1. 发布流程：
- 代码发布：
- git
- saltstack: state推送文件
- saltstack: state执行命令
- 静态文件发布
- git
- saltstack: state推送文件
- SQL发布
- git
- saltstack: state推送文件
- saltstack: state执行命令
注意：
1. 保留三个版本
2. SQL发布：数据量比较大时，编写上线SQL时，只对更改的表做操作；+ 回滚的脚本；
2. 发布salt相关命令：
代码:
目录：/srv/salt/code_deply/
a. 创建 init.sls
# 1. 同步文件
sync_file:
file.recurse:
- name: /data/new_files/{{pillar['file_name']}} # 同步到所有minion
- source: salt://s7code/files/{{pillar['file_name']}} # 新拉下来的代码
- user: root
- makedirs: True
- file_mode: 644
- dir_mode: 755
sync_reboot_file:
file.manage:
- name: /data/backup/reboot_{{pillar['file_name']}}.py # 同步到所有minion
- source: salt://s7code/files/reboot_{{pillar['file_name']}}.py # 新拉下来的代码
- user: root
- makedirs: True
- file_mode: 644
sync_backup_file:
file.manage:
- name: /data/backup/backup_{{pillar['file_name']}}.py # 同步到所有minion
- source: salt://s7code/files/backup_{{pillar['file_name']}}.py # 新拉下来的代码
- user: root
- makedirs: True
- file_mode: 644
# 2. 备份
backup_online:
cmd.run:
- name: mv /data/{{pillar['file_name']}} /data/backup/{{pillar['file_name']}}-4
- require:
- file: sync_file
# 3. 新上线代码
apply_file:
cmd.run:
- name: mv /data/new_files/{{pillar['file_name']}} /data/{{pillar['file_name']}}
- require:
- cmd: backup_online
# 4. 重启程序
reboot_app:
file.run:
- name: /usr/bin/python /xx/xx/xxpython脚本.py {{pillar['file_name']}} (将现在运行的进程杀掉，重启)
# 5. 备份名称重命名
rename_backup_file:
cmd.run:
- name: /usr/bin/python /data/backup/backup_rename.py {{pillar['file_name']}}（找到/data/backup目录下的所有文件夹，）
