title:git的ssh连接方式 | ||
--- | ||
|
||
1. 在服务端使用`git init --bare bareDirectory`,或者新建一个`bareDirectory`,然后`cd`进去输入`git init --bare` | ||
**note**:这里面需要使用到`--bare`参数,否则当在客户端提交时,客户端会报错 | ||
``` | ||
remote: error: refusing to update checked out branch: refs/heads/master | ||
remote: error: By default, updating the current branch in a non-bare repository | ||
remote: error: is denied, because it will make the index and work tree inconsistent | ||
remote: error: with what you pushed, and will require 'git reset --hard' to match | ||
remote: error: the work tree to HEAD. | ||
remote: error: | ||
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to | ||
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into | ||
remote: error: its current branch; however, this is not recommended unless you | ||
remote: error: arranged to update its work tree to match what you pushed in some | ||
remote: error: other way. | ||
remote: error: | ||
remote: error: To squelch this message and still keep the default behaviour, set | ||
remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'. | ||
To 121.42.12.48:/home/git/project/testDirectory/ | ||
``` | ||
**上面也提到了可以通过在服务端`git config receive.denyCurrentBranch ignore`来解决,但是不推荐** | ||
|
||
2. 服务端克隆仓库 | ||
``` | ||
git clone [email protected]:/home/git/bareDirectory | ||
git clone ssh://[email protected]:2222/home/git/bareDirectory | ||
# ssh链接方式为 | ||
1, 用户名@IP地址:文件夹绝对路径 (此种方法默认是22端口,:后面的为绝对路径) | ||
2, ssh://用户名@IP地址:端口号+绝对路径 | ||
``` |

title: git免密推送 | ||
--- | ||
|
||
接上文 [linux建立git服务器](https://blog.csdn.net/qq_34111969/article/details/107835545) | ||
下面做一下免密推送 | ||
|
||
全部是客户端操作 | ||
1. 查看公私钥,如果存在,一般在`~/.ssh`目录下面(id_rsa,id_rsa_pub),若不存在,创建之 | ||
```bash | ||
ssh-keygen | ||
``` | ||
2. 上传公钥到服务器 | ||
```bash | ||
ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected] | ||
``` | ||
**说明:** | ||
上面命令其实就是写到服务器的gitpros用户主目录下的`.ssh/authorized_keys`,多个用户可以自动追加到该文件下面,不会覆盖原来用户的公钥 | ||
|
||
3. 测试免密登录 | ||
```bash | ||
ssh [email protected] | ||
``` | ||
*** | ||
**A&Q:** | ||
1. ***免密未成功?*** | ||
一般是服务端的`.ssh`,`.ssh/authorized_keys` 权限有问题 | ||
去服务端使用gitpros账户输入 | ||
```bash | ||
chmod 755 ~/.ssh | ||
chmod 644 ~/.ssh/authorized_keys | ||
``` |

title: 搭建一个git服务器 | ||
--- | ||
1. 首先使用root登录,假设当前服务器ip为123.12.123.12 | ||
2. 新建一个gitpros用户,用来管理所有的代码仓 | ||
```bash | ||
useradd -d /home/gitpros -m gitpros | ||
``` | ||
**说明**: | ||
*username* : linux创建用户命令 | ||
*-d [directory]* : 指定用户主目录,这一步最好加上,会自动添加用户配置文件,如`.bashrc`等文件 | ||
*-m* : 若上面指定的文件夹不存在,则自动创建 | ||
*gitpros* : 要创建的用户名 | ||
|
||
``` | ||
passwd gitpros | ||
``` | ||
**说明**:下面会让设置gitpros的密码,假设为gitpros | ||
|
||
3. 切换到刚创建的gitpros用户(接下来不需要root用户),进入其主目录,创建一个文件夹projects来放所有项目 | ||
```bash | ||
su gitpros | ||
cd /home/gitpros 或者直接 cd ~ | ||
mkdir projects | ||
cd projects | ||
``` | ||
4. 新建一个git服务端代码仓,服务端代码仓一般只用来远程操作,不需要存放实际代码,所以一般会加上`--bare`参数,文件夹结尾一般为.git。 | ||
```bash | ||
git init --bare firstDir.git | ||
``` | ||
**至此服务端工作已经做完了,下面都是客户端所做工作** | ||
*** | ||
|
||
5. 使用git从一台客户端克隆远程仓库 | ||
```bash | ||
git clone [email protected]:/home/gitpros/firstDir.git | ||
``` | ||
期间会让输入密码, 密码为服务端gitpros密码:gitpros | ||
|
||
后面就是基本的add, commit,pull,push的操作了 | ||
|

title: 终端打印文本的颜色 | ||

### 设置打印文本的颜色以及背景色,用来提示错误或者警告; | ||
只需要在打印的字符串中添加"\033[**m",\*\*代表颜色数字。 | ||
```bash | ||
console.log('\033[34m\033[47mno files to show! \n\033[47mfds\n') | ||

title: eslint使用说明 | ||
--- | ||
|
||
## Eslint配置 | ||
|
||
主要是eslint有自己自带的规则,想要禁止或者开启可以在rules里面设置; | ||
|
||
同时可以增加插件,npm install之后要放配置在plugin属性里面, | ||
|
||
增加了插件之后插件会有一些别人写好的规则组,选择一个或者几个写在extends里面,用来开启某一个插件的某些规则。 | ||
|
||
自定义某插件的某一条规则,需要在rules里面设置,设置方式为“插件名称/规则”,例如下面的import插件的“no-unresolved”规则,写成”import/no-unresolved”。 | ||
|
||
Setting里面写的是共享配置, | ||
按照我的理解是vue插件如果也有一条规则叫做“no-unresolved”,本来要在rules里面写两个(“import/no-unresolved”,”vue/no-unresolved”)的。现在在settings里面只需要写”no-unresolved”一个就行了。(以上的settings只是理解,还未验证)(好像是自定义规则而时候才用到,相当于自定义规则可以访问的全局变量,未验证) | ||
|
||
.eslintrc.* 多层级配置文件,会取父子的并集,重复的规则,已离文件最近的为准 | ||
|
||
.eslintignore 类似.gitignore,比它更加严格,使用参数--ignore-path 可以指定ignore文件,如eslint --ignore-path .gitignore file.js | ||
|
||
```js | ||
module.exports = { | ||
env: { | ||
browser: true, //使用browser的规则 | ||
node: true, //使用node的默认规则 | ||
es6: true, //使用es6规则 | ||
}, | ||
"globals": { | ||
"Promise": "off", //不能使用某变量,比如上面开启了es6,加了这个就不能使用Promise变量了 | ||
//比如有时候在window定义了一个变量globalA, globalB, 在模块直接访问他们会报错,只能使用window.globalA, window.globalB | ||
"globalA": "readonly", //只读不可写, 定义了之后可以直接在模块里面使用let a = globalA | ||
"globalB": "writable", //可读可写, 定义了之后可以直接在模块里面使用let b = globalB; globalB = 12 | ||
}, | ||

sourceType: "module", | ||
}, | ||
plugins: [ | ||
"vue", //全局rules使用vue/rule 改写 | ||
"import", //全局rules使用import/rule 改写 | ||
], | ||
extends: [ | ||

//下面所有extend的规则会和下面的全局rules求并集,冲突的属性会以全局rules为准 | ||
"airbnb-base", | ||
"plugin:vue/recommended", | ||
"eslint:recommended", | ||
], | ||
rules: { | ||
//全局rules | ||
//"off" 或 0 - 关闭规则 | ||
//"warn" 或 1 - 开启规则,使用警告级别的错误:warn (不会导致程序退出) | ||
//"error" 或 2 - 开启规则,使用错误级别的错误:error (当被触发的时候,程序会退出) | ||
