如何理解ansible自動(dòng)化運(yùn)維數(shù)據(jù)庫(kù)

這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)?lái)有關(guān)如何理解ansible自動(dòng)化運(yùn)維數(shù)據(jù)庫(kù)，文章內(nèi)容豐富且以專業(yè)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(guò)ansible簡(jiǎn)單對(duì)數(shù)據(jù)庫(kù)主機(jī)檢查和數(shù)據(jù)庫(kù)表空間的檢查，前提數(shù)據(jù)庫(kù)主機(jī)有統(tǒng)一的用戶名和密碼.

 運(yùn)維環(huán)境： rhel 7.2， ansible 1.9
 數(shù)據(jù)庫(kù)環(huán)境：Oracle 11.2.0.4, Suse 11sp4,統(tǒng)一用戶是Oracle和usercs
ansible配置文件/etc/ansible/ansible.cfg,否則在運(yùn)行ansible時(shí)需要制定host位置
--配置host組
[root@DBAMONITOR usercs]# more /ansible/hosts

192.168.15.21
192.168.15.22
192.168.15.46
192.168.15.47


--簡(jiǎn)單測(cè)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 "ls -l /tmp" -u usercs -k

--復(fù)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(yuǎn)程執(zhí)行腳本
