nagios自动安装脚本（一个脚本实现服务端+客户端自动安装）

#!/bin/bash
# filename: nagios-install.sh
###################脚本运行的环境###############################
########1、服务端和客户端能正常通信;
########2、所需软件包：（nagios-3.2.0.tar.gz      nagios-plugins-1.4.14.tar.gz  pnp-0.4.13.tar.gz
########  nagios-cn-3.2.0.tar.bz2  nrpe-2.12.tar.gz）；
########3、这些软件包需放在服务端的root用户的家目录下,root的密码是'666666'
###################(前期准备工作)###############################
## (3、定义服务端和客户端的IP变量)############################
read -p "请输入服务端的IP地址：" SIP
read -p "请输入客户端的IP地址：" CIP
##（2、定义非交互式登录客户机的函数）#########################
auto_login_ssh () {
expect -c "set timeout -1;
spawn -noecho ssh -o StrictHostKeyChecking=no $2 ${@:3};
expect *assword:*;
send -- $1\r;
interact;";
}
##（3、定义非交互式scp的函数）################################
auto_scp () {
expect -c "set timeout -1;
spawn scp -o StrictHostKeyChecking=no ${@:2};
expect {
*assword:* {send -- $1\r;
expect {
*denied* {exit 1;}
eof
}
}
eof         {exit 1;}
}
"
return $?
}
##（4、复制tar包到客户端）##############################################
auto_scp 666666 ~/nagios-plugins-1.4.14.tar.gz root@$CIP:~/ &>/dev/null && echo "非交互式完成nagios-plugins-1.4.14.tar.gz的scp复制。"
auto_scp 666666 ~/nrpe-2.12.tar.gz root@$CIP:~/ &>/dev/null && echo "非交互式完成nrpe-2.12.tar.gz的scp复制。"
##（4、让此脚本中需要在客户端执行的行，保存到新的脚本client.sh.并把client.sh复制到客户端并执行。）
sed '/^#/! s/^/#/; 47,80 s/#//' ~/nagios-install.sh >~/client.sh
sed -i "/^#/! s/\$SIP/$SIP/" ~/client.sh
auto_scp 666666 ~/client.sh root@$CIP:~/ &>/dev/null && echo "非交互式完成client.sh的scp复制。"
echo "远程到客户端，正在客户端执行脚本client.sh,无需任何操作。请稍作等待"
auto_login_ssh 666666 root@$CIP /bin/bash client.sh
echo "客户端上执行脚本client.sh完成。"
##################(需在客户端执行的47-80行脚本)######################
##（1、用yum安装mysql,vsftp）
#[ -e /mnt/Server ] || mount /dev/cdrom /mnt
#cat > /etc/yum.repos.d/aa.repo <<EOF
#[base]
#name=dvd server
#baseurl=file:///mnt/Server
#gpgcheck=0
#EOF
#yum -y install mysql* vsftpd* &>/dev/null && echo "install mysql* vsftpd* install is ok"
#service mysqld start &>/dev/null && echo "mysqld start is ok."
#service vsftpd start &>/dev/null && echo "vsftpd start is ok."
##(2、安装nagios-plugins、nrpe)
#cd ~
#useradd -s /sbin/nologin nagios
#tar zxf nagios-plugins-1.4.14.tar.gz &>/dev/null
#cd nagios-plugins-1.4.14
#./configure &>/dev/null && echo "nagios-plug_cfg is ok."
#make &>/dev/null && echo "nagios-plug make is ok."
#make install &>/dev/null && echo "nagios-plug make install is ok."
#chown nagios:nagios /usr/local/nagios/
#chown -R nagios.nagios /usr/local/nagios/libexec/
#cd ~
#tar xf nrpe-2.12.tar.gz
#cd nrpe-2.12
#./configure &>/dev/null;
#make all &>/dev/null;
#make install-plugin &>/dev/null;
#make install-daemon &>/dev/null;
#make install-daemon-config &>/dev/null && echo "nrpe install is ok"
#sed -i "79 s/$/,$SIP/" /usr/local/nagios/etc/nrpe.cfg
#sed -i '199,203 s/\]/_1\]/' /usr/local/nagios/etc/nrpe.cfg
#/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
#/usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 &>/dev/null
#[ $? -eq 0 ] && echo "nrpe 已经正常工作。"
