mkdir -p tools
cd tools

下載JDK，後邊的下載地址你可以到 orcal 官網去獲取最新的版本，或者你想要的版本進行替換。

# jdk 8 已經包含 jre

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u181-b13/96a7b8442fe848ef90c96a2fad6ed6d1/jdk-8u181-linux-x64.rpm"

# jdk 10
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/10.0.2+13/19aef61b38124481863b1413dce1855f/jdk-10.0.2_linux-x64_bin.rpm"

# jre10

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/10.0.2+13/19aef61b38124481863b1413dce1855f/jre-10.0.2_linux-x64_bin.rpm"
 

安裝

sudo yum localinstall jdk-****-linux-x64.rpm

Now Java should be installed at /usr/java, and linked from /usr/bin/java.

設置環境變量

將下邊的代碼添加到 profile 文件末尾

vim /etc/profile

# 註意jdk安裝路徑保持一致
export JAVA_HOME=/usr/java/default/
export JRE_HOME=/usr/java/default/jre
PATH=$PATH:$JRE_HOME/bin:$JAVA_HOME/bin

啟用新的配置

source /etc/profile
