CentOS7部署tomcat7多實例

tomcat安裝簡單，最主要是tomcat維護和jvm原理理解。

一、創建一個普通帳號

[root@localhost opt]# groupadd gxm
[root@localhost opt]# useradd -g gxm gxm

二、安裝java環境

[root@localhost ~]# wget https://download.oracle.com/otn/java/jdk/7u79-b15/jdk-7u79-linux-x64.rpm（備註：wget下載不了就手動下載）
[root@localhost ~]# rpm -ivh jdk-7u79-linux-x64.rpm

#備註：rpm安裝的java包不須要加環境變量也能夠。
[root@localhost ~]# vim /etc/profile
JAVA_HOME=/usr/java/jdk1.7.0_79
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME
export PATH
export CLASSPATH

[root@localhost ~]# source /etc/profile
[root@localhost ~]# java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

三、安裝tomcat7

[root@localhost ~]# cd /home/gxm
[root@localhost gxm]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.93/bin/apache-tomcat-7.0.93.zip
[root@localhost gxm]# unzip apache-tomcat-7.0.93.zip
[root@localhost gxm]# mv apache-tomcat-7.0.93 tomcat7-1
[root@localhost gxm]# chown -R gxm.gxm tomcat7-1
[root@localhost gxm]# chmod -R 700 tomcat7-1/

四、使用普通帳號啓動tomcat7

[root@localhost gxm]# su - gxm

[gxm@localhost ~]$ sh tomcat7-1/bin/startup.sh
Using CATALINA_BASE:   /home/gxm/tomcat7-1
Using CATALINA_HOME:   /home/gxm/tomcat7-1
Using CATALINA_TMPDIR: /home/gxm/tomcat7-1/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_79
Using CLASSPATH:       /home/gxm/tomcat7-1/bin/bootstrap.jar:/home/gxm/tomcat7-1/bin/tomcat-juli.jar
Tomcat started.

[gxm@localhost ~]$ ps -ef | grep tomcat
gxm        4154      1  9 10:58 pts/0    00:00:02 /usr/java/jdk1.7.0_79/bin/java -Djava.util.logging.config.file=/home/gxm/tomcat7-1/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Dignore.endorsed.dirs= -classpath /home/gxm/tomcat7-1/bin/bootstrap.jar:/home/gxm/tomca7-1/bin/tomcat-juli.jar -Dcatalina.base=/home/gxm/tomcat7-1 -Dcatalina.home=/home/gxm/tomcat7-1 -Djava.io.tmpdir=/home/gxm/tomcat7-1/temp org.apache.catalina.startup.Bootstrap start
gxm        4190   4090  0 10:58 pts/0    00:00:00 grep --color=auto tomcat

[gxm@localhost ~]$ netstat -luntp | grep 8080
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp6       0      0 :::8080                 :::*                    LISTEN      4154/java
備註：中止腳本sh tomcat7-1/bin/shutdown.sh

五、若是開啓了firewalld防火牆，則容許8080端口

[root@localhost ~]# firewall-cmd --zone=public --permanent --add-port=8080/tcp
[root@localhost ~]# firewall-cmd --reload
