python3⾃动运维_Python3⾃动化运维
前⾔本⽂选⽤的Python服务器操作系统，是最常⽤于开发和⽣产环境的Linux系统：Ubuntu和Centos。
为了测试⽅便和快速部署，本⽂将使⽤Docker + Rancher来部署环境。 Docker和Rancher的使⽤可参看本博的其他⽂章。本⽂只记录实际操作过程中的必要步骤，并⾮完全步骤。

# 在rancher下新建并启动容器(以下都为在rancher⾥操作 SSH端⼝16022)
# docker镜像中不启动SSH，也没有设定时区，需要在rancher⾥设置以下两项se是常量元素还是微量元素
命令：/usr/sbin/sshd -D
添加卷：/etc/localtime:/etc/localtime:ro
# 其他命令参考

Windows客户端配置
相关软件Sublime3
Atom: atom.io/ (本课程使⽤版本1.28.0)
⽤Sublime搭建Python开发环境
python安装时指定路径如D:PythonPython36，若安装后没有⾃动添加环境变更，⼿动将以下内容添加到PATH中D:PythonPython36;D:PythonPython36Scripts;
print('hello world')
# 保存成1.py ctrl + b 运⾏，能成功显⽰表⽰配置成功
Atom安装使⽤
windows下安装使⽤默认设置(下⼀步下⼀步)，若安装后没有⾃动添加环境变更，⼿动将以下内容添加到PATH中
C:UsersliuyajunAppDataLocalatombin
更换atom apm 国内源(加快package安装速度)，修改C:Usersliuyajun.atom.apm.apmrc⽂件，添加以下内容：
registry=registry./
strict-ssl=false
安装后检测是否成功，windows cmd中执⾏apm install --check
Checking for native build tools done # done 代表检测正常
打开ATMO安装常⽤包，setting -> Install -> 搜索chineses和ftp，选择以下两个包安装
simplified-chinese-menu Atom 的简体中⽂语⾔包，完整，兼容所有已发布版本 Atom
remote-ftp Enable browsing remote FTP/FTPS/SFTP just like the built-in Tree View. Requires a proje
ct.
重启atom，atom如果报错"Cannot load the system dictionary for zh-CN"，解决⽅法是打开Atom-Files-Settings-Packages搜索spell check，发现了这个spell-check的插件，
取消掉Use Locales前⾯的勾选或者⼿动填写en-US设置⽂件名称。
atom常⽤快捷键ctrl-alt-c remote-ftp:connect Remote Ftp atom-workspace
ctrl-alt-d remote-ftp:disconnect Remote Ftp atom-workspace
ctrl-alt-o remote-ftp:toggle Remote Ftp atom-workspace
新建Atom项⽬
WINDOWS在⼯作⽬录下新建⼀个空⽬录，如centos-16022，将这个⽬录拖拽到Atom中，然后扩展->Remote FTP->Create SFTP config file
修改 host/port/user/pass⼏项内容后保存{
"protocol": "sftp",
"host": "10.240.4.160",
"port": 16022,
"user": "root",
"pass": "ydgw",
"promptForPass": false,
"remote": "/",
"local": "",
"agent": "",
"privatekey": "",
"passphrase": "",
"hosthash": "",
"ignorehost": true,
