centos tomcat安装

1.下载tomcat

cd usr/local
wget http://apache.fayea.com/tomcat/tomcat-7/v7.0.70/bin/apache-tomcat-7.0.70.tar.gz

2. 

tar -zxv -f apache-tomcat-7.0.70.tar.gz //解压安装包
rm -rf apache-tomcat-7.0.70.tar.gz //删除压缩包
mv apache-tomcat-7.0.70 tomcat //重命名文件

3.启动tomcat

/usr/local/tomcat/bin/startup.sh

如果出现以下打印信息,说明安装成功

Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.111.x86_64
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

4.关闭tomcat

/usr/local/tomcat/bin/shutdown.sh

在这里我遇到了一个棘手的问题,端口已打开,tomcat已启动,但就是启动失败了

去启动记录中查看启动记录

但看来看去都不知道是什么原因的导致的,最后问大神

因为我使用yum  安装的Jdk

openjdk导致缺少了一些jar包 大神让我装一下oracle jdk

装完后,立马就好了 ！！！ 哎... 心疼。。

下面是安装oracle JDK 流程

安装之前请确认是否已安装了JDK

我的是yum安装的 不是和我一样的,请自行百度删除java JDK 

yum -y remove java-1.7.0-openjdk*

yum -y remove tzdata-java.noarch

1.下载安装JDK

http://www.oracle.com/technetwork/java/javase/downloads/index.html

选择合适的网址

先抓包获取实际下载地址

wget http://download.oracle.com/otn-pub/java/jdk/7u60-b19/jdk-7u65-linux-x64.tar.gz?AuthParam=1406381642_d498d95482a71eaad9c5c240d100e2a0

重命名并解压

 mv jdk-8u101-linux-x64.tar.gz?AuthParam=1471273728_d6cd73c47f6388973c77ebd246240de9 jdk-8u101-linux-x64.tar.gz
 
 tar -xzvf jdk-8u101-linux-x64.tar.gz

移动文件

mv jdk1.8.0_101 /usr/local/java

2.配置环境变量

vi /etc/profile

最后加入代码

export JAVA_HOME=/usr/java
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

退出后保存环境变量

source /etc/profile

检测是否成功

java -version
