1. mysql备份
A patch adding name=all was added to the mysql_db module on May 12, 2015, so the recommended way to dump all databases is:
# Dumps all databases to hostname.sql
- mysql_db: state=dump name=all target=/tmp/{{ inventory_hostname }}.sql
每个数据库一个文件：
---
# This playbook backups all mysql databases into separate files.
- name: backup mysql
vars:
- exclude_db:
- "Database"
- "information_schema"
- "performance_schema"
- "mysql"
tasks:
- name: get db names
shell: 'mysql -u root -p{{ vault_root_passwd }} -e "show databases;" '
register: dblist
- name: backup databases
mysql_db:
state: dump
name: "{{ item }}"
target: "/tmp/{{ item }}.sql"
login_user: root
login_password: "{{ vault_root_passwd }}"
with_items: "{{ dblist.stdout_lines | difference(exclude_db) }}"
