删除当前系统的jdk
yum remove java*
下载安装包，官网地址https://www.oracle.com/java/technologies/javase-jdk8-downloads.html
我下载的是Linux x64 RPM Package jdk-8u251-linux-x64.rpm，安装：
rpm -ivh jdk-8u231-linux-x64.rpm
安装完成后添加环境变量：
[root@localhost share]# vim /etc/profile
在最后添加如下内容：
JAVA_HOME=/usr/java/jdk1.8.0_231-amd64
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH
使配置生效：
source /etc/profile

这有个坑，点击最上方的官方下载通道死活下载不下来，建议点击下面的IBMCloud下载，不过下载速度太慢了，我这边上传个网盘
百度盘 提取码：tuw6
解压后进入目录，运行
./eclipse
自动弹出窗口
自定义工作目录后即可进入
到此eclipse安装完毕
官方下载地址https://dev.mysql.com/downloads/mysql/
百度盘 提取码：uu7o
解压后使用yum安装，可自动解决依赖问题：
yum install -y mysql-co*
启动数据库，开机自启：
systemctl start mysqld.service
systemctl enable mysqld.service
直接登陆是登不上去的，需要查看系统自动生成的密码：
vim /var/log/mysqld.log 2020-05-11T08:28:40.795461Z 0 [System] [MY-013169] [Server] /usr/sbin/mysqld (mysqld 8.0.20) initializing of server in progress as process 31317 2020-05-11T08:28:40.805569Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started. 2020-05-11T08:28:41.740314Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended. 2020-05-11T08:28:42.726452Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: c6o-k-EsD7lc 2020-05-11T08:28:44.922164Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.20) starting as process 31367 2020-05-11T08:28:44.934474Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
使用该密码登录：
[root@localhost mysql]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

mysql图形化管理工具，https://github.com/dbeaver/dbeaver/releases
百度盘 提取码：aq6u
上传服务器，解压后直接运行即可
./dbeaver
连接数据库时会出现Unable to load authentication plugin ‘caching_sha2_password‘的报错，需要修改
