nginx+acme申请证书

1. centos上执行以下命令

yum update #更新服务器一些依赖
yum install nginx #安装Nginx
nginx -c /etc/nginx/nginx.conf #执行这句之后reload不会报错
vim /etc/nginx/nginx.conf #打开nginx配置文件
#把里面的 server_name 改为你想要的域名
#下面继续安装acme
curl  https://get.acme.sh | sh #如果卡的话 ctrl+c 取消再执行，多试几次
cd ~/.acme.sh
./acme.sh --issue -d mydomain.com --nginx #替换mydomain.com为你的域名
#成功后会显示证书的路径，这里我们只需要 mydomain.key 和 fullchain.cer 把这两个的路径复制到nginx.conf上就配置成功了	

下面是nginx.conf的配置示例 以强制跳转https
