1、关闭所有防火墙

Linux CentOS-7 关闭2个防火墙_懒笑翻的博客-CSDN博客1、system--------查看防火墙状态systemctl status firewalld--------关闭防火墙systemctl stop firewalld2、service------查看防火墙状态service firewalld status--------关闭防火墙service firewalld stop[bigdata@localhost ~]$ systemctl status firewalld● firew.https://blog.csdn.net/c_lanxiaofang/article/details/124675626?csdn_share_tail=%7B%22type%22%3A%22blog%22%2C%22rType%22%3A%22article%22%2C%22rId%22%3A%22124675626%22%2C%22source%22%3A%22c_lanxiaofang%22%7D&ctrtid=EclCp

2、进入到hadoop 的 sbin 目录下，启动stop-all.sh 关闭所有进程，并通过 jps 查看进程

[bigdata@localhost ~]$ cd /home/bigdata/Opt/hadoop-2.10.1/sbin
[bigdata@localhost sbin]$ ./stop-all.sh
This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh
Stopping namenodes on [192.168.232.139]

[bigdata@localhost sbin]$ jps

3、切换到root权限的用户，通过 start-all.sh 启动所有hadoop进程，通过 jps 查看进程

[bigdata@localhost sbin]$ su root
Password: 
[root@localhost sbin]# ./start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [192.168.232.139]

4、使用root用户，下载 ntp 对服务器进行时间同步

# 安装ntp服务

yum install ntp

# 设置服务启动方式

systemctl enable ntpd

# 启动服务

service ntpd restart

# 将系统时区修改为上海时间

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

# 启动HBase

start-hbase.sh

#查看

jps

[bigdata@localhost ~]$ su root
Password: 
[root@localhost bigdata]# yum install ntp
