docker skywalking tomcat监控

1.构建包含skywalking 监控包的Tomcat docker镜像

解压 skywalking包

-->>> apache-skywalking-apm-6.6.0.tar.gz

---->> 拷贝 agent目录到Tomcat的bin目录下

---->> 修改agent中监控相关的agent.config文件

修改监听服务项名称：

该命名将会在skywalking的ui项目中显示

修改agent.conf中接受当前监控数据的通信地址：

修改tmocat中的Catalina.sh脚本，保证容器启动的时候去加载监控脚本程序

CATALINA_OPTS="$CATALINA_OPTS -javaagent:/apache-tomcat-8.5.9/bin/agent/skywalking-agent.jar"

测试过的Catalina.sh文件：

# Control Script for the CATALINA Server

# Environment Variable Prerequisites

# Do not set the variables in this script. Instead put them into a script

# setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

# CATALINA_HOME May point at your Catalina "build" directory.

# CATALINA_BASE (Optional) Base directory for resolving dynamic portions

# of a Catalina installation. If not present, resolves to

# the same directory that CATALINA_HOME points to.

# CATALINA_OUT (Optional) Full path to a file where stdout and stderr

# will be redirected.

# Default is $CATALINA_BASE/logs/catalina.out

# CATALINA_OPTS (Optional) Java runtime options used when the "start",

# "run" or "debug" command is executed.

# Include here and not in JAVA_OPTS all options, that should

# only be used by Tomcat itself, not by the stop process,

# the version command etc.

# Examples are heap size, GC logging, JMX ports etc.

# CATALINA_TMPDIR (Optional) Directory path location of temporary directory

# the JVM should use (java.io.tmpdir). Defaults to

# $CATALINA_BASE/temp.

# JAVA_HOME Must point at your Java Development Kit installation.

# Required to run the with the "debug" argument.

# JRE_HOME Must point at your Java Runtime installation.

# Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME

# are both set, JRE_HOME is used.

# JAVA_OPTS (Optional) Java runtime options used when any command

# is executed.

# Include here and not in CATALINA_OPTS all options, that

# should be used by Tomcat and also by the stop process,

# the version command etc.

# Most options should go into CATALINA_OPTS.

# JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start"

# command is executed. The default is "dt_socket".

# JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start"

# command is executed. The default is localhost:8000.

# JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start"

# command is executed. Specifies whether JVM should suspend

# execution immediately after startup. Default is "n".

# JPDA_OPTS (Optional) Java runtime options used when the "jpda start"

# command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,

# and JPDA_SUSPEND are ignored. Thus, all required jpda

# options MUST be specified. The default is:

# -agentlib:jdwp=transport=$JPDA_TRANSPORT,

# address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND

# JSSE_OPTS (Optional) Java runtime options used to control the TLS

# implementation when JSSE is used. Default is:

# "-Djdk.tls.ephemeralDHKeySize=2048"

# CATALINA_PID (Optional) Path of the file which should contains the pid

# of the catalina startup java process, when start (fork) is

# used

# LOGGING_CONFIG (Optional) Override Tomcat's logging config file

# Example (all one line)

# LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties"

# LOGGING_MANAGER (Optional) Override Tomcat's logging manager

# Example (all one line)

# LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"

# UMASK (Optional) Override Tomcat's default UMASK of 0027

# USE_NOHUP (Optional) If set to the string true the start command will

# use nohup so that the Tomcat process will ignore any hangup

# signals. Default is "false" unless running on HP-UX in which

# case the default is "true"

# -----------------------------------------------------------------------------

构建tomcat镜像

docker build -t tomcatskywalking .

2.启动skywalking 本地服务程序（接受远程监控服务调用的程序）

---->修改本地服务程序的相关地址：

skywalking默认12800为rest api通信端口，

默认11800为gRPC api通信端口。这些都可以在配置文件中进行修改

vim /packages/apache-skywalking-apm-bin/webapp/webapp.yml

vim /packages/apache-skywalking-apm-bin/config/application.yml

3.启动skywalking本地服务程序，然后再启动tomcat应用
