生产环境实战spark （5）分布式集群 5台设备之间 ssh免密码登录

之前已经在master节点单台设备上配置ssh免密码的登录工作，现在要做的事情是在5台设备之间实现ssh免密码操作。我在整个大数据集群的安装中没有使用一些hadoop的第三方的安装包工具，这里使用笨办法，SSH配置也比较简单，就一台一台的手工安装部署：

1.关闭防火墙（单台设备检查）

2.hosts文件配置（集群节点按脚本分发）

3.ssh配置（单台设备配置）

4.ssh密钥分发（集群节点按脚本分发）

分布式集群 5台设备之间 ssh免密码登录部署步骤：

1.关闭防火墙（单台设备检查）依次检查4台worker

[root@worker01 ~]# service iptables status
Redirecting to /bin/systemctl status  iptables.service
iptables.service - IPv4 firewall with iptables
   Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled)
   Active: inactive (dead)

2.hosts文件配置（集群节点按脚本分发）

2.1 先配置master节点的 hosts文件：

[root@master ~]# cat /etc/hosts
10.*.*.237 master
10.*.*.238 worker01
10.*.*.239 worker02
10.*.*.240 worker03
10.*.*.241 worker04

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost4.localdomain6

2.2  master节点建立新的目录/usr/local/rhzf_setup_scripts：

[root@master ~]# cd /usr/local
[root@master local]# ls
bin  etc  games  include  jdk1.8.0_121  lib  lib64  libexec  rhzf_spark_setupTools  sbin  share  src
[root@master local]# mkdir rhzf_setup_scripts
[root@master local]# ls
bin  etc  games  include  jdk1.8.0_121  lib  lib64  libexec  rhzf_setup_scripts  rhzf_spark_setupTools  sbin  share  src
[root@master local]# cd  rhzf_setup_scripts
[root@master rhzf_setup_scripts]# pwd
/usr/local/rhzf_setup_scripts

2.3  master节点建立复制hosts文件的分发脚本rhzf_hosts_scp.sh：

[root@master rhzf_setup_scripts]# vi rhzf_hosts_scp.sh


#!/bin/sh
for i in  238 239 240 241
do
scp   -rq /etc/hosts  root@10.*.*.$i:/etc/hosts
done

2.4  赋予执行权限，执行脚本rhzf_hosts_scp.sh：这里还没实现ssh免密码登录，因此每次登录都要输入密码

[root@master rhzf_setup_scripts]# ls
rhzf_hosts_scp.sh
[root@master rhzf_setup_scripts]# cat rhzf_hosts_scp.sh
#!/bin/sh
for i in  238 239 240 241
do
scp   -rq /etc/hosts  root@10.*.*.$i:/etc/hosts
done
[root@master rhzf_setup_scripts]# chmod u+x rhzf_hosts_scp.sh
[root@master rhzf_setup_scripts]# ls
rhzf_hosts_scp.sh
[root@master rhzf_setup_scripts]# ./rhzf_hosts_scp.sh

2.4  在worker节点上检查，hosts已经复制过去了

[root@worker04 ~]# cat /etc/hosts

[root@worker04 ~]# cat /etc/hosts

3.3 ， 在master节点上汇总密钥，再分发给客户机，编写脚本来实现，这里ssh还需要输入几次密码

[root@master rhzf_setup_scripts]# chmod u+x rhzf_ssh.sh
[root@master rhzf_setup_scripts]# cat rhzf_ssh.sh
#!/bin/sh
for i in  238 239 240 241
do
scp   -rq /root/.ssh/authorized_keys  root@10.*.*.$i:/root/.ssh/authorized_keys
done


[root@master rhzf_setup_scripts]# ./rhzf_ssh.sh

root@10.*.*.240's password:

3.4，在worker节点上检查一下密钥

[root@worker01 .ssh]# ls

3.5，在master ssh 其他worker节点，仍需密码。

[root@master rhzf_setup_scripts]# ssh worker01

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.


# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.


# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
