介绍

我是一个前端工程师，对于后端还算是个新手，下面是我手机的一些关于阿里云Centos7使用的一些工具，希望对你有帮助。

开发者工具

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

#选择安装(相关库的头文件)
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

EPEL源

sudo yum install epel-release

任务管理器

#需要EPEL源

sudo yum install ncdu  #磁盘大小查看
sudo yum install htop atop #内存，CPU实用
sudo yum install iotop #磁盘使用IO
sudo yum install iftop #网络

Node.js:

#需要EPEL源

sudo yum install nodejs

Python语言

pip

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

pyenv

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

>然后你需要把以下内容粘贴到[~/.bash_profile]文件中

# pyenv
PYENV_ROOT="$HOME/.pyenv"
PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"

pyenv-virtualenvwrapper

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

    #安装virtualenvwrapper
    sudo pip install virtualenvwrapper

    >然后你需要把以下内容粘贴到~/.bash_profile文件中

    #pyenv virtualenvwrapper
    pyenv virtualenvwrapper_lazy

文件传输

语法: scp 用户名@地址:{from} {to}

scp [email protected]:/home/sirius/articles.csv .
scp ./articles.csv [email protected]:/home/sirius/

nginx服务

# 下载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

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

# 安装nginx
yum install nginx

# 2选1, 启动nginx服务, 此时访问公有IP, 就能看到欢迎页面了
systemctl start nginx
service nginx start

# 配置文件位置/etc/nginx/nginx.conf

mongoDB数据库

# 1. 创建/etc/yum.repos.d/mongodb-org-3.0.repo文件内容如下:
[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.运行
sudo yum install -y mongodb-org

MySQL

安装

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

启动 sudo systemctl start mysqld

临时密码 sudo grep 'temporary password' /var/log/mysqld.log

安全配置 sudo mysql_secure_installation

用户与表权限

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

重置密码

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

Scrapyd

sudo pip install pyOpenSSL
sudo pip install lxml
sudo pip install scrapyd

PM2:

# 正常启动Express项目，也就是
cd <项目目录>
npm start` 或者 `node main.js

# 使用pm2启动
cd <项目目录>
pm2 start npm --name='express' -- start

其他语言:

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"

docker

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

sudo yum install docker-ce

# start
sudo systemctl start docker

# test
sudo docker run hello-world
