192.168.1.32 server2 server2.smartmap.com

192.168.1.33 server3 server3.smartmap.com

2.2.2. 设置/etc/sysconfig/network文件

该文件是：Name Service Caching Daemon (NSCD)

[root@master ~]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=master.smartmap.com

2.3. 修改ulimit（最大进程数和最大文件打开数)

[ambari@master ~]$ sudo vi /etc/security/limits.conf

* soft nofile 204800

* hard nofile 204800

* soft nproc 204800

* hard nproc 204800

[ambari@master ~]$ sudo vi /etc/security/limits.d/20-nproc.conf

# * soft nproc 4096

* soft nproc 204800

* hard nproc 204800

root soft nproc unlimited

[root@master ~]# yum install unzip wget ntp

[root@master ~]# systemctl is-enabled ntpd

disabled

[root@master ~]# systemctl enable ntpd

Created symlink from /etc/systemd/system/multi-u ser.target.wants/ntpd.service to /usr/lib/system d/system/ntpd.service.

[root@master ~]# systemctl start ntpd

[root@master ~]#

2.6. 添加用户

[root@master ~]# useradd ambari

[root@master ~]# passwd ambari

Changing password for user ambari.

New password:

BAD PASSWORD: The password is shorter than 8 characters

Retype new password:

passwd: all authentication tokens updated successfully.

[root@master ~]# chmod u+w /etc/sudoers

[root@master ~]#

[root@master ~]# vi /etc/sudoers

添加如下内容：

ambari ALL=(ALL) NOPASSWD: ALL

2.7. 配置SSH免密码登录
