nginx: 400 Bad Request | The plain HTTP request was sent to HTTPS port

nginx版本1.0.4 

nginx一般情况下配置;
server {
listen 443;
server_name localhost;
ssl on;
root html;
index index.html index.htm;
ssl_certificate cert/214525134250577.pem;
ssl_certificate_key cert/214525134250577.key;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
root html;
index index.html index.htm;
}
}然后神器的一幕发生了，首先是： nginx: [warn] invalid value "TLSv1.1"  nginx: [warn] invalid value "TLSv1.2"
把 TLSv1.1 TLSv1.2 删掉；报错  nginx: 400 Bad Request | The plain HTTP request was sent to HTTPS port



参考官方文档解决如下：server {
listen 80;
server_name localhost;
root html;
index index.html index.htm;

listen 443 ssl; #注意这里
#ssl on;
ssl_certificate cert/214525134250577.pem;
ssl_certificate_key cert/214525134250577.key;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1;
ssl_prefer_server_ciphers on;

location / {
root html;
index index.html index.htm;
}
}删掉 ssl on; 并在 listen 443; 后面加上ssl即可
