java - 在centos 7中启动tomcat 7的问题

Question

我尝试在 centos-release-7-4.1708.el7.centos.x86_64 中运行 tomcat 7

这些是遵循的步骤:

yum install java-1.7.0-openjdk-devel java-1.7.0-openjdk

测试是否安装:

echo $JAVA_HOME
/usr/java/jdk/
echo $JRE_HOME
/usr/java/jdk/jre

安装tomcat 7

yum install tomcat tomcat-webapps tomcat-admin-webapps

systemctl stop tomcat
systemctl start tomcat
systemctl enable tomcat

它应该创建一个指向 tomcat.service 的符号链接(symbolic link)，但是没有...

systemctl status tomcat


tomcat.service - Apache Tomcat Web Application Container
   Loaded: loaded (/usr/lib/systemd/system/tomcat.service; enabled; vendor preset: disabled)

/usr/lib/systemd/system 中文件 tomcat.service 的内容

# Systemd unit file for default tomcat
#
# To create clones of this service:
# DO NOTHING, use tomcat@.service instead.

将/etc/tomcat/tomcat.conf中的JAVA_HOME替换为/usr/java/jdk/
