centos7配置tomcat8详细图文步骤

Posted 2020-08-17

环境描述：
centos7最小安装，配置tomcat8

1.可用本地电脑下载jdk1.8

官网如下，或需要注册Oracle账号登录后才可下载
https://www.oracle.com/technetwork/java/javase/downloads/index.html

2.安装上传工具

[[email protected] ~]# yum -y install lrzsz
上传jdk
[[email protected] ~]# rz

3.jdk上传OK后解压

[[email protected] ~]# ls
anaconda-ks.cfg  jdk-8u201-linux-i586.tar.gz
[[email protected] ~]# tar xf jdk-8u201-linux-i586.tar.gz 
[[email protected] ~]# ls
anaconda-ks.cfg  jdk1.8.0_201  jdk-8u201-linux-i586.tar.gz
[[email protected] ~]# mkdir -p /usr/local/
bin/     etc/     games/   include/ lib/     lib64/   libexec/ sbin/    share/   src/     
[[email protected] ~]# mkdir /usr/local/java
[[email protected] ~]# mv jdk1.8.0_201/* /usr/local/java/

4.jdk环境变量配置

[[email protected] ~]# vim /etc/profile #追加如下变量
export JAVA_HOME=/usr/local/java
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

5.更新profile文件

[[email protected] ~]# source /etc/profile

6.查看java版本

[[email protected] local]# java -version
-bash: /usr/local/java/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: 没有那个文件或目录

出错了：提示没有文件。
此情况应该是最小安装系统缺少相应的库文件导致出错
这里可根据提示安装相应的库文件即可
[[email protected] ~]# yum -y install ld-linux.so.2

[[email protected] ~]# java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) Client VM (build 25.201-b09, mixed mode)
[[email protected] ~]# javac -version
javac 1.8.0_201

安装完提示缺少的文件后，再次查看Java版本，OK。

7.下载tomcat8

官网地址 https://tomcat.apache.org/download-80.cgi
依然下载到本地后再rz上传

8.上传tomcat8并解压

[[email protected] ~]# rz

[[email protected] ~]# ls
anaconda-ks.cfg  apache-tomcat-8.5.41.tar.gz  jdk1.8.0_201  jdk-8u201-linux-i586.tar.gz
[[email protected] ~]# tar xf apache-tomcat-8.5.41.tar.gz 
[[email protected] ~]# ls
anaconda-ks.cfg  apache-tomcat-8.5.41  apache-tomcat-8.5.41.tar.gz  jdk1.8.0_201  jdk-8u201-linux-i586.tar.gz
[[email protected] ~]# mkdir /usr/local/tomcat8
[[email protected] ~]# mv apache-tomcat-8.5.41/* /usr/local/tomcat8/

9.启动tomcat

[[email protected] ~]# /usr/local/tomcat8/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat8
Using CATALINA_HOME:   /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar
Tomcat started.
[[email protected] ~]# ps -ef|grep java
root       9744      1 31 16:44 pts/0    00:00:03 /usr/local/java/bin/java -Djava.util.logging.config.file=/usr/local/tomcat8/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dorg.apache.catalina.security.SecurityListener.UMASK=0027 -Dignore.endorsed.dirs= -classpath /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat8 -Dcatalina.home=/usr/local/tomcat8 -Djava.io.tmpdir=/usr/local/tomcat8/temp org.apache.catalina.startup.Bootstrap start
root       9787   7172  0 16:44 pts/0    00:00:00 grep --color=auto java

启动完成，查看进程OK。

10.页面验证

http://192.168.0.64:8080/

此为防火墙在开启状态，访问被阻，关闭防火墙或者允许页面端口通过都可以。
实验环境可关闭防火墙：

[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

生产环境建议开启端口即可，增强服务器安全性：

[[email protected] tomcat8]# firewall-cmd --permanent --add-port=8080/tcp
success
[[email protected] tomcat8]# firewall-cmd --reload
success

久违的tomcat页面显示OK。
