Ansible 插件 之 CMDB安装和使用

Posted 2020-11-20

这里演示ansible-cmdb插件的安装，web展示和导入mysql数据库的示例
安装环境：
Centos7
IP：10.1.1.10

1、安装apache：
[[email protected] ~]yum install httpd
因为要使用web浏览，所以安装apache

2、安装ansible-cmdb插件

[[email protected] opt]# wget https://files.pythonhosted.org/packages/37/1b/1fcff0a38a4e07d9d3f75113494ec0b25fd271b650bda52907ae1a80cbfb/ansible-cmdb-1.27.tar.gz

[[email protected] opt]# tar -xvf ansible-cmdb-1.27.tar.gz
[[email protected] opt]# cd ansible-cmdb-1.27
[[email protected] ansible-cmdb-1.27]# python setup.py install

安装完成后，把解压目录的src(/ansible-cmdb-1.27/src)目录下的ansible-cmdb.py文件复制到/usr/bin/目录下

如果不复制ansible-cmdb.py文件复制到/usr/bin/目录，下面生成html文件或其他文件格式的时候会
报错，报错提示为：Couldn‘t find /usr/bin/ansible-cmdb.py in . or /usr/bin/../lib/ansible-cmdb/ or /usr/bin/../lib/ansiblecmdb/ (cwd=/opt/ansible-cmdb-1.27/src)

3、使用

（1）、生成所有主机得facts信息
[[email protected] ~]# mkdir?out
[[email protected] ~]# ll
drwxr-xr-x. 2 root root 40 Jun 27 20:30 out

[[email protected] ~]# ansible all -m setup --tree out/

（2）、将生成的facts信息生成web页面
[[email protected] ~]# ansible-cmdb out/ > overview.html
[[email protected] ~]# ll
drwxr-xr-x. 2 root root 40 Jun 27 20:30 out
-rw-r--r--. 1 root root 118584 Jun 27 20:43 overview.html

a、以资产列表得形式统计出ansible主机信息。

[[email protected] ~]# ansible-cmdb -t txt_table --columns name,os,ip,mem,cpus out/
Name OS IP Mem CPUs

---

10.1.1.12 CentOS 7.3.1611 192.168.43.94 0g 1
localhost CentOS 7.3.1611 192.168.43.187 0g 1
[[email protected] ~]#

b、把overview.html复制到/var/www/html/test/目录下
[[email protected] ~]# cp overview.html /var/www/html/test
可能需要改权限：
[[email protected] ~]# chown -R apache:apache /var/www/html/test/

（3）、在web页面展示：
http://10.1.1.10/test/overview.html

（4）、输出sql文件，导入数据到mysql或者SQLite

A、输出为sql格式的文件：
[[email protected] ~]# ansible-cmdb -t sql out > cmdb.sql

[[email protected] ~]# ll
-rw-r--r--. 1 root root 1749 Jun 27 21:34 cmdb.sql
drwxr-xr-x. 2 root root 40 Jun 27 20:30 out
-rw-r--r--. 1 root root 118584 Jun 27 20:43 overview.html

[[email protected] ~]#

B、将数据库导入数据
[[email protected] ~]# systemctl start mysqld

[[email protected] ~]# mysql -uroot -p ansdb < cmdb.sql //将数据库导入数据

[[email protected] ~]# mysql -uroot -p
