java service wrapper作用,Java Service Wrapper
这个东西我调查了好几天，累啊不过还是没有搞得很清楚，不过也有点收获了
windows的网络上很多 ，不多说了，不过conf/wrapper.conf这个文件差不多的
安装JDK,此处略过。比如你的projecct安装在/usr/local/myP目录中。
使用命令wget下载Java Service Wrapper(目前版本wrapper-linux-x86-32-3.2.3，官网：http://wrapper.tanukisoftware.org),用命令tar -zxvc wrapper-linux-x86-32-3.2.3.tar.gz解压，得到目录wrapper-linux-x86-32-3.2.3，使用ln -s wrapper-linux-x86-32-3.2.3 wrapper给目录wrapper-linux-x86-32-3.2.3建一个名称为wrapper的快捷方式。
复制wrapper\src\bin\sh.script.in到/usr/local/myP/bin目录，重命名为tomcat
复制wrapper\src\conf\wrapper.conf.in到//usr/local/myP/conf目录，重命名为wrapper.conf
复制wrapper\src\lib\lib目录下的所有3个文件到/usr/local/myP/lib目录
复制wrapper\bin目录下的wrapper文件到/usr/local/myP/bin目录
修改/usr/local/myP/bin/tomcat文件
APP_NAME="Servername "
APP_LONG_NAME="Servername Server"
WRAPPER_CMD="./wrapper"
WRAPPER_CONF="../conf/wrapper.conf"

把ln -s /usr/asc/Servername /etc/init.d 注意(/usr/asc/Servername一定要全路径，否则是一个复制的是个无效文件)
/etc/init.d/Appserver start 这样就可以了 测试了
注意：
如果我把wrapper.java.command=%JAVA_HOME%/bin/java
写成系统jdk的全路径 /usr/java/jdk/bin/java
那么 /usr/asc路径下 运行 ./Appserver start 是可以的
其他路径下 运行 service Appserver start 也可以运行.
估计service这个命令 不给他指定JAVA_HOME 可能读不到JAVA_HOME了
这个我也不太清楚
(service Appserver start 会出现
Unable to locate any of the following binaries:
/etc/rc.d/init.d/./wrapper-linux-x86-32
/etc/rc.d/init.d/./wrapper-linux-x86-64
/etc/rc.d/init.d/./wrapper 错误)
或者无法启动jvm(service Appserver console中提示)
