Linux安装Tomcat

安装Java8环境 1.如centos自带了openjdk,请先删除

2.FinalShell连接虚拟机

3.创建Java目录

4.上传jdk

5.解压

6.配置环境变量

JAVA_HOME=/usr/java/jdk1.8.0_151
JRE_HOME=/usr/java/jdk1.8.0_151/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin 
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib 
export JAVA_HOME JRE_HOME PATH CLASSPATH

安装Tomcat 1.下载tar.gz的包，并上传到/usr/local下解压，重命名

• http://tomcat.apache.org/download-80.cgi
  
• 上传
  
• 解压

tar -xvf apache-tomcat-8.5.81.tar.gz

• 重命名

mv apache-tomcat-8.5.81/ tomcat-8.5.81

2.配置环境变量

• vim /etc/profile
  

JAVA_HOME=/usr/java/jdk1.8.0_152
JRE_HOME=/usr/java/jdk1.8.0_151/jre
HADOOP_HOME=/usr/local/hadoop-2.7.1
ZOOKEEPER_HOME=/usr/local/zookeeper-3.3.6
FLUME_HOME=/usr/local/flume-1.9.0
NGINX_HOME=/usr/local/nginx
TOMCAT_HOME=/usr/local/tomcat-8.5.81

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$ZOOKEEPER_HOME/bin:$FLUME_HOME/bin:$NGINX_HOME/sbin:$TOMCAT_HOME/bin
export PATH CLASSPATH JAVA_HOME JRE_HOME HADOOP_HOME ZOOKEEPER_HOME FLUME_HOME NGINX_HOME TOMCAT_HOME

• source /etc/profile

3.测试访问

• startup.sh
  
• web访问：http://192.168.10.100:8080/
  

开机自启动 1.新建启动文件

• vim /usr/lib/systemd/system/tomcat8.service

[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=oneshot
ExecStart=/usr/local/tomcat-8.5.81/bin/startup.sh
ExecStop=/usr/local/tomcat-8.5.81/bin/shutdown.sh
ExecReload=/bin/kill -s HUP $MAINPID
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

2.启动

systemctl enable tomcat8.service

3.其他

• 启动tomcat

systemctl start tomcat8.service

• 关闭tomcat

systemctl stop tomcat8.service

• 重启tomcat

systemctl restart tomcat8.service

---

电脑异常关机之后，所有虚拟机都需要重启，重启后tomcat启动出现问题 1.错误

2.解决

• cd /usr/local/tomcat-8.5.81/bin
• vim catalina.sh

export JAVA_HOME=/usr/java/jdk1.8.0_151
export JRE_HOME=/usr/java/jdk1.8.0_151/jre

• systemctl start tomcat8.service
