NBU7.5版本目前官方兼容列表提示Redhat7最低是7.6.1.1
不过经过测试其实是一样可以安装的
一、下载NBU7.5客户端
客户端可以从官网上面下载下载7.7以后的版本

7.5的客户端地址

二、安装xinetd(这个很关键，没有安装的话NBU会报错安装会有问题)
可以讲Redhat7的光盘里面找得到Package有xinetd安装并启动
rpm -ivh xinetd-2.3.15-13.el7.x86_64.rpm
重点来了（添加一个启动脚本因为redhat7是用systemctrl启动，但是7.5安装的时候回去读取这个文件所以手动创建一下）
vim /etc/init.d/xinetd
#!/bin/bash
#
# xinetd This starts and stops xinetd.
#
# chkconfig: 345 56 50
# description: xinetd is a powerful replacement for inetd. /
# xinetd has access control machanisms, extensive /
# logging capabilities, the ability to make services /
# available based on time, and can place /
# limits on the number of servers that can be started, /
# among other things.
#
# processname: /usr/sbin/xinetd
# config: /etc/sysconfig/network
# config: /etc/xinetd.conf
# pidfile: /var/run/xinetd.pid
prog="xinetd"
PATH=/sbin:/bin:/usr/bin:/usr/sbin
# Source function library.
. /etc/rc.d/init.d/functions
# Get config.
test -f /etc/sysconfig/network && . /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "yes" ] || exit 0
[ -f /usr/sbin/xinetd ] || exit 1
[ -f /etc/xinetd.conf ] || exit 1
RETVAL=0
start(){
echo -n $"Starting $prog: "
# Need to get rid of localization for external services -
# it doesn make much sense to have i18n on the server side here
LANG=en_US
LC_TIME=en_US
LC_ALL=en_US
LC_MESSAGES=en_US
LC_NUMERIC=en_US
LC_MonETARY=en_US
LC_COLLATE=en_US
export LANG LC_TIME LC_ALL LC_MESSAGES LC_NUMERIC LC_MonETARY LC_COLLATE
unset HOME MAIL USER USERNAME
daemon xinetd -stayalive -reuse -pidfile /var/run/xinetd.pid
RETVAL=$?
echo
touch /var/lock/subsys/xinetd
return $RETVAL
}
stop(){
echo -n $"Stopping $prog: "
killproc xinetd
RETVAL=$?
echo
rm -f /var/lock/subsys/xinetd
return $RETVAL
}
reload(){
echo -n $"Reloading configuration: "
killproc xinetd -USR2
RETVAL=$?
echo
return $RETVAL
}
restart(){
stop
start
}
condrestart(){
[ -e /var/lock/subsys/xinetd ] && restart
return 0
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status xinetd
;;
restart)
restart
;;
reload)
reload
;;
condrestart)
condrestart
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|reload}"
RETVAL=1
esac
exit $RETVAL
然后加可执行权限，启动xinetd并设置开机启动（启动如果报错有可能是字符编码的问题，vim进入xinetd文件:set ff=unix 然后:wq即可）
chmod +x /etc/init.d/xinetd /etc/init.d/xinetd start systemctrl enable xinetd
三、安装NBU7.5到Redhat7
首先检测xinetd是否启动
ps -ef|grep xinetd
解压NBU客户端
进入目录开始安装
后面界面就下一步下一步即可添加授权的时候输入授权然后就n不继续添加
