　　在这个微服务盛行的时代，docker获得了巨大的成功，因为我们需要在一台服务器装上N个服务。

　　本文不是想讨论如何使用docker，而是，在一台服务器安装了多个服务后，怎样启动方便的启动服务呢？

一、在tomcat的时代中，直接使用tomcat的启动停止命令，轻松搞定，（tomcat的启动脚本很有水平，感兴趣的点开'+'号查看源码学习下吧）

#!/bin/ JAVA_OPTS="$JAVA_OPTS -server -XX:PermSize=128M -XX:MaxPermSize=512m"
CATALINA_PID=/opt/tomcat7/pid.log
CATALINA_HOME=/opt/tomcat7

OS specific support. $var must be set to either true or false.

cygwin=false
darwin=false
os400=false
case "uname" in
CYGWIN) cygwin=true;;
Darwin) darwin=true;;
OS400*) os400=true;;
esac

resolve links - $0 may be a softlink

PRG="$0"

while [ -h "$PRG" ]; do
ls=ls -ld "$PRG"
link=expr "$ls" : '.*-> $.*$$'
if expr "$link" : '/.*' > /dev/null; then
PRG="$link"
else
PRG=dirname "$PRG"/"$link"
fi
done

Get standard environment variables

PRGDIR=dirname "$PRG"

Only set CATALINA_HOME if not already set

[ -z "$CATALINA_HOME" ] && CATALINA_HOME=cd "$PRGDIR/.." >/dev/null; pwd

Copy CATALINA_BASE from CATALINA_HOME if not already set

[ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME"

Ensure that any user defined CLASSPATH variables are not used on startup,# but allow them to be specified in setenv.sh,in rare case when it is needed.

CLASSPATH=

if [ -r "$CATALINA_BASE/bin/setenv.sh" ]; then
. "$CATALINA_BASE/bin/setenv.sh"
elif [ -r "$CATALINA_HOME/bin/setenv.sh" ]; then
. "$CATALINA_HOME/bin/setenv.sh"
fi

For Cygwin,ensure paths are in UNIX format before anything is touched

if $cygwin; then
[ -n "$JAVA_HOME" ] && JAVA_HOME=cygpath --unix "$JAVA_HOME"
[ -n "$JRE_HOME" ] && JRE_HOME=cygpath --unix "$JRE_HOME"
[ -n "$CATALINA_HOME" ] && CATALINA_HOME=cygpath --unix "$CATALINA_HOME"
[ -n "$CATALINA_BASE" ] && CATALINA_BASE=cygpath --unix "$CATALINA_BASE"
[ -n "$CLASSPATH" ] && CLASSPATH=cygpath --path --unix "$CLASSPATH"
fi

For OS400

if $os400; then

Set job priority to standard for interactive (interactive - 6) by using

the interactive priority - 6,the helper threads that respond to requests

will be running at the same priority as interactive jobs.

COMMAND='chgjob job('$JOBNAME') runpty(6)'
system $COMMAND

Enable multi threading

export QIBM_MULTI_THREADED=Y
fi

Get standard Java environment variables

if $os400; then

-r will Only work on the os400 if the files are:

1. owned by the user

2. owned by the PRIMARY group of the user

this will not work if the user belongs in secondary groups

. "$CATALINA_HOME"/bin/setclasspath.sh
else
if [ -r "$CATALINA_HOME"/bin/setclasspath.sh ]; then
. "$CATALINA_HOME"/bin/setclasspath.sh
else
echo "Cannot find $CATALINA_HOME/bin/setclasspath.sh"
echo "This file is needed to run this program"
exit 1
fi
fi

Add on extra jar files to CLASSPATH

if [ ! -z "$CLASSPATH" ] ; then
CLASSPATH="$CLASSPATH":
fi
CLASSPATH="$CLASSPATH""$CATALINA_HOME"/bin/bootstrap.jar

if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
fi

if [ -z "$CATALINA_TMPDIR" ] ; then

Define the java.io.tmpdir to use for Catalina

CATALINA_TMPDIR="$CATALINA_BASE"/temp
fi

Add tomcat-juli.jar to classpath

tomcat-juli.jar can be over-ridden per instance

if [ -r "$CATALINA_BASE/bin/tomcat-juli.jar" ] ; then
CLASSPATH=$CLASSPATH:$CATALINA_BASE/bin/tomcat-juli.jar
else
CLASSPATH=$CLASSPATH:$CATALINA_HOME/bin/tomcat-juli.jar
fi

Bugzilla 37848: When no TTY is available,don't output to console

have_tty=0
if [ "tty" != "not a tty" ]; then
have_tty=1
fi

For Cygwin,switch paths to Windows format before running java

if $cygwin; then
JAVA_HOME=cygpath --absolute --windows "$JAVA_HOME"
JRE_HOME=cygpath --absolute --windows "$JRE_HOME"
CATALINA_HOME=cygpath --absolute --windows "$CATALINA_HOME"
CATALINA_BASE=cygpath --absolute --windows "$CATALINA_BASE"
CATALINA_TMPDIR=cygpath --absolute --windows "$CATALINA_TMPDIR"
CLASSPATH=cygpath --path --windows "$CLASSPATH"
JAVA_ENDORSED_DIRS=cygpath --path --windows "$JAVA_ENDORSED_DIRS"
fi

Set juli LogManager config file if it is present and an override has not been issued

if [ -z "$LOGGING_CONFIG" ]; then
if [ -r "$CATALINA_BASE"/conf/logging.properties ]; then
LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties"
else

二、在jar包盛行的时代，需要为各个jar包写一个启动脚本，如下：

　　shell 脚本确实很方便，虽然这会涉及到另一个专业领域的东西，但是自已使用一下也很安逸呢~

　　尤其在排查问题时， shell方面的知识往往会帮自己很大的忙。

<span style="color: #0000ff">if [ x<span style="color: #800000">"<span style="color: #800000">$PATH_PWD<span style="color: #800000">" == x<span style="color: #800000">"<span style="color: #800000">$PATH_LOCATION<span style="color: #800000">" ];<span style="color: #0000ff">then<span style="color: #000000">

<span style="color: #0000ff">fi

<span style="color: #0000ff">if [ -f ${PATH_TO_JAR} ];<span style="color: #0000ff">then<span style="color: #000000">
<span style="color: #0000ff">else
<span style="color: #0000ff">echo <span style="color: #800000">"<span style="color: #800000">${JAR_NAME}.jar doesn't exist in /www/xx/webapps/${JAR_NAME}/<span style="color: #800000">"<span style="color: #000000">;
exit <span style="color: #800080">1<span style="color: #000000">;
<span style="color: #0000ff">fi<span style="color: #000000">

　　想要将自己写的脚本添加到service命令中，只需将该脚本移动到 /etc/init.d/ 目录下，即可以使用 service xxx command 了。

写一个shell 快速启动停止你的微服务吧
