SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here. Enter current password for root (enter for none):
OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation. Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success! By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment. Remove anonymous users? [Y/n] Y
... Success! Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y
... Success! By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment. Remove test database and access to it? [Y/n] n
... skipping. Reloading the privilege tables will ensure that all changes made so far
will take effect immediately. Reload privilege tables now? [Y/n] Y
... Success! All done! If you've completed all of the above steps, your MySQL
installation should now be secure. Thanks for using MySQL! Cleaning up...

1.下载安装文件
wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
2.解压安装(当前目录为/opt/build)：
tar -zxvf apache-maven-3.3.-bin.tar.gz
配置环境变量
使用vim编辑/etc/profile文件
命令：vim /etc/profile（提示：vim使用方法）
在/etc/profile文件末尾增加以下配置：
export M2_HOME=/opt/build/apache-maven-3.3.9 ##注意这里是maven的安装路径
export PATH=${M2_HOME}/bin:${PATH}
3. 重载/etc/profile这个文件
source /etc/profile
4. 检验maven是否安装成功：mvn -v
[root@VM_0_15_centos soft]# mvn -version
which: no javac in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/opt/build/apache-maven-3.3./bin)
which: no java in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/opt/build/apache-maven-3.3./bin)
Error: JAVA_HOME is not defined correctly.
We cannot execute
提示需要JDK
5.安装jdk
下载（以下url没有带oracle网站的参数，会下载失败。各位同学下载时，需要使用浏览器，点开开支链接，下载后上传，或copy正在下载的下载链接）
http://download.oracle.com/otn-pub/java/jdk/8u161-b12/2f38c3b165be4555a1fa6e98c45e0808/jdk-8u161-linux-x64.tar.gz?AuthParam=1523346641_bdbdd5a4fe9c0f61245983c83cd6a628
wget http://download.oracle.com/otn-pub/java/jdk/8u161-b12/2f38c3b165be4555a1fa6e98c45e0808/jdk-8u161-linux-x64.tar.gz
.解压安装(当前目录为/opt/jdk)：
tar -zxvf jdk-8u161-linux-x64.tar.gz 配置环境变量
使用vim编辑/etc/profile文件
命令：vim /etc/profile（提示：vim使用方法）
在/etc/profile文件末尾增加以下配置：
export JAVA_HOME=/opt/jdk/jdk1..0_161
export PATH=$PATH:/$JAVA_HOME/bin . 重载/etc/profile这个文件
source /etc/profile . 检验JDK是否安装成功：java -version
[root@VM_0_15_centos jdk1..0_161]# java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) -Bit Server VM (build 25.161-b12, mixed mode) [root@VM_0_15_centos jdk1..0_161]# mvn -v
Apache Maven 3.3. (bb52d8502b132ec0a5a3f4c09453c07478323dc5; --11T00::+:)

[root@VM_0_15_centos jdk1..0_161]#
3.1.3配置jdk环境
为了明确分类 我在 cd/home 目录下创建了一个java目录 在java目录下又创建了 jdk目录
然后使用cp jdk1.8.0. /home/java/jdk/命令 把解压后的jdk1.8.0.121复制到 jdk目录下
如果 cp 命名不行 就采用 mv 命令进行移动mv jdk1.8.0. /home/java/jdk/
3.1.4设置环境变量
注意：在设置环境变量的同时首先要执行该命令 : vi ~/.bashrc
然后以下几行 分步执行：
export JAVA_HOME=/home/java/jdk/jdk1..0_121
export CLASSPATH=${JAVA_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH 3.1..使修改立即生效
执行：source ~/.bashrc 3.1..验证
执行java -version
