MCollective 守护进程未绑定网络套接字

Question 1

问题出在 Java 密钥库上：

pe-activemq 启动正常

$ sudo /etc/init.d/pe-activemq start
 * pe-activemq started

但是通过观察 PS，我注意到 activemq 尝试启动但几乎立即失败。我修改了启动脚本以进行一些调试：

start() {
    echo -n "Starting $APP_NAME... "
    getpid
    if [ "X$pid" = "X" ]
    then
        # original command
        # COMMAND_LINE="$CMDNICE $WRAPPER_CMD $WRAPPER_CONF wrapper.syslog.ident=$APP_NAME wrapper.pidfile=$PIDFILE wrapper.daemonize=TRUE $ANCHORPROP $IGNOREPROP $LOCKPROP"
        # custom command with deamonize=FALSE
        COMMAND_LINE="$CMDNICE $WRAPPER_CMD $WRAPPER_CONF wrapper.syslog.ident=$APP_NAME wrapper.pidfile=$PIDFILE wrapper.daemonize=FALSE $ANCHORPROP $IGNOREPROP $LOCKPROP"
        echo "executing [$COMMAND_LINE]"

启动 pe-activemq 出现以下错误

jvm 1    | ERROR | Failed to start ActiveMQ JMS Message Broker. Reason: java.io.IOException: Transport Connector could not be registered in JMX: Failed to bind to server socket: stomp+ssl://0.0.0.0:61613 due to: java.net.SocketException: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.DefaultSSLContextImpl)

这看起来像是密钥库的问题。/opt/puppet/activemq/conf/activemq-wrapper.conf 配置文件为您提供了以下详细信息：

set.default.ACTIVEMQ_BASE=/opt/puppet/activemq
wrapper.working.dir=/var/log/pe-activemq
[...]
# Enable SSL of the Stomp Connection (Note, this provides encryption only as per #10596)
wrapper.java.additional.7=-Djavax.net.ssl.keyStorePassword=puppet
wrapper.java.additional.8=-Djavax.net.ssl.keyStore=%ACTIVEMQ_BASE%/conf/broker.ks
# The trust store need not be present.
wrapper.java.additional.9=-Djavax.net.ssl.trustStorePassword=puppet
wrapper.java.additional.10=-Djavax.net.ssl.trustStore=%ACTIVEMQ_BASE%/conf/broker.ts

仅供参考，/opt/puppet/activemq/conf 是指向 /etc/puppetlabs/activemq 的符号链接。在该目录中，brochet.ts 文件存在，但缺少 broker.ks

根据此页面（http://activemq.apache.org/how-do-i-use-ssl.html），我做了以下事情

$ cd /etc/puppetlabs/activemq
$ sudo keytool -genkey -alias broker -keyalg RSA -keystore broker.ks
=> provided puppet password everywhere

然后activemq启动正常
