nginx配置80端口转发到443

1.0 前提

nginx的https协议需要ssl模块的支持，我们在编译nginx时使用–with-http_ssl_module参数加入SSL模块。还需要服务器私钥，服务器证书，如果是公司对外环境，这个证书需要购买第三方的权威证书，否则用户体验得不到保障；

注意：如果你购买的是第三方服务证书,那么只需要参考1.3-1.4的配置信息即可完整企业ssl配置实践。

1.1检查Nginx的SSL模块是否安装

[root@web-node1 ~]# /application/nginx/sbin/nginx -V

nginx version: nginx/1.6.3

built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)

TLS SNI support enabled

configure arguments: –prefix=/application/nginx-1.6.3 –user=nginx –group=nginx?–with-http_ssl_module?–with-http_stub_status_module

1.2准备私钥和证书

1.2.1创建服务器私钥

[root@web-node1 ~]# cd /application/nginx/conf/
[root@web-node1 conf]# mkdir key
[root@web-node1 conf]# cd key/
[root@web-node1 key]# openssl genrsa -des3 -out server.key 1024
Generating RSA private key, 1024 bit long modulus
..++++++
…++++++
e is 65537 (0x10001)
Enter pass phrase for server.key: ? ? ? ##输入一个密码
Verifying – Enter pass phrase for server.key: ?##再次输入

1.2.2签发证书

[root@web-node1 key]# openssl req -new -key server.key -out server.csr
Enter pass phrase for server.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ‘.’, the field will be left blank.
—–
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:BJ
Locality Name (eg, city) [Default City]:BJ
Organization Name (eg, company) [Default Company Ltd]:SDU
Organizational Unit Name (eg, section) []:SA
Common Name (eg, your name or your server’s hostname) []:XuBuSi
Email Address []:xubusi@xuliangwei.com

Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

1.2.3删除服务器私钥口令

[root@web-node1 key]# cp server.key server.key.ori
[root@web-node1 key]# openssl rsa -in server.key.ori -out server.key
Enter pass phrase for server.key.ori:
writing RSA key

1.2.4生成使用签名请求证书和私钥生成自签证书

[root@web-node1 key]# openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
Signature ok
subject=/C=CN/ST=BJ/L=BJ/O=SDU/OU=SA/CN=XuBuSi/emailAddress=xubusi@xuliangwei.com
Getting Private key

1.3开启Nginx SSL

server {
?
server_name www.123.com;
?
listen ? ? ? 80;
?
rewrite ^(.*) https://$server_name$1 permanent;
}
?
server {
listen 443;
?
server_name www.123.com;
?
ssl on;
?
ssl_certificate key/server.crt;
?
ssl_certificate_key key/server.key;
?
?
?
location / {
?
root ?/application/nginx-1.6.2/html/; ? ##nginx的默认目录
?
index ?index.html index.htm index.php;
?
?
}
?
}

把80端口的访问自动转到443端口

1.4 最后重启nginx服务

/application/nginx/sbin/nginx -s reload
查看端口

netstat -lnp | grep nginx
tcp? ? ? ? 0? ? ? 0 0.0.0.0:80? ? ? ? ? ? ? ? ? 0.0.0.0:*? ? ? ? ? ? ? ? ? ?LISTEN? ? ? 8342/nginx
tcp? ? ? ? 0? ? ? 0 0.0.0.0:443? ? ? ? ? ? ? ? ?0.0.0.0:*? ? ? ? ? ? ? ? ? ?LISTEN? ? ? 8342/nginx
