二进制安装Tomcat

注意: 安装tomcat 前必须先部署JDK

[root@centos8 ~]#wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.50/bin/apache-tomcat-8.5.50.tar.gz
[root@centos8 ~]#wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.88/bin/apache-tomcat-8.5.88.tar.gz

[root@centos8 ~]#tar xf apache-tomcat-8.5.50.tar.gz -C /usr/local/
[root@centos8 ~]#cd /usr/local/
#建立软连接，目的是为了换版本的时候便利
[root@centos8 local]#ln -s apache-tomcat-8.5.50/ tomcat

[root@centos8 local]# echo 'PATH=/usr/local/tomcat/bin:$PATH' >/etc/profile.d/tomcat.sh

[root@centos8 ~]#. /etc/profile.d/tomcat.sh

请注意你解压以及安装时的路径
配置 tomcat 自启动的 service 文件

#创建tomcat专用帐户
[root@centos8 ~]#useradd -r -s /sbin/nologin tomcat

#准备service文件中相关环境文件
[root@centos8 ~]#vim /usr/local/tomcat/conf/tomcat.conf
[root@centos8 ~]#cat /usr/local/tomcat/conf/tomcat.conf
#两个变量至少设置一项才能启动 tomcat
JAVA_HOME=/usr/local/jdk
#JRE_HOME=/usr/local/jdk/jre

[root@centos8 ~]#vim /lib/systemd/system/tomcat.service
