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。

-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：
将服务器的rsa私钥下载下来，然后拷贝到自己的机器上。此时必须使用私钥匙登陆才可以成功：-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

apt mariadb-server
/etc/init.d/mysql start
mysql_secure_installation
systemctl start mariadb
systemctl mariadb
systemctl status mariadb
mysql_secure_installation

以下所有操作都是以 root 用户执行
