sudo yum install ncdu  #磁盤大小查看
sudo yum install htop atop #內(nèi)存，CPU實(shí)用
sudo yum install iotop #磁盤使用IO
sudo yum install iftop #網(wǎng)絡(luò)

#需要EPEL源

sudo yum install nodejs

pip

#安裝pip
$ wget https://bootstrap.pypa.io/get-pip.py
$ python ./get-pip.py

pyenv

#安裝pyenv
curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash

# 安裝vsftpd
yum install vsftpd

#設(shè)置開機(jī)啟動(dòng)vsftpd ftp服務(wù)
chkconfig vsftpd on

# 創(chuàng)建nologin用戶
useradd -d /home/ftp -g ftp -s /sbin/nologin ftpuser -p password

修改以下內(nèi)容/etc/vsftpd/vsftpd.conf

{
    # 禁用匿名登錄
    anonymous_enable=NO
    # 設(shè)定支持ASCII模式的上傳和下載功能
    ascii_upload_enable=YES
    ascii_download_enable=YES
    
    只允許剛創(chuàng)建的ftpuser登錄FTP
    userlist_enable=YES
    userlist_deny=NO
}

#修改 /etc/vsftpd/user_list
注釋所有帳戶，添加ftpuser

#重啟服務(wù)
service vsftpd restart                        

#登錄
ftp dean@IP地址

//下載nginx到/tmp
curl -o /tmp/nginx.rpm http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm 

//安裝rpm, 此rpm包含yum配置信息
rpm -ivh /tmp/nginx.rpm  

//安裝nginx
yum install nginx 

//2選1, 啟動(dòng)nginx服務(wù), 此時(shí)訪問(wèn)公有IP, 就能看到歡迎頁(yè)面了
systemctl start nginx
service nginx start 

//配置文件位置/etc/nginx/nginx.conf    

安裝

#1.創(chuàng)建/etc/yum.repos.d/mongodb-org-3.0.repo文件內(nèi)容如下:
[mongodb-org-3.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.0/x86_64/
gpgcheck=0
enabled=1

#2.運(yùn)行
sudo yum install -y mongodb-org

安裝

sudo yum update

wget http://repo.mysql.com//mysql57-community-release-el7-8.noarch.rpm
sudo rpm -ivh mysql57-community-release-el7-8.noarch.rpm
sudo yum update

sudo yum install mysql-server

啟動(dòng)

sudo systemctl start mysqld

臨時(shí)密碼

sudo grep "temporary password" /var/log/mysqld.log

安全配置

sudo mysql_secure_installation

用戶與表權(quán)限

 create database testdb;
 create user "testuser"@"localhost" identified by "password";
 grant all on testdb.* to "testuser" identified by "password";

重置密碼

sudo systemctl stop mysqld
sudo systemctl set-environment MYSQLD_OPTS="--skip-grant-tables"
sudo systemctl start mysqld

mysql -u root

use mysql;
update user SET PASSWORD=PASSWORD("password") WHERE USER="root";
flush privileges;
exit

sudo systemctl stop mysqld
sudo systemctl unset-environment MYSQLD_OPTS
sudo systemctl start mysqld

#安裝
sudo pip install pyOpenSSL
sudo pip install lxml
sudo pip install scrapyd

這個(gè)用起來(lái)感覺(jué)要簡(jiǎn)單一些，而且目前有15,672顆星, 相比第一種擁有資源占用查看，看起來(lái)要舒服的多

正常啟動(dòng)Express項(xiàng)目，也就是
cd <項(xiàng)目目錄>
npm start 或者 node main.js

使用pm2啟動(dòng)
cd <項(xiàng)目目錄>
pm2 start npm --name="express" -- start

python命令:
scrapyd --pidfile /var/log/scrapyd/twistd.pid -l /var/log/scrapyd/logs/scrapyd.log

pm2命令:
pm2 start scrapyd --interpreter python --name=scrapyd -- --pidfile "/var/log/scrapyd/twistd.pid" -l "/var/log/scrapyd/logs/scrapyd.log"
