CentOS7にtomcatをインストールするため、以下のようにコマンドを実行しました。

yum install java-1.8.0-openjdk.x86_64
yum install -y tomcat
wget -p /usr/share/tomcat/webapps/ https://github.com/gitbucket/gitbucket/releases/download/4.26.0/gitbucket.war

tomcatを起動させようとするとエラーがでましたが、原因がわかりません。

[root@localhost ~]# systemctl start tomcat
[root@localhost ~]# systemctl status tomcat
