Linux知识众多，发行版又广，为了避免每次着急使查资料的尴尬情况出现，特此将我平时可能用到的命令都记录下来，以方便后面使用。

/etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list /etc/apt/sources.list

-O /etc/yum.repos.d/CentOS-base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum update

yum makecache

这里我用的是CentOS7的更新源，其他源参考如下：

-O /etc/yum.repos.d/CentOS-base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

Ubuntu/Debian

CentOS

yum gcc

https://blog.csdn.net/vanarrow/article/details/configure install-config

Kali/Ubuntu/Debian

CentOS

chsh -s /bin/zsh

sh -c

clone git://github.com/zsh-users/zsh-autosuggestions /plugins/zsh-autosuggestions

pluginsgit zsh-autosuggestions

zsh

除了安装使用`yum以外，其他配置方法和上面其他发行版系统一样，这里就不再赘述了。

CentOS7安装zsh一些插件和macOS下安装相差不多，这里就简单提一下吧：

autojump

快捷目录跳转插件

在 中配置

输入命令生效配置后即可正常使用命令，下面是简单的演示效果：

$ ~

$ j 2 /root/test/23333

$ /root/test/23333

zsh-syntax-highlighting

命令输入正确会绿色高亮显示，可以有效地检测命令语法是否正确

在 中配置

输入命令生效配置

autosuggestions

终端下自动提示接下来可能要输入的命令，这个实际使用效率还是比较高的

在 中配置

输入命令生效配置

Ubuntu

居然报错了，内容如下：

手动解决依赖，这里是因为openssh-server是依赖于openssh-clien的，那我们手动安装下指定的版本的openssh-client

apt openssh-server

CentOS

Kali/Debian

Ubuntu

systemctl

/etc/init.d/ssh start

CentOS/Debian/Kali

systemctl sshd

systemctl start sshd

/root/.ssh/

id_rsa.pub authorized_keys

/etc/ssh/sshd_config

/etc/init.d/ssh restart

效果如下：

-i ~/Downloads/test_rsa root@10.211.55.9

假设有这样一个场景

想要自己的电脑保存这两台服务器的私钥的话，可以这样配置：

在 目录下创建 文件：

输入以下信息：

Host 2.2.2.2 IdentityFile ~/.ssh/id_rsa_b

然后设置私钥的权限：

/etc/ssh/sshd_config

/etc/init.d/ssh restart

systemctl restart sshd

最基本的连接方式:

FTP连接非默认端口：

或者：

一个完整的登录示例：

目录相关

rname redir delete mdelete

文件上传下载

退出

因为JDK官网需要登录验证才可以下载的原因，不能直接通过wget来下载tar.gz安装包了，得自己手动copy一下。

vim /etc/profile

末尾添加如下内容：

java -version

Centos7 自带Python2版本和pip2，所以我们只要直接安装Python3即可：

yum python36

python3 -V Python 3.6.8

pip3 -V pip 9.0.3 from /usr/lib/python3.6/site-packages python 3.6

pip --upgrade pip pip3 --upgrade pip

pip ipython pip3 ipython

安装pyenv

pyenv Python多版本管理神器，安装起来也很简单：

clone https://github.com/pyenv/pyenv.git ~/.pyenv

”’ ~/.zshrc zsh

基础入门使用可以参考我的这篇文章macOS pyenv入门使用记录

pip3安装

-r --include --include 目标路径

-r --include --exclude /home/sqlsec/Desktop/BBS/

用户名

-r 用户名

apt mysql-server

/etc/init.d/mysql start

mysql_secure_installation

apt mariadb-server

/etc/init.d/mysql start

mysql_secure_installation

systemctl start mariadb

systemctl mariadb

systemctl status mariadb

mysql_secure_installation

FLUSH PRIVILEGES;

以下所有操作都是以 root 用户执行
