1、修改主机名/添加别名访问
修改/etc/sysconfig/network中的hostname
NETWORKING=yes
HOSTNAME=dlserver01;
修改/etc/hosts文件
172.16.50.123 dlserver01 # Added by NetworkManager
127.0.0.1 localhost.localdomain localhost
::1 dlserver01 localhost6.localdomain6 localhost6
172.16.50.124 dlserver02
172.16.50.125 dldb01
2、时间设置
date -R
date -s 20140915
date -s 15:57:30
3、jdk
3.1、
/etc/profile
export JAVA_HOME=/usr/lib/jvm/java-7
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
3.2、
chmod 777 bin
source ~/.bashrc
3.3、
java -version
4、tomcat
tar zxvf apache-tomcat-6.0.39.tar.gz
4.1、server.xml 8080 -- 8081
4.2、tomcat-users.xml
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="admin" password="admin" roles="manager"/>
4.2、配置开机自动启动
vi /etc/rc.local
export JAVA_HOME=/usr/lib/jvm/java-7
/dinglicom/tomcat/bin/startup.sh
4.3、其它机器不能访问，开启8080端口或者关闭防火墙
4.3.1、 开启8080端口。
在/ect/sysconfig下编写iptables文件
加入一行
-A RH-Firewall-1-INPUT –m state NEW –m tcp –p tcp –dport 8080 –j ACCEPT
4.3.2、关闭防火墙
(1)关闭立即生效，重启后又开启
service iptables stop
同理：立即开启 service iptable start
(2)重启后生效
chkconfig iptables off
同理：重启后开启 chkconfig service on
5、yum
5.1、http://blog.itpub.net/25313300/viewspace-708509/
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-cron-3.2.29-40.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh yum-cron-3.2.29-40.el6.centos.noarch.rpm rpm -ivh yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
5.2、更新repo文件
mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.repo.bak
vi /etc/yum.repos.d/rhel-debuginfo.repo
内容为：
[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#released updates
[updates]
name=CentOS-$releasever - Updates

6、MySQL（linux下使用yum安装mysql）
1、安装
查看有没有安装过：
yum list installed mysql*
rpm -qa | grep mysql*
查看有没有安装包：
yum list mysql*
安装mysql客户端：
yum install mysql
安装mysql 服务器端：
yum install mysql-server
yum install mysql-devel
2、启动&&停止
数据库字符集设置
mysql配置文件/etc/my.cnf中加入default-character-set=utf8
启动mysql服务：
service mysqld start或者/etc/init.d/mysqld start
停止：
service mysqld stop
2、登录
创建root管理员：
mysqladmin -u root password zxc
登录：
mysql -u root -p输入密码即可。
忘记密码：
service mysqld stop
mysqld_safe --user=root --skip-grant-tables
mysql -u root
use mysql
update user set password=password("new_pass") where user="root";
flush privileges;
3、远程访问
开放防火墙的端口号
mysql增加权限：mysql库中的user表新增一条记录host为“%”，user为“root”。
4、Linux MySQL的几个重要目录
数据库目录
/var/lib/mysql/
配置文件
/usr/share /mysql（mysql.server命令及配置文件）
相关命令
/usr/bin（mysqladmin mysqldump等命令）
启动脚本
/etc/rc.d/init.d/（启动脚本文件mysql的目录）
