centos为我们常用的服务器镜像，熟悉基本环境配置
选用了最常见的 jdk+mysql+tomcat (spring boot +spring cloud)
可选 php + nginx/tomcat + mysql (lavarel)
JDK安装
1 用securefxp传输jdk到/home
2 cd /home
3 cp jdk-8u181-linux-x64.tar.gz /usr/local/
4 cd /usr/local
5 tar xvfz jdk-8u181-linux-x64.tar.gz
6 mv jdk1.8.0_181/ jdk1.8
7 修改环境变量
vi /etc/profile
在末尾添加：
#set javaenvironment
export JAVA_HOME=/usr/local/jdk1.8
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
8让配置生效
source /etc/profile
9 验证
java -version

1 更新源
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
2
yum localinstall mysql57-community-release-el7-8.noarch.rpm
3 安装MySQL
yum install mysql-community-server
6.启动MySQL服务
shell> systemctl start mysqld
7.开机启动
systemctl enable mysqld
systemctl daemon-reload
8.修改root本地登录密码
1）查看mysql密码
grep "temporary password" /var/log/mysqld.log
2）连接mysql
shell> mysql -u root -p
3）修改密码[注意：后面的分号一定要跟上]
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
或者：
mysql> set password for 'root'@'localhost'=password('MyNewPass4!');
