1.检查java版本信息

#java -version
java version "1.7.0_65"
OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)
OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)
|
如果没有则安装,则安装jdk
1.1、(以下方式强烈不建议,因为有时候会缺少jar包,导致tomcat启动不成功):
1
|
yum -y install java-1.7.0-openjdk
|
1.2、强烈建议安装oracle的jdk包,此处安装jdk7,到如下网站下载:http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk7-downloads-1880260.html
下载:jdk-7u79-linux-x64.tar.gz到/tmp
解压:tar xzf jdk-7u79-linux-x64.tar.gz
移动:mv jdk1.7.0_79 /usr/local/java
添加环境变量 vim /etc/profile
,在文件末尾添加:

export JAVA_HOME= /usr/local/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
|
立马生效:source /etc/profile
2. 下载并解压缩tomcat

# cd /tmp
# wget http://apache.fayea.com/tomcat/tomcat-7/v7.0.72/bin/apache-tomcat-7.0.72.tar.gz
# tar xzf apache-tomcat-7.0.72.tar.gz
# mv apache-tomcat-7.0.72 /usr/local/tomcat7
|
3. 启动tomcat
1

|
# cd /usr/local/tomcat7
# ./bin/startup.sh

如果以上命令不行,则进入bin文件夹运行 sh startup.sh
[输出样例]

Using CATALINA_BASE: /usr/local/tomcat7
Using CATALINA_HOME: /usr/local/tomcat7
Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
Using JRE_HOME: /usr/local/java
Using CLASSPATH: /usr/local/tomcat7/bin/bootstrap .jar: /usr/local/tomcat7/bin/tomcat-juli .jar
Tomcat started.

<role rolename= "admin-gui" />
<role rolename= "admin-script" />
<role rolename= "manager-gui" />
<role rolename= "manager-script" />
<role rolename= "manager-jmx" />
<role rolename= "manager-status" />
<user username= "tomcat" password= "tomcat" roles= "manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui" />

6. 重启tomcat服务,进入/usr/local/tomcat7目录

|
# ./bin/shutdown.sh
# ./bin/startup.sh

如果以上命令不行,则进入bin文件夹运行 sh shutdown.sh
或者 sh startup.sh
