CentOS 下yum安装mysql、jdk和tomcat的方法

  # 使用 yum 安装tomcat 和 mysql   # 创建文件夹   cd /usr/local   mkdir hehe 

  # 1. 安装rzsz   yum list lrzsz*   yum install lrzsz -y 

  # 2. 安装JDK   yum list java*   yum install java-1.7.0-openjdk* -y 

  # 3. 安装mysql   yum list mysql*   yum install mysql-server* -y   # 修改 /etc/my.cnf 设置数据库默认编码以及存储位置,如果可能，优化内存配置   vi /etc/my.cnf 

  [mysqld]   # datadir=/var/lib/mysql   datadir=/usr/local/hehe/mysql_data   socket=/var/lib/mysql/mysql.sock   user=mysql   # Disabling symbolic-links is recommended to prevent assorted security risks   symbolic-links=0   default-character-set=utf8   [mysqld_safe]   log-error=/var/log/mysqld.log   pid-file=/var/run/mysqld/mysqld.pid   [mysql]   default-character-set=utf8 

  :wq 表示写入文件，并退出   :wq! 表示强制写入文件，并退出，适合只读文件什么的。   :q 表示退出不保存

  cd /usr/local/tomcat/conf   # 修改配置文件 server.xml,不能有中文.   # 配置端口号，绑定域名,别名，以及设置线程池，映射context文件夹   vi server.xml 

  <Service name="Catalina">   lt;Executor name="tomcatThreadPool" namePrefix="catalina-exec-"   maxThreads="250" minSpareThreads="20"/>   <Connector port="80" protocol="HTTP/1.1"   connectionTimeout="20000"   redirectPort="8443"   compression="on"   compressionMinSize="2048"   noCompressionUserAgents="gozilla,traviata"   compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,application/json,application/javascript,application/x-javascript"   />   <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" executor="tomcatThreadPool"/>   <Engine name="Catalina" defaultHost="wwwhehe.com">   <Realm className="org.apache.catalina.realm.UserDatabaseRealm"   resourceName="UserDatabase"/>   <Host name="www.hehe.com" appBase="webapps"   unpackWARs="true" autoDeploy="true"   xmlValidation="false" xmlNamespaceAware="false">   <Alias>localhost</Alias>   <Alias>hehe.com</Alias>   <Alias>hehe.cn</Alias>   <Alias>www.hehe.cn</Alias>   <Context docBase="/hehe/upload" path="/upload" />   <Context docBase="/hehe/myapp" path="" />   </Host>   </Engine>   </Service>

  vim /etc/rc.d/rc.local 

  [root@xxx bin]# cat /etc/rc.d/rc.local   #!/bin/sh   #   # This script will be executed *after* all the other init scripts.   # You can put your own initialization stuff in here if you don't   # want to do the full Sys V style init stuff.   touch /var/lock/subsys/local   # start tomcat   /usr/local/tomcat/bin/startup.sh 

  /hehe/myapp
