Linux部署Java环境

一. yum安装jdk

(1)

搜索jdk安装包

yum search java|grep jdk

(2)

下载jdk1.8，下载之后默认的目录为： /usr/lib/jvm/

yum install java-1.8.0-openjdk

(3) 输入 java -version 看是否安装成功

二 安装tomcat

(1) 下载安装tomcat（http://tomcat.apache.org/）我这边是下载的apache-tomcat-8.0.50.tar.gz

(2)

解压tar -zxvf apache-tomcat-8.0.50.tar.gz

(3) 创建目录Tomcat 复制到tomcat目录   mkdir /usr/local/tomcat mv apache-tomcat-8.0.50 /usr/local/tomcat/

(4) 启动 ./startup.sh

三 安装mysql

(1) 安装YUM Repo     wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm

(2) 然后进行repo的安装： rpm -ivh mysql57-community-release-el7-9.noarch.rpm

(3) 安装MySQL

yum install mysql-server

systemctl start mysqld #启动MySQL

配置MySQL

获取安装时的临时密码：

grep 'temporary password' /var/log/mysqld.log

 

登录：

mysql -u root -p

登录成功后修改密码：set password=password("yourpassword");

修改权限 标示任何主机能连接
　
　update user set host = '%' where user = 'root';

使用此命令可以让mysql 设置8位简单命令
set global validate_password_policy=0;
