1、下载安装包。mongodb-linux-x86_64-rhel62-3.6.3.tgz
2、解压。修改名字。
3、修改配置文件：
# mongodb.conf
#where to log
logpath=/eyuroot/mongodb/log/mongodb.log
# fork and run in background
fork = true
#port = 27017
dbpath=/eyuroot/mongodb/data
pidfilepath=/eyuroot/mongodb/mongodb.pid
4、启动脚本：
#!/bin/sh
#
# mongodb init file for starting up the MongoDB server
#
# chkconfig: - 20 80
# description: Starts and stops the MongDB daemon that handles all
# database requests.
# Source function library.
. /etc/rc.d/init.d/functions
exec="/usr/bin/mongod"
prog="mongod"
logfile="/eyuroot/mongodb/log/mongodb.log"
options=" -f /etc/mongod.conf"
[ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$prog
lockfile="/var/lock/subsys/mongod"
start() {
[ -x $exec ] || exit 5
echo -n $"Starting $prog: "
#daemon --user mongod "$exec --quiet $options run >> $logfile 2>&1 &"
daemon --user mongod "$exec --quiet $options run > /dev/null"
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
stop
start
}
reload() {
restart
}
force_reload() {
restart
}
rh_status() {
# run checks to determine if the service is running or use generic status
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0
$1
;;
stop)
rh_status_q || exit 0
$1
;;
restart)
$1
;;
reload)
rh_status_q || exit 7
$1
;;
force-reload)
force_reload
;;

rh_status

condrestart|try-restart)
rh_status_q || exit 0
restart
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
exit 2
esac
exit $?
5、如果有报错，请检查目录权限。
6、加入到开机启动中：
chkconfig --add mongod
chkconfig mongod on
