最近在ubuntu上部署了一個(gè)網(wǎng)站，用的是tomcat但是老部署不成功，提示如下錯(cuò)誤：

后來(lái)在前輩指導(dǎo)下解決了這個(gè)問(wèn)題，有2種可能：
1、ubuntu自帶的JDK問(wèn)題，請(qǐng)重新安裝SUN的JDK #sudo apt-get install sun-java6-jre sun-java6-jdk sun-java6-demo sun-java6-doc sun-java6-source sun-java6-plugin sun-java6-fonts libmyodbc tdsodbc
相關(guān)設(shè)置如下
sudo gedit /etc/profile //這個(gè)配制文件就是一個(gè)純文本的東西，用什么工具自己選擇vi、vim、gvim、emacs什么的都可以，只要是你機(jī)器里有的文本編輯工具就可以
JAVA_HOME=/usr/lib/jvm/java-6-sun
CLASSPATH=.:/usr/lib/jvm/java-6-sun/lib
JRE_HOME=/usr/lib/jvm/java-6-sun/jre
export JRE_HOME
export CLASSPATH
export JAVA_HOME
sudo gedit /etc/environment
JAVA_HOME=/usr/lib/jvm/java-6-sun
CLASSPATH=.:/usr/lib/jvm/java-6-sun/lib
提示：如果要讓它立刻生效可以在終端里輸入： . /etc/environment
一般情況可以不做設(shè)置，因?yàn)樵谶@些安裝完成后，機(jī)器必須得重啟下，所沒(méi)必要設(shè)置，但如果只是設(shè)置一下
環(huán)境變量就要用它的話，就可以采用這種方法。
sudo gedit /etc/jvm
在文件頂部添加
/usr/lib/jvm/java-6-sun
提示：這一步是在設(shè)置JDK的優(yōu)先級(jí)
sudo gedit ~/.bashrc
在文件的末尾，添加如下兩行
export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin
提示：這是在設(shè)置用戶變量
如果您的機(jī)器里裝著多個(gè)JDK用下面的方法來(lái)選擇JDK版本（8.04默認(rèn)是沒(méi)有安裝JDK的，上面的安裝只安裝了一個(gè)版本的JDK，可以不設(shè)置）
sudo update-alternatives --config java
更新當(dāng)前系統(tǒng)的JDK版本
sudo update-java-alternatives -s java-6-sun
然后編輯 #sudo vim /etc/init.d/tomcat6
中找到JDK_DIRS的配置，將其替換為：JDK_DIRS="/usr/lib/jvm/java-6-sun /usr/lib/jvm/java-1.5.0-sun /usr/lib/j2sdk1.5-sun /usr/lib/j2sdk1.5-ibm"
然后重新啟動(dòng)tomcat OK解決了！
2、TOMCAT的安全模式打開(kāi)了
直接編輯#sudo vim /etc/init.d/tomcat6
找到TOMCAT6_SECURITY=Yes 改為no就OK了，重新啟動(dòng)就能運(yùn)行了
