（一）基本操作修改

1. 修改主机名
   vi /etc/sysconfig/network

   NETWORKING=yes
   HOSTNAME=server1.itcast.cn

2. 修改ip地址
   vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.0.101
NETMASK=255.255.255.0

service network restart

1. 修改ip地址和主机名的映射关系
   vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.101 server1.itcast.cn

1. 关闭iptables并设置其开机启动/不启动

   service iptables stop
   chkconfig iptables on
   chkconfig iptables off

（二）安装操作

安装JDK

1. 上传jdk-7u45-linux-x64.tar.gz到Linux上
2. 解压jdk到/usr/local目录
   tar -zxvf jdk-7u45-linux-x64.tar.gz -C /usr/local/

3. 设置环境变量，在/etc/profile文件最后追加相关内容
   vi /etc/profile

   export JAVA_HOME=/usr/local/jdk1.7.0_45
   export PATH=$PATH:$JAVA_HOME/bin

4. 刷新环境变量
   source /etc/profile

5. 测试java命令是否可用
   java -version

安装Tomcat

1. 上传apache-tomcat-7.0.68.tar.gz到Linux上
2. 解压tomcat
   tar -zxvf apache-tomcat-7.0.68.tar.gz -C /usr/local/
3. 启动tomcat
   /usr/local/apache-tomcat-7.0.68/bin/startup.sh
4. 查看tomcat进程是否启动
   jps
   
5. 查看tomcat进程端口
   netstat -anpt | grep 2465
6. 通过浏览器访问tomcat
   http://192.168.0.101:8080/
   

安装MySQL

1. 上传MySQL-server-5.5.48-1.linux2.6.x86_64.rpm、MySQL-client-5.5.48-1.linux2.6.x86_64.rpm到Linux上
2. 使用rpm命令安装MySQL-server-5.5.48-1.linux2.6.x86_64.rpm，缺少perl依赖
   rpm -ivh MySQL-server-5.5.48-1.linux2.6.x86_64.rpm
3. 安装perl依赖，上传6个perl相关的rpm包
   
   rpm -ivh perl-*
4. 再安装MySQL-server，rpm包冲突
   rpm -ivh MySQL-server-5.5.48-1.linux2.6.x86_64.rpm
   
5. 卸载冲突的rpm包
   rpm -e mysql-libs-5.1.73-5.el6_6.x86_64 --nodeps
6. 再安装MySQL-client和MySQL-server
   rpm -ivh MySQL-client-5.5.48-1.linux2.6.x86_64.rpm
   rpm -ivh MySQL-server-5.5.48-1.linux2.6.x86_64.rpm
7. 启动MySQL服务，然后初始化MySQL
   service mysql start
   /usr/bin/mysql_secure_installation
8. 测试MySQL
   mysql -u root -p
