Tomcat 部署
1、JDK的安裝
版本：jdk-7-linux-x64.tar.gz
下載：http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-x64.tar.gz
JDK（Java Development Kit）是Sun Microsystems針對Java開發員的產品。自從Java推出以來，JDK已經成爲使用最廣泛的Java SDK。JDK 是整個Java的核心，包括了Java運行環境、Java工具和Java基礎類庫。
1）建立JDK存放的目錄
# mkdir -pv /opt/java/jvm
2）解壓到/opt/java/jvm下
# tar xf jdk-7-linux-x64.tar.gz -C /opt/java/jvm/
# ll /opt/java/jvm/
3）java環境變量設置(vi /etc/profile 在末行加入下面四條)
# vi /etc/profile
JAVA_HOME=/opt/java/jvm/jdk1.7.0
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH JAVA_HOME CLASSPATH CATALINA_HOME
注：表格中是需要輸入的內容
4）執行剛纔的腳本,使配置文件生效
# source /etc/profile
# java -version
Tomcat install
wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.47/bin/apache-tomcat-7.0.47.tar.gz
# tar xf apache-tomcat-7.0.47.tar.gz
# mv apache-tomcat-7.0.47 /opt/tomcat
啓動tomcat
# /opt/tomcat/bin/startup.sh
用瀏覽器訪問本地的8080看到那隻貓就成功了
編寫測試頁面
# cd /opt/tomcat/webapps/ROOT/
# echo '<%= new java.util.Date() %>' > test.jsp
http://ip:8080/test.jsp
看到當前時間就ok了！
關閉tomcat
# /opt/tomcat/bin/shutdown.sh
service管理腳本：
# vim /etc/init.d/tomcat
#!/bin/bash
#
# tomcat7 This shell script takes care of starting and stopping Tomcat
#
# chkconfig: - 80 20
#

# chmod +x /etc/init.d/tomcat
# chkconfig tomcat on
tomcat cronolog 切割
wget http://cronolog.org/download/cronolog-1.6.2.tar.gz
# tar zxvf cronolog-1.6.2.tar.gz
# cd cronolog-1.6.2
# ./configure --prefix=/opt/cronolog
# make
# make install
修改tomcat bin目錄下的catalina.sh文件中的
Java代碼
org.apache.catalina.startup.Bootstrap “$@” start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &
爲
Java代碼 (位置大概在392行左右，修改else後面那個，一般用security啓動)
org.apache.catalina.startup.Bootstrap "$@" start 2>&1 \
| /opt/cronolog/sbin/cronolog "$CATALINA_OUT" >> /dev/null &
# touch "$CATALINA_OUT" 將這行註釋掉
