2.2 修改主机名、静态IP、关闭防火墙
# 修改主机名未oe151
hostnamectl set-hostname oe151# 设置静态IP
vi /etc/sysconfig/network-scripts/ifcfg-ens33TYPE=Ethernet
BOOTPROTO=static
NAME=ens33
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.10.151
NETMASK=255.255.255.0
GATEWAY=192.168.10.2# 关闭防火墙
systemctl stop firewalld2.3 安装配置httpd
yum install -y httpd
systemctl is-enabled httpdcd /etc/httpd/conf/
vim httpd.conf# If your host doesn't have a ...
ServerName 192.168.10.151:80systemctl start httpd.service
systemctl enable httpd访问测试 http://192.168.10.151
2.4 安装配置MySql
yum install -y mysql5-server
/usr/libexec/mysqld --defaults-file=/etc/my.cnf --user=mysql --initialize
grep "password" /var/log/mysqld.log
systemctl start mysqldmysql -uroot -hlocalhost -p
alter user root@localhost identified by "123123";
flush privileges;create database class;
create table class.m_class(kid int primary key,className char(20));
insert into class.m_class values (1,"class1");
exit;2.5 安装配置JDK
cd /usr/local
tar xf jdk-8u371-linux-x64.tar.gz
ln -s /usr/local/jdk1.8.0_371 /usr/local/jdk
vim /etc/profile# 最后添加 vim 的 G ，按o
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib:/test
export PATH=$JAVA_HOME/bin:$PATHsource /etc/profile
java -version2.6 安装配置Tomcat
cd /usr/local
tar xf apache-tomcat-8.5.88.tar.gzvim /etc/profile# 在最后一行添加
export TOMCAT_HOME=/usr/local/tomcat/usr/local/tomcat/bin/startup.sh# 访问测试：
http://192.168.10.151:8080/cd /usr/local/tomcat/webapps/webapps 目录下放置MyProject1.war项目包，tomcat 会检测到，并自动解压

在 Tomcat 中 安装 jdbc 驱动
将mysql-connector-java-5.1.49.jar放到 /usr/local/tomcat/lib 目录下
修改conn.jsp中url，username，password
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="java.sql.*"%><html>
<head>
<title>通过JSP打开数据表</title>
</head>
<body><%Class.forName("com.mysql.jdbc.Driver"); 驱动程序名String url = "jdbc:mysql://localhost:3306/class"; //数据库名String username = "root"; //数据库用户名String password = "123123"; //数据库用户密码Connection conn = DriverManager.getConnection(url, username, password); //连接状态if(conn != null){out.print("数据库连接成功！");out.print("<br />");Statement stmt = null;ResultSet rs = null;String sql = "SELECT * FROM m_class;"; //查询语句stmt = conn.createStatement();rs = stmt.executeQuery(sql);out.print("查询结果：");out.print("<br />");out.println("kid" + " " + "课程名称 ");out.print("<br />");while (rs.next()) {out.println(rs.getInt("kid")+ "   " + rs.getString("className")); //将查询结果输出out.print("<br />");}}else{out.print("连接失败！");}%>
</body>

重启tomcat 服务
# 重启，先关闭，在启
/usr/local/tomcat/bin/shutdown.sh
