[CentOS7]安装tomcat并开启自启动
安装jdk
1、CentOS 6.X 和 7.X 自带有OpenJDK runtime environment (openjdk)。它是一个在linux上实现开源的Java 平台。
yum search java | grep -i --color JDK
2、在CentOS linux安装 JAVA SDK 在命令行终端以root用户 输入以下命令yum安装 OpenSDK :
yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel #安装openjdk
3、配置环境变量
编辑
vi /etc/profile
写入:
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export CLASSPATH=$JAVA_HOME/lib/*.* export PATH=$PATH:$JAVA_HOME/bin
生效:
source /etc/profile #让设置立即生效。
确认是否成功:
echo $JAVA_HOME
echo $CLASSPATH
echo $PATH
4、查看是否安装成功
java -version
安装tomcat
1、安装wget
yum install wget
2、下载、解压安装tomcat
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.13/bin/apache-tomcat-9.0.13.tar.gz tar xvf apache-tomcat-9.0.13.tar.gz -C /usr/local/ ## 解压 mv /usr/local/apache-tomcat-9.0.13/ /usr/local/tomcat/ ##剪切到tomcat目录下
3、 把startup.sh和shutdown.sh这两个脚本里的最前面加上下面一段:
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export TOMCAT_HOME=/usr/local/tomcat export CATALINA_HOME=/usr/local/tomcat export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar export PATH=$PATH:/usr/local/java/bin:/usr/local/tomcat/bin
4、启动tomcat
/usr/local/tomcat/bin/startup.sh
5、开放默认端口8080
firewall-cmd --zone=public --add-port=8080/tcp --permanent #重启 systemctl restart firewalld.service #重新加载载 firewall-cmd --reload
6、浏览器中访问http://192.168/226/129:8080,出现下面页面,证明安装成功
7、设置开机自启
vi /etc/rc.d/init.d/tomcat
写入以下内容:
#!/bin/bash # # kenny [email protected] # /etc/rc.d/init.d/tomcat # init script for tomcat precesses # # processname: tomcat # description: tomcat is a j2se server # chkconfig: 2345 86 16 # description: Start up the Tomcat servlet engine. if [ -f /etc/init.d/functions ]; then . /etc/init.d/functions elif [ -f /etc/rc.d/init.d/functions ]; then . /etc/rc.d/init.d/functions else echo -e "/atomcat: unable to locate functions lib. Cannot continue." exit -1 fi RETVAL=$? CATALINA_HOME="/usr/local/tomcat" case "$1" in start) if [ -f $CATALINA_HOME/bin/startup.sh ]; then echo $"Starting Tomcat" $CATALINA_HOME/bin/startup.sh fi ;; stop) if [ -f $CATALINA_HOME/bin/shutdown.sh ]; then echo $"Stopping Tomcat" $CATALINA_HOME/bin/shutdown.sh fi ;; *) echo $"Usage: $0 {start|stop}" exit 1 ;; esac exit $RETVAL
8、添加权限,使得脚本文件可执行
chmod 755 /etc/rc.d/init.d/tomcat
9、添加到服务中
chkconfig --add /etc/rc.d/init.d/tomcat
10、在catalina.sh中添加如下内容
#auto startup tomcat config export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export TOMCAT_HOME=/usr/local/tomcat export CATALINA_HOME=/usr/local/tomcat export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar export PATH=$PATH:/usr/local/java/bin:/usr/local/tomcat/bin
重启tomcat
结语
注意环境变量的配置,jdk的路径问题。
