1.下载apache-tomcat-9.0.2.tar.gz安装文件
wget http://apache.mirror.rafal.ca/tomcat/tomcat-9/v9.0.2/bin/apache-tomcat-9.0.2.tar.gz
2.解压文件
tar -xzvf apache-tomcat-9.0.2.tar.gz
3.重命名为tomcat，并移到/usr/local/下
mv apache-tomcat-9.0.2 tomcat
mv tomcat /usr/local/
4.在/usr/lib/systemd/system下新增tomcat.service
vi /usr/lib/systemd/system/tomcat.service
内容如下所示：
[Unit]
Description=Apache Tomcat 9
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/tomcat/tomcat.pid
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
User=tomcat
Group=tomcat
[Install]
WantedBy=multi-user.target
5.重载一下服务单元
systemctl daemon-reload
6.在/usr/local/tomcat/bin目录下创建setenv.sh 配置，catalina.sh启动的时候会调用，同时配置java内存参数
vi /usr/local/tomcat/bin/setenv.sh
添加内容如下：
#add java env
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-1.b12.el7_4.x86_64
export JRE_HOME=$JAVA_HOME/jre
#add tomcat pid
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
#add java opts
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"
7.授权
groupadd tomcat
useradd -g tomcat tomcat
chown -R tomcat:tomcat /usr/local/tomcat
8.管理tomcat服务
#配置开机启动
systemctl enable tomcat
#启动tomcat
systemctl start tomcat
#停止tomcat
systemctl stop tomcat
#重启tomcat
systemctl restart tomcat
#查看tomcat状态
systemctl status tomcat
#查看控制台
tail -f -n 200 /usr/local/tomcat/logs/catalina.out
9.开放端口
systemctl start firewalld
systemctl enable firewalld
firewall-cmd --permanent --zone=public --add-port=8080/tcp
firewall-cmd --reload
firewall-cmd --list-all
