如何理解ansible自動化運維數據庫

這期內容當中小編將會給大家帶來有關如何理解ansible自動化運維數據庫，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。

   通過ansible簡單對數據庫主機檢查和數據庫表空間的檢查，前提數據庫主機有統一的用戶名和密碼.

 運維環境： rhel 7.2， ansible 1.9
 數據庫環境：Oracle 11.2.0.4, Suse 11sp4,統一用戶是Oracle和usercs
ansible配置文件/etc/ansible/ansible.cfg,否則在運行ansible時需要制定host位置
--配置host組
[root@DBAMONITOR usercs]# more /ansible/hosts 
[Suse]
192.168.15.21
192.168.15.22
192.168.15.46
192.168.15.47


--簡單測試
[root@DBAMONITOR .ssh]# ansible Suse -m ping -u usercs -k
SSH password: 
192.168.15.22 | success >> {
    "changed": false, 
    "ping": "pong"
}


192.168.15.46 | success >> {
    "changed": false, 
    "ping": "pong"
}


192.168.15.47 | success >> {
    "changed": false, 
    "ping": "pong"
}


192.168.15.21 | success >> {
    "changed": false, 
    "ping": "pong"
}


--查看空間
[root@DBAMONITOR .ssh]# ansible Suse -m command -a "df -hT"  -u usercs -k
password:
[root@DBAMONITOR .ssh]# ansible Suse -m command -a "ls -l /tmp" -u usercs -k
password:
--復制文件：
[root@DBAMONITOR .ssh]# ansible Suse -m copy -a "src=/etc/ansible/ansible.cfg dest=/tmp/ansible.cfg" -u usercs -k
password:
{"src=/etc/ansible/ansible.cfg dest=/tmp/ansible.cfg owner=usercs group=usercs mode=0644" }


--遠程執行腳本
ansible Suse -m shell -a "/tmp/rocketzhang_test.sh"
password:
--遠程創建目錄
ansible Suse -m command -a "mkdir /home/oracle/scripts" -u oracle -k
password:
--配置腳本
source ~/.profile
