邮件发送（shell）
由于服务器运营商已经封杀了25端口，那么一种方法是：通过465发送邮件到其他邮件服务商
安装邮箱配置
yum install mailx -ymailx配置
vi /etc/mail.rc# wkj config
set smtp="smtps://smtp.exmail.qq.com:465"
set from=发送的邮箱（与smtp-auth-user必须一致）
set smtp-auth=login
set smtp-auth-user=发送的邮箱（与from必须一致）
set smtp-auth-password=授权密码
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb测试发送
echo 内容 | mailx -v -s 主题 -a 附件 接收邮箱运维日记
查看杀进程
egrep -i -r 'killed' /var/log
删除找到的所有png
find ./ -name '*.png' | xargs rm -f
docker 重新启动
systemctl restart docker
docker-compose 启动
docker-compose up -d
docker-compose 停止
docker-compose down
docker 进入容器
docker exec -it 容器名 bash
docker 运行日志
docker logs --tail="10" 容器名

Git命令（官方网站： https://git-scm.com/docs）
删除远程仓库的地址
$ git remote rm origin
重置到提交 (恢复到f4df19d提交)
$ git reset --hard f4df19d
重置到远程自己最后一次提交（有可能会抹掉别人的提交）
$ git push origin HEAD --force
取消上一次本地提交（同时清空提交的内容）
$ git reset HEAD~ && git checkout . && git clean -xdf
清除本地提交
$ git reset --hard FETCH_HEAD
清除缓存区所有的内容（不包含本地提交）
$ git checkout . && git clean -xdf添加远程地址(比如远程地址：git@git.kjwoo.cn:bowen/test.git)
$ git remote add origin git@git.kjwoo.cn:bowen/test.git
修改远端地址
$ git remote set-url origin xxx使用yum安装git2.X（wandisco的yum源）
[root@wkjhost ~]# yum install http://opensource.wandisco.com/centos/7/git/x86_64/wandisco-git-release-7-1.noarch.rpm
[root@wkjhost ~]# yum install gitgit push到远程分支时报错error: RPC failed; HTTP 411 curl 22 The requested URL returned error: 411 Length Req
git config http.postBuffer 524288000清理本地存储
$ git gc --prune=now
$ git remote prune origin使用合并策略
git config --global pull.rebase true
git config --global branch.autoSetupRebase always标签
//创建标签
git tag -a 标签名字 -m "标签注释"
//推送所有的分支到远端
git push origin --tagssourcetree 还原配置
确保SourceTree已关闭。
确保在删除文件之前在以下文件夹中备份文件
删除~/Library/Application Support/SourceTree/
中的所有内容
删除~/Library/Preferences/com.torusknot.SourceTreeNotMAS.plist（您应该使用SourceTree的直接版本，因此“NotMAS”）office转图片或pdf（简易方案）
安装环境shell脚本（centos7）
#!/bin/bash
#suppor china
yum install wqy-microhei-fonts wqy-zenhei-fonts
#office to pdf
yum install unoconv -y
#pdf to slide image
yum install ImageMagick -y使用node构造核心类officeCovert.js
const unoconv = require('awesome-unoconv');
const fs = require('fs');
const child_process = require("child_process");
class OfficeCovert{
//file to pdf
file2pdf(sourceFile, generateFile){
return unoconv.convert(sourceFile, generateFile);
}
//file to image list
file2images(file, path, prefix = '', suffix ='', ext = 'png'){
return new Promise((resolve, reject)=> {
if(fs.existsSync(file)){
this.rm(path);
this.mkdir(path);
child_process.exec(`convert ${file} ${path}/${prefix}%d${suffix}.${ext} `, (...args) =>{
if(args && args[0] === null){
resolve(path);
}else{
reject(...args);
}
}, err => {
reject(err);
});
}else{
reject('file not found');
}
});
}
//delete file or path
rm(path){
let files = [];
if(fs.existsSync(path)){
if(fs.statSync(path).isDirectory()){
files = fs.readdirSync(path);
files.forEach((file, index)=> {
let curPath = path + '/' + file;
if(fs.statSync(curPath).isDirectory()){
this.rm(curPath);
}else{
fs.unlinkSync(curPath);
}
});
}else{
fs.unlinkSync(path);
}
}
}
//create path
mkdir(path){
if(!fs.existsSync(path)){
fs.mkdir(path,{ recursive: true }, res=> {
if(res){
console.warn(res);
}
});
}
}
}
module.exports = OfficeCovert;入口文件index.js
const {resolve} = require('path');
const OfficeCovert = require('./officeCovert');
//定义需要转换的文件
const pptFile = resolve('./office/test2.pptx');
//生成pdf名称
const pdfFile = resolve('./output/test2.ppf');
//设置图片目录
const imgFile = resolve('./output/test2/tst');
const oc = new OfficeCovert();
//geneate pdf
oc.file2pdf(pptFile, pdfFile).then(gFile =>{
//generate image
oc.file2images(gFile, imgFile, 'test11', 'mytest', 'png').then(path=> {
console.log('generate image success !!!!', path);
//clean file
oc.rm(gFile);
}).catch((...args) => {
console.log(args);
});
});函数式编程
