在linux下安裝好tomcat啟動(dòng)時(shí)報(bào)如下錯(cuò)誤：
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
原因：找不到j(luò)dk或者jre路徑。
解決辦法：在setclasspath.bat的開頭聲明環(huán)境變量，打開tomcat的bin目錄下面的setclasspath.sh，添加粗體部分，路徑修改為自己機(jī)器jdk和jre路徑即可
# -----------------------------------------------------------------------------
#? Set JAVA_HOME or JRE_HOME if not already set, ensure any provided settings
#? are valid and consistent with the selected start-up options and set up the
#? endorsed directory.

export JAVA_HOME=/usr/java/jdk1.8.0_151
export JRE_HOME=/usr/java/jdk1.8.0_151/jre
