一、系統准備
1. 創建user——ambari
2.關閉防火牆
redhat6：
chkconfig iptables off
/etc/init.d/iptables stop
redhat7：
systemctl disable firewalld
service firewalld stop
3.檢查最大打開文件數，如果小於10000，需要修改
ulimit -Sn
ulimit -Hn
If the output is not greater than 10000, run the following command to set it to a suitable default:
ulimit -n 10000
4.關閉selinux
學習到一個重啟后失效的關閉selinux命令，記錄一下
setenforce 0
5.開啟ntpd服務（確保集群內部時鍾統一）
chkconfig --list ntpd
chkconfig ntpd on
6.關閉packagekit（作用：可以同時啟多個yum）
vi /etc/yum/pluginconf.d/refresh-packagekit.conf
enabled=0
7.設置umask（設定用戶所創建目錄的初始權限）
Setting the umask for your current login session:
umask 0022
Checking your current umask:
umask 0022
Permanently changing the umask for all interactive users:
echo umask 0022 >> /etc/profile
8.安裝jdk
9.安裝openssl1.0.1
wget http://www.openssl.org/source/openssl-1.0.1t.tar.gz
tar xzvf openssl-1.0.1t.tar.gz
./config
make
make install
cd /usr/local/ssl/
./bin/openssl version -a
替換舊版openssl
mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/include/openssl /usr/include/openssl.old(沒用到)
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/ssl/include/openssl/ /usr/include/openssl(沒用到)
配置庫文件搜索路徑
echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
ldconfig
10.配置ssh互信
二、離線安裝
1.下載（分發）
