centos 安装 tomcat

别的都啰里啰唆的说了一大堆，本来很简单的事儿！

建议直接看原文 http://tecadmin.net/steps-to-install-tomcat-server-on-centos-rhel/

Step 1: Check JAVA  （我自己加的：安装java，只要 yum install java-1.7.0-openjdk.x86_64 就ok)

JAVA is the first requirement for Tomcat 7 installation. Make sure you have JAVA SE 6 or Later version installed in your system. Use following command to check if you have java installed already on your system.

# java -version

java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode)

If you do not have java installed, Use any article Install Java 7 or Install Java 8 in RHEL based systems.

Step 2: Download and Extract Tomcat Archive

Download Apache Tomcat archive file from Apache tomcat official download page. You can use below wget command to download it.

# cd /tmp
# wget http://www.us.apache.org/dist/tomcat/tomcat-7/v7.0.56/bin/apache-tomcat-7.0.56.tar.gz

After competed download extract archive file in /tmp directory and move to proper location as per your need. We are placing this under /usr/local directory.

# tar xzf apache-tomcat-7.0.56.tar.gz
# mv apache-tomcat-7.0.56 /usr/local/tomcat7

Step 3: Start Tomcat

Tomcat is very easy to use, There are no need to compile its source. You simple extract the archive and start the tomcat server. Tomcat by default start on port 8080, Make sure no other services are running on same port using ‘telnet localhost 8080′.

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

[Sample Output]

Using CATALINA_BASE:   /usr/local/tomcat7
Using CATALINA_HOME:   /usr/local/tomcat7
Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
Using JRE_HOME:        /opt/jdk1.8.0_05/jre
Using CLASSPATH:       /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
Tomcat started.

Step 4: Access Tomcat in Browser

Tomcat server works on port 8080 default. To access Tomcat on web browser by connecting your server on port 8080.

http://svr2.tecadmin.net:8080

Step 5: Setup User Accounts

Finally we need to create user accounts to secure and access admin/manager pages. Edit conf/tomcat-users.xml file in your editor and paste inside <tomcat-users> </tomcat-users> tags.

<!-- user manager can access only manager section -->
<role rolename="manager-gui" />
<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->
<role rolename="admin-gui" />
<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />

Step 6: Stop Tomcat

Finally if you feel that there are no need of Tomcat in your system, You can simply stop it using below command from tomcat home directory.

 # ./bin/shutdown.sh

I hope above steps will help you to set up Tomcat 7 on your server. Read our next article to Install Tomcat 7 on Ubuntu. Tomcat 8 stable release is also available to download. Read our next article article to Install Tomcat 8 in Linux
