tomcat中JDK安装
[iyunv@wangchao ~]# cd /usr/local/src/
[iyunv@wangchaosrc]#wget http://download.oracle.com/otn-p ... 100c587fbae5f08d8cd
[iyunv@wangchaosrc]#mv jdk-8u51-linux-i586.tar.gz\?AuthParam\=1437564943_0e9e4215c41bb100c587fbae5f08d8cd jdk-8u51-linux-i586.tar.gz

CLASSPATH=/usr/local/jdk1.8.0_51/jre/lib:/usr/local/jdk1.8.0_51/lib:/usr/local/jdk1.8.0_51/jre/lib/charsets.jar

[iyunv@wangchao src]# ls /usr/local/jdk1.8.0_51           //查看，确保这些路径存在
root@wangchao src]# ls /usr/local/jdk1.8.0_51/bin
[iyunv@wangchao src]# ls /usr/local/jdk1.8.0_51/jre

[iyunv@wangchao src]# source  /etc/profile.d/java.sh
[iyunv@wangchao src]# java -version              //查看java版本，此版本为系统自安装的、
java version "1.7.0_65"

卸载
[iyunv@wangchao src]# which java
/usr/bin/java
[iyunv@wangchao src]# rpm -qf /usr/bin/java
file /usr/bin/java is not owned by any package
[iyunv@wangchao src]# yum list |grep jdk
[iyunv@wangchao src]# yum remove java-1.7.0-openjdk* java-1.6.0-openjdk*
[iyunv@wangchao src]# java -version
-bash: /usr/bin/java: No such file or directory
//无任何版本信息了

[iyunv@wangchao src]# source  /etc/profile.d/java.sh
[iyunv@wangchao src]# java -version
java version "1.8.0_51"                 //出现此版本信息，说明jdk已安装成功了
tomcat安装
[iyunv@wangchaosrc]#wget http://apache.fayea.com/tomcat/t ... omcat-7.0.63.tar.gz
[iyunv@wangchao src]# ls
apache-tomcat-7.0.63.tar.gz
[iyunv@wangchao src]# tar zxvf apache-tomcat-7.0.63.tar.gz
[iyunv@wangchao src]# mv apache-tomcat-7.0.63 /usr/local/tomcat
[iyunv@wangchao src]# ls /usr/local/tomcat/
[iyunv@wangchao src]# cd /usr/local/tomcat/
[iyunv@wangchao tomcat]# cp -v bin/catalina.sh /etc/init.d/tomcat
[iyunv@wangchao tomcat]# chmod 755 /etc/init.d/tomcat
root@wangchao tomcat]# chkconfig --add tomcat
service tomcat does not support chkconfig              //报错不支持


[iyunv@wangchao tomcat]# vim /etc/init.d/tomcat                    //从第二行加入
# chkconfig: 2345 63 37
# description: tomcat server init script
# Source Function Library
. /etc/init.d/functions
JAVA_HOME=/usr/local/jdk1.8.0_51
CATALINA_HOME=/usr/local/tomcat

[iyunv@wangchao tomcat]# chkconfig --add tomcat
[iyunv@wangchao tomcat]# chkconfig tomcat on
[iyunv@wangchao tomcat]# /etc/init.d/tomcat start

[iyunv@wangchao tomcat]# ps aux |grep tomcat

[iyunv@wangchao tomcat]# /etc/init.d/tomcat stop                //重启需先stop、再start
[iyunv@wangchao tomcat]# /etc/init.d/tomcat start
[iyunv@wangchao tomcat]# iptables -nvL

windows访问192.168.137.22:8080.出现tomcat默认页面





tomcat的优化

[iyunv@wangchao tomcat]# cd /usr/local/tomcat/conf/
[iyunv@wangchao conf]# ls
[iyunv@wangchao conf]# vim server.xml
将<Connector port="8080" protocol="HTTP/1.1"中的8080改成80
//插入：
<Host name="www.123.com" appBase="/data/tomcatweb"
                 unpackWARs="false" autoDeploy="true" xmlValidation="false"
                 xmlNamespaceAware="false">
                <Context path="" docBase="./" debug="0" reloadable="true" crossContext="true"/>
      </Host>

[iyunv@wangchao conf]# mkdir -p /data/tomcatweb
[iyunv@wangchao conf]# /etc/init.d/tomcat stop
[iyunv@wangchao conf]# /etc/init.d/tomcat start
[iyunv@wangchao conf]# ps aux |grep java
root      3576 16.9  4.7 337456 48656 pts/0    Sl   04:36   0:03 /usr/local/jdk1.8.0_51/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/local/tomcat/endorsed -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start
[iyunv@wangchao conf]# netstat -lnp
tcp        0      0 :::80       :::*              LISTEN      3656/java

//监听端口变为80
客户端访问192.168.137.22无需再加8080
