Server Maintain Notes

NFS server

NFS server 是用于局域网环境共享linux硬盘的一种方法。关键的配置文 件有：

• /etc/exports （服务端）

/home $CLIENT_IP1_RANGE(rw,sync,no_root_squash,no_subtree_check)
/home $CLIENT_IP2_RANGE(rw,sync,no_root_squash,no_subtree_check)
...

• /etc/fstab （客户端）

$SERVER_IP:/home                /home  nfs defaults  0  0
$SERVER_IP:/home/fileserver     /homes/fileserver  nfs defaults  0  0
...

Nginx

nginx 是轻量级的网站服务，主要的配置文件为：

1. /etc/nginx/nginx.conf, 该文件一般不用修改；

2. /etc/nginx/sites-availble/或/etc/nginx/conf.d/，根据需要增加网站配置问题；

server {
    listen 80;
    listen [::]:80;
 
    server_name domin.com alis www.domin.com;
 
    root /var/www/domin.com;
    index index.html;
 
    location / {
        try_files $uri $uri/ =404;
    }

# 指定文件夹受保护
    location "~^/.*/protected/.*" {
        try_files $uri $uri/ =404;
	auth_basic "Restricted Content";
        auth_basic_user_file /etc/nginx/.htpasswd;
    }
# 指定文件夹中内容按文本文件方式在浏览器中查看
    # 让RFun下文件能在浏览器中直接打开，而不是下载。
    location ~ .*/RFun/.*\..*$ {
       add_header Content-Type text/plain;
    }
}

服务重启方式：sudo /etc/init.d/nginx restart

Shiny server

主要配置文件：/etc/shiny-server/shiny-server.conf

demo conf:

# Instruct Shiny Server to run applications as the user "shiny"
# run_as shiny;
run_as cctdb;

# Define a server that listens on port 3838
server {
  listen 80;

# Only accept requests for the hostname 'server1.com'
  server_name server.domin.com alias IP;

  # Define a location at the base URL
  location / {

    # Host the directory of Shiny Apps stored in this directory
     site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /home/cctdb/shiny;

    # Define the scheduler to use for this location
    simple_scheduler 15;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;
  }
}
server {
  listen 80;

# Only accept requests for the hostname 'server1.com'
  server_name APP1.domain.com;

  # Define a location at the base URL
  location / {

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server/APP1;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # Define the scheduler to use for this location
    simple_scheduler 15;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;
  }
}

服务重启方式：

sudo stop|start|restart shiny-server

Rstudio

主要配置文件为端口配置：

/etc/rstudio/rstudio.conf

服务重启方式：

sudo stop|start|restart rstudio-server
