Nginx安装使用：webserver及反向代理

rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum repolist
yum install -y nginx

cd /etc/nginx/
openssl req -x509 -nodes -days 36500 -newkey rsa:2048 -keyout nginx.key -out nginx.crt

req是openssl证书请求的子命令
-newkey rsa:2048 -keyout private_key.pem 表示生成私钥(PKCS8格式)
-nodes 表示私钥不加密，若不带参数将提示输入密码
-x509表示输出证书
-days36500 为100年有效期，此后根据提示输入证书拥有者信息
-keyout 代表私钥全路径
-out 代表证书全路径
