如何理解ansible自动化运维数据库

这期内容当中小编将会给大家带来有关如何理解ansible自动化运维数据库，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

   通过ansible简单对数据库主机检查和数据库表空间的检查，前提数据库主机有统一的用户名和密码.

 运维环境： rhel 7.2， ansible 1.9
 数据库环境：Oracle 11.2.0.4, Suse 11sp4,统一用户是Oracle和usercs
ansible配置文件/etc/ansible/ansible.cfg,否则在运行ansible时需要制定host位置
–配置host组
[root@DBAMONITOR usercs]# more /ansible/hosts 
[Suse]
192.168.15.21
192.168.15.22
192.168.15.46
192.168.15.47

–简单测试
[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"
}

–查看空间
[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:
–复制文件：
[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" }

–远程执行脚本
ansible Suse -m shell -a "/tmp/rocketzhang_test.sh"
password:
–远程创建目录
ansible Suse -m command -a "mkdir /home/oracle/scripts" -u oracle -k
password:
–配置脚本
source ~/.profile
sqlplus -S "/as sysdba"<<EOF

set lin 200 pages 100
 select current_scn,protection_mode,database_role,force_logging,open_mode,switchover_status from gv/$database;

set pagesize 9999 
set linesize 132 
select
a.tablespace_name,
a.Total_mb,
f.Free_mb,
round(a.total_MB-f.free_mb,2) Used_mb,
round((f.free_MB/a.total_MB)*100) "%_Free"
from
(select tablespace_name, sum(bytes/(1024*1024)) total_MB from dba_data_files group by tablespace_name) a,
(select tablespace_name, round(sum(bytes/(1024*1024))) free_MB from dba_free_space group by tablespace_name) f
WHERE a.tablespace_name = f.tablespace_name(+)
order by "%_Free"
/
exit
EOF

–拷贝文件
ansible Suse -m copy -a "src=/ansible/check_db.sh  dest=/home/oracle/scripts" -u oracle -k
password:
–执行脚本
ansible Suse -m command -a "chmod +x /home/oracle/scripts/check_db.sh" -u oracle -k 
password:
ansible Suse -m shell -a "/home/oracle/scripts/check_db.sh" -u oracle -k
password:
