八、安装jdk、tomcat、mysql
   1、安装jdk
       ①卸载自带的jdk
           rpm -qa|grep jdk
           rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
           rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
           rpm -qa|grep jdk
       ②上传并解压jdk
           cd /usr/upload
           tar -zxvf jdk-8u191-linux-x64.tar.gz -C /usr/local
       ③配置环境变量
           vim /etc/profile:
               export JAVA_HOME=/usr/local/jdk1.8.0_191
               export PATH=$PATH:$JAVA_HOME/bin
           source /etc/profile
       ④测试
           java -version
   2、安装tomcat
       ①上传并解压
           cd /usr/upload
           tar -zxvf apache-tomcat-9.0.113.tar.gz -C /usr/local
       ②启动tomcat
           cd /usr/local/apache-tomcat-9.0.113/bin
           ./starup.sh
       ③关闭防火墙
           systemctl status firewalld
           systemctl stop firewalld --停止
           systemctl disable firewalld
       ④测试
           http://192.168.61.129:8080
   3、安装mysql
       ①下载rpm包
           wget http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
       ②安装rpm
           rpm -ivh mysql57-community-release-el7-10.noarch.rpm
       ③安装mysql
           yum -y install mysql-community-server --nogpgcheck
       ④测试
           systemctl start mysqld
           systemctl stop mysqld
           systemctl restart mysqld
           systemctl status mysqld
           systemctl enable mysqld
       ⑤复制密码并登录
           grep password /var/log/mysqld.log
           mysql -u root -p
       ⑥修改密码策略
           mysql> SET GLOBAL validate_password_policy=LOW;
           mysql> SET GLOBAL validate_password_length=4;
       ⑦修改密码
           mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '1111';
       ⑧开启远程登录权限
           mysql> use mysql;
           mysql> select User,Host from user;
           mysql> update user set host ="%" where user = "root";
           mysql> flush privileges;
       ⑨关闭防火墙
           systemctl status firewalld
           systemctl stop firewalld --停止
           systemctl disable firewalld
