基於ansible的zabbix源代碼安裝

1、ansible簡介

ansible是新出現的自動化運維工具，基於Python開發，集合了眾多運維工具（puppet、cfengine、chef、func、fabric）的優點，實現了批量系統配置、批量程序部署、批量運行命令等功能。ansible是基於模塊工作的，本身沒有批量部署的能力。真正具有批量部署的是ansible所運行的模塊，ansible只是提供一種框架。我們現在通過ansible來實現zabbix的批量安裝。

zabbix我就不多說了，現在是一門比較熱的監控軟件。

[root@node1 ~]# clear
[root@node1 ~]# cd /usr/local/src/
先安裝lrzsz的軟件包，然後上傳zabbix-3.2.7.tar.gz，zabbix壓縮包可在官網下載
[root@node1 src]# rz 
[root@node1 src]# ls
apr-1.6.2          apr-util-1.6.0.tar.gz  httpd-2.4.27.tar.gz  shuzu.sh         while_ping.sh
apr-1.6.2.tar.bz2  a.sh                   nginx-1.12.0         test_hangshu.sh  zabbix-3.2.7.tar.gz
apr-util-1.6.0     httpd-2.4.27           nginx-1.12.0.tar.gz  while_login.sh
[root@node1 src]#

接下來我們是基於ansible自動化源碼安裝zabbix，所以我們先安裝ansible

[root@node1 src]# yum install -y ansible

ansible的應用需要使用ssh-keygen生成私鑰和公鑰

生成公鑰

[root@node1 src]# ssh-keygen 
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
c6:4d:7a:b3:dc:96:12:81:a2:44:44:29:24:2f:3a:de root@node1
The key‘s randomart image is:
+--[ RSA 2048]----+
|...o+.           |
| o...    .       |
|. ... . . o      |
|.. . . o + .     |
|o   .   S =      |
|...    . o = .   |
| . E      + +    |
|           o     |
|                 |
+-----------------+

生成客戶端的密鑰

[root@node1 src]# ssh-copy-id 172.25.0.32
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
[email protected]‘s password: 
Number of key(s) added: 1
Now try logging into the machine, with:   "ssh ‘172.25.0.32‘"
and check to make sure that only the key(s) you wanted were added.

修改ansible的hosts文件，針對指定客戶端進行推送

進入hosts文件找到[webservers]把註釋去掉,再添加客戶端的ip

[root@node1 src]# cat /etc/ansible/hosts
[webservers]
##alpha.example.org
##beta.example.org
## 192.168.1.100
## 192.168.1.110
172.25.0.32

接下來我們開始配置ansible基於jinjia的模板，寫個zabbix的基於ansible源代碼安裝文件

ansible的變量支持類型主要是以下幾個

字符串：使用單引號或雙引號；

數字：整數、浮點數；

列表：[item1, item2, ...]

元組：(item1, item2, ...)

字典：{key1:value1, key2:value2, ...}

布爾型：true/false

服務端安裝：

編寫ansible文件

[root@node2 ~]# cat /etc/ansible/install_zabbix.yaml 
- hosts: webservers
  remote_user: root
  tasks: 
  - name: install packages
    yum: name={{ item }} state=latest
    with_items:                  ###搭建lamp環境，安裝環境依賴的包
    - make                              
    - mysql-server

  - name: copy install_shell to clien
    copy: src=install_zabbix.sh dest=/tmp/install_zabbix.sh
    notify: install shell
  handlers:
  - name: install shell
    shell: /bin/bash /tmp/install_zabbix.sh

zabbix源代碼安裝腳本

[root@node1 php]# cat /usr/local/src/install_zabbix.sh
#!/bin/bash
useradd zabbix -s /sbin/nologin
expect -c "
spawn /usr/bin/mysql_secure_installation

###寫完了腳本別忘

檢測ansible文件，沒問題

[root@node1 php]# ansible-playbook -C  /etc/ansible/install_zabbix.yaml 
PLAY [webservers] **************************************************************************************
TASK [Gathering Facts] *********************************************************************************
ok: [172.25.0.32]
TASK [install packages] ********************************************************************************
ok: [172.25.0.32] => (item=[u‘make‘, u‘mysql-server‘, u‘httpd‘, u‘php‘, u‘mysql-devel‘, u‘gcc‘, u‘net-snmp-devel‘, u‘curl-devel‘, u‘perl-DBI‘, u‘php-gd‘, u‘php-mysql‘, u‘php-bcmath‘, u‘php-mbstring‘, u‘php-xml‘, u‘unixODBC-devel‘, u‘OpenIPMI-devel‘, u‘libxml2-devel‘])
TASK [copy zabbix to clien] ****************************************************************************
changed: [172.25.0.32]
TASK [copy install_shell to clien] *********************************************************************
changed: [172.25.0.32]
RUNNING HANDLER [install shell] ************************************************************************
skipping: [172.25.0.32]
PLAY RECAP *********************************************************************************************
172.25.0.32                : ok=4    changed=2    unreachable=0    failed=0

再執行一遍就可以安裝了

[root@node1 php]#ansible-playbook  /etc/ansible/install_zabbix.yaml

2、zabbix客戶端安裝:

ansibleZ在zabbix的應用的比較重要的部分是推送客戶端

編寫ansible文件

[root@node2 ~]# cat /etc/ansible/install_zabbix.yaml 
- hosts: webservers     ##如果你是大批量安裝，把webservers 改成all,不過先添加密鑰ssh-keygen+key-copy-id + 客戶端ip
  remote_user: root
  tasks: 
  - name: copy zabbix.tar to clien
    copy: src=/usr/local/src/zabbix-3.2.7.tar.gz  dest=/usr/local/src/
  - name: copy install_shell to clien
    copy: src=install_zabbix_client.sh dest=/tmp/install_zabbix_client.sh
    notify: install shell
  handlers:
  - name: install shell
    shell: /bin/bash /tmp/install_zabbix_client.sh

推送給客戶端的腳本文件：

[root@node1 ansible]# cat  install_zabbix_client.sh
#!/bin/bash
useradd zabbix -s /sbin/nologin
cd /usr/local/src
tar zxvf  zabbix-3.2.7.tar.gz
cd /usr/local/src/zabbix-3.2.7
./configure --with-net-snmp --with-libcurl --enable-agent --prefix=/usr/local/zabbix
make && make install
cp misc/init.d/fedora/core5/zabbix_agentd /etc/init.d/
sed  -i  ‘s/ZABBIX_BIN="/usr/local/sbin/zabbix_agentd"/ZABBIX_BIN="/usr/local/zabbix/sbin/zabbix_agentd"/g‘ /etc/init.d/zabbix_agentd
sed -i ‘s/Server=127.0.0.1/Server=172.25.0.29/g‘ /usr/local/zabbix/etc/zabbix_agentd.conf  ##這個ip我寫死了172.25.0.29；是你的服務端ip，也可以寫成變量
chmod 700 /etc/init.d/zabbix_agentd
sed  -i  ‘s/# UnsafeUserParameters=0/UnsafeUserParameters=1/g‘ /usr/local/zabbix/etc/zabbix_agentd.conf

在應用腳本文件時記得要改腳本的權限，不然就無法執行。

[root@node1 ansible]# chmod a+x install_zabbix_client.sh
[root@node1 php]#  ansible-playbook -C  /etc/ansible/install_zabbix_client.yaml 
PLAY [webservers] **************************************************************************************
TASK [Gathering Facts] *********************************************************************************
ok: [172.25.0.32]
TASK [copy zabbix.tar to clien] ************************************************************************
changed: [172.25.0.32]
TASK [copy install_shell to clien] *********************************************************************
changed: [172.25.0.32]
RUNNING HANDLER [install shell] ************************************************************************
skipping: [172.25.0.32]
PLAY RECAP *********************************************************************************************
172.25.0.32                : ok=3    changed=2    unreachable=0    failed=0

測試沒問題後，以後這樣就可以實現批量對zabbix客戶端安裝了
