# Linux
|
||
|
||
---
|
||
|
||
## 简介
|
||
|
||
在linux系统中，没有盘符的概念。
|
||
一个盘。/根目录
|
||
没有图形化界面
|
||
通过指令操作
|
||
|
||
linux指令是可以传参数的。
|
||
|
||
在Linux系统下，万事万物皆文件。
|
||
|
||
## Linux的文件结构（19个）
|
||
|
||
bin：存放的是二进制的可以执行文件。（重点）
|
||
sbin：存放的是二进制的可以执行文件。super，只有root用户才能访问
|
||
etc：存放系统配置文件（重点）
|
||
usr：用来存放共享的系统资源
|
||
home：家目录（重点）
|
||
root：就是root用户的家目录
|
||
dev：存放设备文件
|
||
|
||
## Linux指令
|
||
|
||
Ctrl+u 删除命令行开始至光标处
|
||
|
||
Ctrl+k 删除光标至命令行结尾
|
||
|
||
Ctrl+a 光标移到最前
|
||
|
||
Ctrl+e 光标移到最后
|
||
|
||
ip addr（ip a）：查看主机的ip地址
|
||
clear：清屏

||
|
||
### 跳转目录：
|
||
|
||
```shell
|
||
# 跳转指定目录 root目录下的www
|
||
cd /root/www

|
||
```
|
||
|
||
|
||
|
||
ls：列出当前目录下的所有文件及目录
|
||
ls -l：给ls指令传了一个参数l。等同于ll。列出当前目录下的所有文件及目录的详情。

||
tar -cf：只打包，不压缩，不显示日志
|
||
tar -xf：解压文件，不显示日志
|
||
tar -cvf：只打包，不压缩，显示日志
|
||
tar -xvf：解压文件，显示日志。

## 查找文件
|
||
|
||
### find 命令
|
||
|

基本格式：find path expression
|
||
|
||
1. 按照文件名查找
|
||
find / -name httpd.conf # 在根目录下 查找文件httpd.conf，表示在整个硬盘查找
|
||
find /etc -name httpd.conf # 在 /etc 目录下查找文件 httpd.conf
|
||
find /etc -name '\*srm*' # 使用通配符\*(0或者任意多个)。表示在 /etc 目录下查找文件名中含有字符串'srm'的文件
|
||
2. 按照文件特征查找
|
||
find / -amin -10 # 查找在系统中最后10分钟访问的文件(access time)
|
||
find / atime -2 # 查找在系统中最后48小时访问的文件
|
||
find / -empty # 查找在系统中为空的文件或者文件夹
|
||
find / -group cat # 查找在系统中属于 group 为 cat 的文件
|
||
find / -mmin -5 # 查找在系统中最后5分钟里修改过的文件(modify time)
|
||
find / -mtime -1 # 查找在系统中最后24小时里修改过的文件
|
||
find / -user fred # 查找在系统中属于fred这个用户的文件
|
||
find / -size +10000c # 查找出大鱼10000字节的文件(c:字节，w:双字, k:KB, M:MB, G:GB)
|
||
find / -size -1000k
|
||
3. 使用混合查找方式查找文件
|
||
参数有：!, -and(-a), -or(-0)
|
||
find /tmp -size +10000c -and -mtime +2 # 在/tmp目录下查找大于10000字节并在最后2分钟内修改的文件
|
||
find / -user fred -or -user george # 在根目录下查找用户是fred或者george的文本文件
|
||
find /tmp ! -user panda #在/tmp目录中查找所有不属于panda用户的文件
|
||
|
||
|
||
|
||
## 进程管理

||
|
||
ps 查看前台进程
|
||
ps -aux 查看所有进程详细信息 UID 用户 PID 进程ID
|
||

### 权限管理
|
||
|
||
Linux 下文件有三种权限 r 读 w写 x可执行
|
||
|
||
---
|
||
|
||
```shell
|
||
chmod 755 file
|
||
```
|
||
|
||
## Shell 脚本
|
||
|
||
### 为什么大多数 shell 脚本都包含 #! /bin/bash 在 shell 脚本的开头？
|
||
|
||
“`#!/bin/bash`”这一行被称为`shebang` 行，在某些文献中，它被称为`hashbang` 行，这是因为它以两个字符`hash '#'` 和`bang '!' `开头。
|
||
|
||
```shell
|
||
#! /bin/bash
|
||
|
||
echo 'Hello, World!'
|
||
```
|
||
|
||
当你在脚本的最顶部包含“`#!/bin/bash`”行时，系统知道你想使用 `bash` 作为脚本的解释器。因此，你现在可以直接运行 `hello.sh` 脚本，而无需在其前面加上 `bash`。
|
||
|
||
使用 `＃！/bin/bash` 表示该脚本是 `bash shell` 脚本，无论系统上正在使用什么 `shell`，都应该使用 `bash` 作为解释器运行。如果你使用的是 `zsh` 特定的语法，你可以通过添加 `#! /bin/zsh` 作为脚本的第一行。
|
||
|
||
`#!` 和 `/bin/bash` 之间的空格无关紧要。你也可以使用 `#!/bin/bash`。
|
||
|
||
## yum
|
||
|
||
### 改阿里源
|
||
|
||
```shell
|
||
yum install -y wget && mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup && wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo && yum clean all && yum makecache
|
||
```
|
||
|
||
## 安装MySQL
|
||
|
||
有些Linux会自带MariaDB数据库，所以需要先卸载
|
||
|
||
列出安装的MariaDB的包
|
||
|
||
```shell
|
||
rpm -qa | grep mariadb
|
||
```
|
||
|
||
得到查看到的包名
|
||
|
||
卸载包 后面加上包名
|
||
|
||
```shell
|
||
rpm -e --nodeps mariadb-libs-5.5.68-1.el7.x86_64
|
||
```
|
||
|
||
自此下载MariaDB已经完成了
|
||
|
||
切换到home目录下
|
||
|
||
```shell
|
||
cd /home/
|
||
```
|
||
|
||
安装 wget 并下载yum库
|
||
|
||
```shell
|
||
yum install wget -y
|
||
wget https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
|
||
rpm -Uvh mysql80-community-release-el7-1.noarch.rpm
|
||
cd /etc/yum.repos.d/
|
||
vim mysql-community.repo
|
||
```
|
||
|
||
选择要安装的MySQL版本
|
||
|
||
```shell
|
||
[mysql57-community]
|
||
name=MySQL 5.7 Community Server
|
||
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
|
||
enabled=0 // 将这里的0改为1
|
||
gpgcheck=1
|
||
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
|
||
|
||
[mysql80-community]
|
||
name=MySQL 8.0 Community Server
|
||
baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/7/$basearch/
|
||
enabled=1 //将这里的1改为0
|
||
gpgcheck=1
|
||
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
|
||
```
|
||
|
||
enabled=0为禁用对应版本的YUM库，enabled=1为启用，默认8.0的配置为enabled=1，安装5.7的话，我们就把8.0的enabled=1修改为enabled=0，然后把5.7的enabled=0修改为enabled=1
|
||
|
||
安装MySQL并启动
|
||
|
||
```shell
|
||
yum install mysql-community-server
|
||
service mysqld start
|
||
```
|
||
|
||
第一步安装成功之后，然后启动MySQL
|
||
|
||
如果失败了，提示GPG
|
||
|
||
RPM 维护一个单独的密钥环，因为它是一个系统范围的应用程序，而用户的 GPG 公钥环是一个用户特定的文件。要将 MySQL 公钥导入 RPM 密钥环，首先获取密钥，然后使用 rpm --import 导入密钥
|
||
|
||
```shell
|
||
# centos
|
||
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
|
||
|
||
# Ubuntu：
|
||
wget -q -O - https://repo.mysql.com/RPM-GPG-KEY-mysql-2022 | apt-key add -
|
||
|
||
yum install mysql-community-server
|
||
```
|
||
|
||
查看MySQL初始密码
|
||
|
||
```shell
|
||
sudo grep 'temporary password' /var/log/mysqld.log
|
||
```
|
||
|
||
登录MySQL
|
||
|
||
```shell
|
||
mysql -u root -p
|
||
```
|
||
|
||
设置密码的验证强度等级
|
||
|
||
```shell
|
||
set global validate_password_policy=LOW;
|
||
```
|
||
|
||
设置密码长度为6位
|
||
|
||
```shell
|
||
set global validate_password_length=6;
|
||
```
|
||
|
||
修改MySQL初始密码
|
||
|
||
```shell
|
||
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
|
||
```
|
||
|
||
给root权限开启远程登录
|
||
|
||
```shell
|
||
use mysql;
|
||
select user,host from user;
|
||
update user set host = '%' where user = 'root';
|
||
flush privileges;
|
||
```
|
||

### AlmaLinux 安装 (dnf包管理器方式)
|
||
|
||
1. 首先确保系统是最新的。
|
||
|
||
```shell
|
||
sudo dnf clean all
|
||
sudo dnf update
|
||
sudo dnf groupinstall "Development Tools"
|
||
```
|
||
|
||
2. 安装 MySQL
|
||
默认情况下，MySQL 在 AlmaLinux 9 基础存储库中可用。 只需使用以下命令安装 MySQL 服务器包 `dnf` 命令：
|
||
|
||
```shell
|
||
sudo dnf install mysql mysql-server
|
||
```
|
||
|
||
设置表名不区分大小写
|
||
|
||
```shell
|
||
vim /etc/my.cnf.d/mysql-server.cnf
|
||
# 在 [mysqld] 中添加
|
||
lower_case_table_names=1
|
||
```
|
||
|
||
初始化后查询是否生效
|
||
|
||
```mysql
|
||
show global variables like '%lower_case%';
|
||
# lower_case_table_names 为 1
|
||
```
|
||
|
||
启动 MySQL 服务并通过运行以下命令使其在启动时自动启动:
|
||
|
||
```shell
|
||
sudo systemctl status mysqld
|
||
sudo systemctl enable --now mysqld
|
||
```
|
||
|
||
确认安装并检查已安装的 MySQL 构建版本：
|
||
```shell
|
||
mysql --version
|
||
```
|
||
|
||
3. 在 AlmaLinux 9 上保护 MySQL。
|
||
默认情况下，MySQL 未加固。 您可以使用 `mysql_secure_installation` 脚本。 您应该仔细阅读以下每个步骤，这些步骤将设置 root 密码、删除匿名用户、禁止远程 root 登录、删除测试数据库和访问安全 MySQL：
|
||
|
||
```shell
|
||
mysql_secure_installation
|
||
```
|
||
|
||
对提示使用以下选项：
|
||
```shell
|
||
Enter current password for root (enter for none): Just press the Enter
|
||
Set root password? [Y/n]: Y
|
||
New password: Enter your password
|
||
Re-enter new password: Repeat your password
|
||
Remove anonymous users? [Y/n]: Y
|
||
Disallow root login remotely? [Y/n]: Y
|
||
Remove test database and access to it? [Y/n]: Y
|
||
Reload privilege tables now? [Y/n]: Y
|
||
```
|
||
|
||
安全后，您可以使用以下命令登录 MySQL shell:
|
||
```shell
|
||
sudo mysql -u root -p
|
||
```
|
||
|
||
要创建数据库、数据库用户并向数据库用户授予所有权限，请运行以下命令：
|
||
```mysql
|
||
CREATE DATABASE test_db;
|
||
CREATE USER 'test_user'@'localhost' IDENTIFIED BY 'your-password';
|
||
GRANT ALL ON tests_db.* TO 'test_user'@'localhost';
|
||
FLUSH PRIVILEGES;
|
||
EXIT
|
||
```
|
||
|
||
|
||
### AlmaLinux 安装 (rpm手动方式)
|
||
|
||
```shell
|
||
mkdir mysql_install
|
||
cd mysql_install

|
||
|
||
移除 `/dev/mapper/almalinux-home`(删除前请确保重要文件已备份)
|
||
|
||
```shell
|
||
lvremove /dev/mapper/almalinux-home
|
||
```
|
||
|
||
|
||
|
||
```shell
|
||
lsblk
|
||
```
|
||
|
||
|
||
|
||
扩展`/dev/mapper/almalinux-root`增加8.7G
|
||
|
||
```shell
|
||
lvresize -L +8.7G /dev/mapper/almalinux-root

|
||
```
|
||
|
||
|
||
|
||
挂载
|
||
|
||
**因为lv名称和挂载点不变，因此无需修改/etc/fstab**
|
||
|
||
```shell

||
|
||
#### 新加卷
|
||
|
||
Orale VirtualBox
|
||
|
||
|
||
|
||
需要选择最后一个，因为前几个是之前的备份快照
|
||
|
||
|
||
|
||
分配大小即可，只能增加不能缩小
|
||
|
||
查看现有分区大小
|
||
|
||
```shell
|
||
df -Th
|
||
```
|
||
|
||
|
||
|
||
查看扩容后磁盘大小
|
||
|
||
```shell
|
||
lsblk
|
||
```
|
||
|
||
|
||
|
||
创建分区
|
||
|
||
```shell
|
||
fdisk /dev/sda
|
||
```
|
||
|
||
|
||
|
||
|
||
|
||
刷新分区并创建物理卷
|
||
|
||
```shell
|
||
partprobe /dev/sda
|
||
pvcreate /dev/sda4
|
||
```
|
||
|
||
|
||
|
||
查看卷组名称，以及卷组使用情况
|
||
|
||
```shell
|
||
vgdisplay
|
||
```
|
||
|
||
|
||
|
||
将物理卷扩展到卷组
|
||
|
||
```shell
|
||
vgextend rl /dev/sda4
|
||
```
|
||
|
||
|
||
|
||
查看当前逻辑卷的空间状态
|
||
|
||
```shell
|
||
lvdisplay
|
||
```
|
||
|
||
|
||
|
||
将卷组中的空闲空间扩展到根分区逻辑卷
|
||
|
||
```shell
|
||
lvextend -l +100%FREE /dev/rl/root
|
||
```
|
||
|
||
|
||
|
||
刷新根分区
|
||
|
||
```shell
|
||
xfs_growfs /dev/rl/root
|
||
```
|
||
|
||
|
||
|
||
扩容成功
|
||
|
||
|
||
|
||
## 分配Swap
|
||
|
||
查看分区大小
|
||
|
||
```shell
|
||
free -h
|
||
```
|
||
|
||
使用dd命令创建一个swap分区
|
||
|
||
```shell
|
||
dd if=/dev/zero of=/home/swap bs=1024 count=4194304
|
||
```
|
||
|
||
count的值是：size（多少M）* 1024
|
||
|
||
格式化swap分区
|
||
|
||
```shell
|
||
mkswap /home/swap
|
||
```
|
||
|
||
把格式化后的文件分区设置为swap分区
|
||
|
||
```shell
|
||
swapon /home/swap
|
||
```
|
||
|
||
swap分区自动挂载
|
||
|
||
```shell
|
||
vim /etc/fstab
|
||
# G 在文件末尾加上
|
||
/home/swap swap swap default 0 0
|
||
```
|
||
|
||
关闭Swap
|
||
|
||
```shell
|
||
swapoff /home/swap
|
||
```
|
||
|
||
### 修改swap使用率
|
||
|
||
swappiness的值的大小对如何使用swap分区是有着很大的联系的。swappiness=0的时候表示最大限度使用物理内存，然后才是 swap空间，swappiness＝100的时候表示积极的使用swap分区，并且把内存上的数据及时的搬运到swap空间里面。两个极端
|
||
|
||
查看swappiness
|
||
|
||
```shell
|
||
cat /proc/sys/vm/swappiness
|
||
```
|
||
|
||
修改swappiness值为60
|
||
|
||
```shell
|
||
sysctl vm.swappiness=60
|
||
```
|
||
|
||
但是这只是临时性的修改，还要做一步
|
||
|
||
```shell
|
||
vim /etc/sysctl.conf
|
||
# 编辑这行
|
||
vm.swappiness=60
|
||
```
|
||
|
||
## Windows Linux子系统
|
||
|
||
### WSL2
|
||
|
||
打开 Windows Terminal PowerShell
|
||
|
||
#### 安装
|
||
|
||
```powershell
|
||
wsl --install
|
||
```
|
||
|
||
微软官方文档 [安装 WSL | Microsoft Docs](https://docs.microsoft.com/zh-cn/windows/wsl/install)
|
||
|
||
默认安装Ubuntu 20.04 LTS版
|
||
|
||
更改默认安装的Linux发行版
|
||
|
||
```powershell
|
||
wsl --install -d <Distribution Name>
|
||
```
|
||
|
||
/mnt目录下是Windows系统的挂载盘，可直接访问Windows磁盘文件
|
||
|
||
#### 通过FinalShell连接WSL2
|
||
|
||
1. 需要先删除ssh，再安装ssh
|
||
|
||
```shell
|
||
apt-get remove --purge openssh-server #先删ssh
|
||
apt-get install openssh-server #再安装ssh
|
||
rm /etc/ssh/ssh_config
|
||
service ssh --full-restart #重启ssh服务
|
||
```
|
||
|
||
2. 修改配置文件
|
||
|
||
```shell
|
||
vim /etc/ssh/sshd_config
|
||
|
||
Port 6666 # 指定连接端口 6666
|
||
ListenAddress 0.0.0.0 # 指定连接的IP
|
||
PasswordAuthentication yes # 开启密码认证
|
||
PermitRootLogin yes # 开启root用户登录
|
||
|
||
```
|
||
|
||
3. 重启ssh（每次重启wsl都要执行该语句）
|
||
|
||
```shell
|
||
service ssh --full-restart
|
||
```
|
||
|
||
4. 重新生成host key
|
||
|
||
```shell
|
||
dpkg-reconfigure openssh-serve
|
||
```
|
||
|
||
FinalShell就可以连接WSL2了
|
||
|
||
#### 启用systemctl
|
||
|
||
进入当前发行版
|
||
|
||
编辑 /etc/wsl.conf
|
||
|
||
```shell
|
||
vim /etc/wsl.conf
|
||
# 内容如下
|
||
[boot]
|
||
systemd=true
|
||
```
|
||
|
||
重启WSL
|
||
|
||
```powershell
|
||
wsl --shutdown
|
||
```
|
