竟然没有 Oracle 的 JDK。 进入Oracle JDK 7，寻找最新的JDK地址，在以下代码中url替换最新的jdk地址。：
# 需要后缀参数：AuthParam
[guoning@guoning ~]$ wget http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.rpm?AuthParam=1469274764_7d8c2b160beccaecc9bdad622dac35cd
# 安装到本地
[guoning@guoning ~]$ sudo yum install jdk-7u79-linux-x64.rpm
# 检查 JDK 安装效果：
[guoning@guoning ~]$ java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
MySQL
安装 MySQL
添加 Yum 仓库:
--------------- On RHEL/CentOS 6 ---------------
wget http://dev.mysql.com/get/mysql57-community-release-el6-7.noarch.rpm
# 如果是其他版本的CentOS，可以去MySQL官网找对应的仓库url
yum localinstall mysql57-community-release-el6-7.noarch.rpm
检查仓库是否添加成功
yum repolist enabled | grep "mysql.*-community.*"
安装 MySQL 的命令：
yum install mysql-community-server
# 上面的命令默认会安装最新版的MySQL，其他版本的MySQL，可配置 MySQL Yum仓库的子仓库：
# yum-config-manager --disable mysql57-community
# yum-config-manager --enable mysql56-community
启动，设置密码
修改 my.cnf 文件：
...
[mysqld]
# 新增配置：
skip-grant-tables
...
重启 MySQL ：
service mysqld restart
连接 MySQL，修改密码：
mysql> update mysql.user set authentication_string=PASSWORD('rootROOT') where User='root';
mysql> flush privileges;
修改 my.cnf 文件中，MySQL 的启动配置：
[mysqld]
# 去除配置：
# skip-grant-tables
# 新增配置：
validate_password=OFF
重启 MySQL ：
service mysqld restart
重新连接 MySQL：
[root@guoning ~]# mysql -uroot -p
Enter password:
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> SET PASSWORD = PASSWORD('****');
Maven
思考：设置 repo 后，通过 yum 命令来安装所需的软件。
Maven 官网，下载 maven 安装包：
# 下载安装包
$ wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
# 解压
$ tar -zxvf apache-maven-3.3.9-bin.tar.gz
# 移动到指定位置，集中存放
$ mv apache-maven-3.3.9 /usr
/etc/profile 文件中，修改环境变量：
# 文件末尾
# 用户安装的软件
MAVEN_HOME=/usr/apache-maven-3.3.9
export PATH=${MAVEN_HOME}/bin:${PATH}
