export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

# 使配置文件即时生效
source /etc/profile

# 检查jdk是否安装按成
java -version

二.MySQL

# mysql
rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

# 常用操作命令
systemctl enable mysqld
systemctl start mysqld
