zabbix客戶端自動化部署

使用expect工具實現zabbix agent自動化部署

Expect是在Tcl基礎上建立起來的，它還提供了一些Tcl所沒有的命令。
spawn命令激活一個Unix程序來進行交互式的運行。　
send命令向進程發送字符串。
expect命令等待進程的某些字符串。　
expect支持正規表達式並能同時等待多個字符串，並對每個字符串執行不一樣的操做

 

1.         安裝expect

yum –y intall expect

 

2.          建立須要安裝zabbix agent的服務器列表文件 server.txt,格式爲ip地址 空格 密碼，能夠添加多臺。

192.168.1.1 123456

192.168.1.2 123456

192.168.1.3 123456

….

 

3.          建立交互式自動安裝的expect腳本install.exp ,能夠選擇zabbix server上執行,IP地址爲192.168.1.254，密碼爲123456

#!/usr/bin/expect -f

set ipaddress [lindex $argv 0]

set passwd [lindex $argv 1]

set timeout 30

spawn ssh root@$ipaddress

expect {

        "yes/no" { send "yes\r";exp_continue }

        "password:" { send "$passwd\r" }

}

expect "]#"

send "scp root@192.168.1.254:/usr/local/src/zabbix-1.8.2.tar.gz /usr/local/src\r"

expect {

        "yes/no" { send "yes\r";exp_continue }

    "password:" { send "123456\r" }

}

expect "]#"

send "useradd zabbix\r"

expect "]#"

send "cd /usr/local/src/\r"

expect "src]#"

send "tar zxf zabbix-1.8.2.tar.gz\r"

expect "src]#"

send "cd zabbix-1.8.2\r"

expect "zabbix-1.8.2]#"

send "./configure --prefix=/usr/local/zabbix --enable-agent >& /dev/null\r"

expect "zabbix-1.8.2]#"

send "make >& /dev/null\r"

expect "zabbix-1.8.2]#"

send "make install >& /dev/null\r"

expect "zabbix-1.8.2]#"

send "echo zabbix-agent 10055/tcp Zabbix Agent >> /etc/services\r"

send "echo zabbix-agent 10055/udp Zabbix Agent >> /etc/services\r"

send "mkdir /etc/zabbix\r"

send "cp misc/conf/zabbix_agent.conf /etc/zabbix/\r"

send "cp misc/conf/zabbix_agentd.conf /etc/zabbix/\r"

expect "zabbix-1.8.2]#"

send "sed -i \"82s#127.0.0.1#192.168.1.254#\" /etc/zabbix/zabbix_agentd.conf\r"

send "sed -i \"91s#Zabbix Server#\$HOSTNAME#\" /etc/zabbix/zabbix_agentd.conf\r"

send "sed -i \"201s/#//\" /etc/zabbix/zabbix_agentd.conf\r"

send "sed -i -e \"214s/#//\" -e \"214s/0/1/\" /etc/zabbix/zabbix_agentd.conf\r"

send "cp misc/init.d/fedora/core/zabbix_agentd /etc/init.d/\r"

expect "zabbix-1.8.2]#"

send "chmod a+x /etc/init.d/zabbix_agentd\r"

send "sed -i \"19s#/opt#/usr/local#\" /etc/init.d/zabbix_agentd\r"

send "sed -i \"25s#bin#sbin#\" /etc/init.d/zabbix_agentd\r"

send "chkconfig --add zabbix_agentd\r"

send "mkdir /etc/zabbix/zabbix_agentd\r"

expect "]#"

send "scp root@192.168.1.254:/etc/zabbix/zabbix_agentd/zabbix_agent.userparams.conf /etc/zabbix/zabbix_agentd\r"

expect {

          "yes/no" { send "yes\r";exp_continue }

          "password:" { send "123456\r" }

}  

expect "]#"

send "/etc/init.d/zabbix_agentd start\r"

expect "]#"

send "exit\r"

 

4.         建立shell腳原本聯合執行以上2個文件，zabbix.sh

#!/bin/bash

for i in `awk '{print $1}' server.txt`

do

        j=`awk -v I="$i" '{if(I==$1)print $2}' server.txt`

        expect /root/install.exp $i $j

done

 

5.         執行./zabbix.sh 有交互信息，有錯誤可調整
