摘要：開發者工具安裝選擇安裝相關庫的頭文件源命令行需要源磁盤大小查看內存，實用磁盤使用網絡需要源語言安裝安裝然后你需要把以下內容粘貼到文件中安裝安裝然后你需要把以下內容粘貼到文件中文件傳輸安

# 安裝gcc, g++, make, git, svn
yum clean all
yum groups mark install "Development Tools"
yum groups mark convert "Development Tools"
yum groupinstall "Development Tools"

#選擇安裝(相關庫的頭文件)
yum install python-devel libffi-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libxslt-devel libxml2-devel libjpeg-turbo-devel

sudo yum install epel-release

#需要EPEL源

sudo yum install ncdu  #磁盤大小查看
sudo yum install htop atop #內存，CPU實用
sudo yum install iotop #磁盤使用IO
sudo yum install iftop #網絡

#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

>然后你需要把以下內容粘貼到[~/.bash_profile]文件中

# pyenv
PYENV_ROOT="$HOME/.pyenv"

eval "$(pyenv init -)"

pyenv-virtualenvwrapper

#安裝pyenv-virtualenvwrapper
git clone https://github.com/yyuu/pyenv-virtualenvwrapper.git ~/.pyenv/plugins/pyenv-virtualenvwrapper

#安裝virtualenvwrapper
sudo pip install virtualenvwrapper

# 安裝vsftpd
yum install vsftpd

#設置開機啟動vsftpd ftp服務
chkconfig vsftpd on

# 創建nologin用戶
useradd -d /home/ftp -g ftp -s /sbin/nologin ftpuser -p password

修改以下內容/etc/vsftpd/vsftpd.conf

{
    # 禁用匿名登錄
    anonymous_enable=NO
    # 設定支持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
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nginx服務, 此時訪問公有IP, 就能看到歡迎頁面了
systemctl start nginx
service nginx start 

//配置文件位置/etc/nginx/nginx.conf    

安裝

#1.創建/etc/yum.repos.d/mongodb-org-3.0.repo文件內容如下:
[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

sudo systemctl start mysqld

臨時密碼

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

安全配置

sudo mysql_secure_installation

用戶與表權限

 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

這個用起來感覺要簡單一些，而且目前有15,672顆星, 相比第一種擁有資源占用查看，看起來要舒服的多

正常啟動Express項目，也就是
cd <項目目錄>
npm start 或者 node main.js

使用pm2啟動
cd <項目目錄>
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"
