ssh连接
windows打开终端cmd
ssh root@162.241.120.154 -p 22输入密码
网站密码SFTP
使用 FileZilla 软件，主机：sftp://162.241.120.154 用户名：root 密码 网站密码 端口 22
点击快速连接，进去之后点击..返回上一级找到 usr 文件夹。
将修改好的website文件放到 /usr/local/nginx/html 文件夹下（直接拖动，原本的website要先删除，点击..是返回上一级）
修改配置文件（可选）
sudo nano /usr/local/nginx/conf/nginx.conf正常不用修改，两个#的地方保持一致就行
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;# jmbremedy.com www.jmbremedy.com
location / {
root html/website; # 确保路径正确指向您的网站文件
index welcome.html;
}
}
}
重启服务
已经全局添加nginx到path
所以这里在cmd里使用
sudo /usr/local/nginx/sbin/nginx -s reload解决报错
如果打开是空白居多，则是apache服务占用了80端口如下图 [root@162-241-120-154 init.d]# sudo lsof -i :80 后面所示，httpd是apache服务，我们需要停止apache服务 sudo systemctl stop httpd。
[root@162-241-120-154 init.d]# sudo /usr/local/nginx/sbin/nginx -s reload # 先重载nginx发现报错
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

WantedBy=multi-user.targetsudo systemctl daemon-reload
sudo systemctl enable nginx
sudo systemctl start nginxsudo nano /usr/local/nginx/conf/nginx.conf修改
pid /run/nginx.pid;重新启动
sudo systemctl restart nginx查看状态
sudo systemctl status nginx这样以后不需要再用reload，如果以后再遇到nginx自己停止的情况，则需要使用 crontab 实现定时检查与自动启动。
