Nginx自签证书配置HTTPS协议访问

组件	版本
OS	CentOS 7.5
nginx	1.14.1-9

安装nginx

yum install epel-release
yum install nginx
systemctl start nginx

firewalld

如果有防火墙策略的需求的话,没有的话跳过：

# 允许http和https服务
sudo firewall-cmd --add-service=http
sudo firewall-cmd --add-service=https
sudo firewall-cmd --runtime-to-permanent
# 允许 80（http）,443(https) 端口
sudo iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT
sudo iptables -I INPUT -p tcp -m tcp --dport 443 -j ACCEPT

生成证书

新建证书目录

mkdir /etc/ssl/private
sudo chmod 700 /etc/ssl/private

生成X509证书

openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
-keyout /etc/ssl/private/signed.key -out /etc/ssl/certs/signed.crt

其中：

• signed.key: RSA私钥
• signed.crt: 证书

参数解释：
req: openssl子命令,使用X.509是一项公钥基础设施行业标准，SSL/TLS遵从这个标准。
-keyout : 私钥输出路径
-out: 证书输出路径

然后命令执行后需要输入一些证书信息：

Country Name (2 letter code) [AU]: 直接回车
State or Province Name (full name) [Some-State]:直接回车
Locality Name (eg, city) []:直接回车
Organization Name (eg, company) [Internet Widgits Pty Ltd]:直接回车
Organizational Unit Name (eg, section) []:直接回车
Common Name (e.g. server FQDN or YOUR name) []:输入IP
Email Address []:[email protected]

配置nginx配置文件

编辑/etc/nginx/nginx.conf,我的文件是这样的：

    }

}

重启nginx: systemctl restart nginx

访问测试

一开始会提示不安全，直接详情->继续，就看到https页面可以访问。之后就不会提示了。
