[root@node01 bin]# ss -lntup | grep 8080

步骤八：开发服务启动脚本
[root@node01 ~]# vim /usr/lib/systemd/system/tomcat.service
[Unit]
Description=Apache Tomcat
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
Environment=JAVA_HOME=/usr/java/jdk1.8.0_261-amd64
Environment=CATALINA_HOME=/usr/local/tomcat
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
测试：
# 要重新加载，不然服务启动不起来
[root@node01 ~]# systemctl daemon-reload
[root@node01 ~]# systemctl restart tomcat.service
[root@node01 ~]# systemctl stop tomcat.service
[root@node01 ~]# ss -lntip | grep 8080
[root@node01 ~]#
[root@node01 ~]#
[root@node01 ~]# systemctl start tomcat
[root@node01 ~]#
[root@node01 ~]# ss -lntip | grep 8080
LISTEN 0 100 [::]:8080 [::]:* users:(("java",pid=38501,fd=51))
[root@node01 ~]# /usr/local/tomcat/bin/shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@node01 ~]# ss -lntpu | grep 8080
[root@node01 ~]#
[root@node01 ~]#
[root@node01 ~]# systemctl restart tomcat.service
[root@node01 ~]#
[root@node01 ~]#
[root@node01 ~]# ss -lntpu | grep 8080
tcp LISTEN 0 100 [::]:8080 [::]:* users:(("java",pid=39970,fd=51))
步骤九：安装数据库，创建数据库并授权用户信息
# 重启数据库，之前的数据库干净环境
[root@node01 ~]# systemctl restart mysqld.service
# 不进入数据库创建数据库并指定字符集
[root@node01 ~]# mysql -uroot -p123456 -e 'create database jpress default character set utf8;'
# 授权用户
[root@node01 ~]# mysql -uroot -p123456 -e 'grant all on jpress.* to jpress@localhost identified by "123456";'
# 查看是否创建成功
[root@node01 ~]# mysql -uroot -p123456 -e 'show databases;'
mysql: [Warning] Using a password on the command line interface can be insecure.

步骤十：上传jpress至根路径，将其移动到/usr/local/tomcat/webapps下
[root@node01 ~]# ll
