tomcat安裝簡單，最主要是tomcat維護和jvm原理理解。
1、建立一個普通賬號
[root@localhost opt]# groupadd gxm [root@localhost opt]# useradd -g gxm gxm
2、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包不需要加環境變量也可以。 [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)
3、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/
4、使用普通賬號啓動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：停止腳本sh tomcat7-1/bin/shutdown.sh
5、如果開啓了firewalld防火牆，則允許8080端口
[root@localhost ~]# firewall-cmd --zone=public --permanent --add-port=8080/tcp [root@localhost ~]# firewall-cmd --reload
6、訪問http://192.168.146.128:8080/驗證
7、多實例部署
