / {
    proxy_pass https://192.168.0.2:443;
    proxy_set_header Host $host:443;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Via "nginx";

}
}

 

其中192.168.0.2是你的https主机
如果后端https没有证书的话,可以如此简化:

server {
listen 80;
server_name svn.huozhe.com;

location / {
    proxy_pass https://192.168.0.2:443;
    proxy_set_header Host $host:443;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Via "nginx";
    proxy_set_header X-Forwarded-Proto https; #注意看这里 多了一行
}
}

 

如果提示“SSL 接收到一个超出最大准许长度的记录。”  错误代码“ssl_error_rx_record_too_long”说明少了“ssl on;”这一行

后面的server.crt server.key是数字证书,具体可以参照openssl做证书

openssl做证书================================================

mkdir ssl
cd ssl
openssl genrsa -des3 -out server.key 1024 # 会提示你输入key,尽可能长些复杂些,后面好几处要用,我都是复制粘贴的
openssl req -new -key server.key -out server.csr # 输入组织信息 CN BeiJing HaiDian huozhe.com
cp server.key server.key.org
openssl rsa -in server.key.org -out server.key
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

 

这里的server.crt server.key你就可以拿去用了
