ssh 开 root登录

1. 查看ssh服务器是否安装并启动

1. 
   
2. #sudo ps -e | grep ssh
   

复制代码

1. 安装ssh服务器

1. #sudo apt-get install openssh-server

复制代码

2. 配置sshd文件
编辑SSH服务的配置文件sshd_config，修改SSH的端口和root用户权限。

使用到的命令：（按字母“i”进入编辑模式，按ESC退出编辑模式，“:wq”保存退出）。

root@dante:~# vim /etc/ssh/sshd_config
1、找到# port 22所在的那一行，复制该行内容并修改。

将“#port 22”修改为“port 22”（将前面的“#”去掉）。

该行内容为设置SSHd服务的端口号

2、找到#PermitRootLogin prohibit-password那一行，复制该行内容并修改。

1. 
   
2. 将“#PermitRootLogin prohibit-password”修改为“PermitRootLogin yes”
   

复制代码

3. 重启服务器 service ssh restart

1. service ssh restart

复制代码

---- nginx 常用命令
/etc/init.d/nginx restart
nginx -s reload  ：修改配置后重新加载生效




------------------------

安装nginx扩展
apt -y install nginx-core
apt -y install nginx-extras
apt -y install nginx-full
apt -y install nginx-light

nginx: [error] open() "/run/nginx.pid" failed (2: No such file or directory)

nano /etc/nginx/conf/nginx.conf
#pid        logs/nginx.pid;
下面增加
/etc/nginx/logs/nginx.pid;


/etc/init.d/nginx restart
nginx -s reload  ：修改配置后重新加载生效

centos7
https://www.cnblogs.com/kaerxifa/p/11713199.html

启动nginx服务
systemctl start nginx.service

停止nginx服务
systemctl stop nginx.service

重新启动服务
systemctl restart nginx.service

重新读取nginx配置(这个最常用, 不用停止nginx服务就能使修改的配置生效)
systemctl reload nginx.service
