Question

我有一个Vagrant CentOS虚拟机，运行时分配了ps.memory = 2048个RAM。

当我尝试启动puppetserver服务时：

$ puppet --version
4.4.0
$ sudo puppet resource service puppetserver ensure=running
Error: Could not start Service[puppetserver]: Execution of '/bin/systemctl start puppetserver' returned 1: Job for puppetserver.service failed. See 'systemctl status puppetserver.service' and 'journalctl -xn' for details.
Error: /Service[puppetserver]/ensure: change from stopped to running failed: Could not start Service[puppetserver]: Execution of '/bin/systemctl start puppetserver' returned 1: Job for puppetserver.service failed. See 'systemctl status puppetserver.service' and 'journalctl -xn' for details.
service { 'puppetserver':
  ensure => 'stopped',
}
$ journalctl -xn
No journal files were found.
$ systemctl status puppetserver.service
puppetserver.service - puppetserver Service

             └─4755 sleep 1

来自JAVA_ARGS的我的/etc/sysconfig/puppetserver：

JAVA_ARGS="-Xms1g -Xmx1g -XX:MaxPermSize=1g"

根据要求，puppetserver.service文件：

$ cat /usr/lib/systemd/system/puppetserver.service
[Unit]
Description=puppetserver Service
After=syslog.target network.target

[Service]

          -cp "${INSTALL_DIR}/puppet-server-release.jar" clojure.main \
          -m puppetlabs.trapperkeeper.main \
          --config "${CONFIG}" \
          -b "${BOOTSTRAP_CONFIG}" $@

KillMode=process

ExecStartPost=/bin/bash "${INSTALL_DIR}/ezbake-functions.sh" wait_for_app

SuccessExitStatus=143

StandardOutput=syslog

[Install]
WantedBy=multi-user.target

尝试手动运行ExecStartPost命令：

$ /usr/bin/java -Xms1g -Xmx1g -XX:MaxPermSize=1g -XX:OnOutOfMemoryError='kill -9 %%p' -Djava.security.egd=/dev/urandom -cp /opt/puppetlabs/server/apps/puppetserver/puppet-server-release.jar clojure.main -m puppetlabs.trapperkeeper.main --config /etc/puppetlabs/puppetserver/conf.d -b /etc/puppetlabs/puppetserver/bootstrap.cfg

RuntimeError: Got 2 failure(s) while initializing: File[/var/log/puppetlabs/puppetserver]: change from 0700 to 0750 failed: failed to set mode 0700 on /var/log/puppetlabs/puppetserver: Operation not permitted - No message available; File[/var/run/puppetlabs/puppetserver]: change from 0775 to 0755 failed: failed to set mode 0775 on /var/run/puppetlabs/puppetserver: Operation not permitted - No message available

所以我再试一次，但是这次我改变了一些目录权限，但是仍然有类似的错误（考虑到我只是改变了模式，这没有意义吗？）：

$ sudo chown -R vagrant:vagrant /var/run/puppetlabs/
$ sudo chown -R vagrant:vagrant /var/log/puppetlabs/
$ sudo chmod -R 0755 /var/run/puppetlabs/

$ /usr/bin/java -Xms1g -Xmx1g -XX:MaxPermSize=1g -XX:OnOutOfMemoryError='kill -9 %%p' -Djava.security.egd=/dev/urandom -cp /opt/puppetlabs/server/apps/puppetserver/puppet-server-release.jar clojure.main -m puppetlabs.trapperkeeper.main --config /etc/puppetlabs/puppetserver/conf.d -b /etc/puppetlabs/puppetserver/bootstrap.cfg

OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=1g; support was removed in 8.0
RuntimeError: Got 1 failure(s) while initializing: File[/var/run/puppetlabs/puppetserver]: change from 0775 to 0755 failed: failed to set mode 0775 on /var/run/puppetlabs/puppetserver: Operation not permitted - No message available

可能是什么问题？

Answer 1

您确定它是OnOutOfMemory错误吗？我问，因为我发现最新的PuppetServer包含更新版本的logback，如/ var / log / messages中的此消息所示：

Mar 18 01:56:21 puppetserver java: Exception in thread "main" java.lang.AbstractMethodError: ch.qos.logback.core.net.SyslogAppenderBase.createOutputStream()Lch/qos/logback/core/net/SyslogOutputStream;
Mar 18 01:56:21 puppetserver java: at ch.qos.logback.core.net.SyslogAppenderBase.start(SyslogAppenderBase.java:62)
Mar 18 01:56:21 puppetserver java: at ch.qos.logback.classic.net.SyslogAppender.start(SyslogAppender.java:48)

如果你看到，这将用“core.net.Syslog”替换logback.xml中的“classic.net.Syslog”

sed -i_old -e 's/classic.net.Syslog/core.net.Syslog/' /etc/puppetlabs/puppetserver/logback.xml

如果这不是问题，请发布您的日志文件。

Answer 2

您已将日志提供为

OpenJDK 64位服务器VM警告：忽略选项MaxPermSize = 1g; 支持已在8.0中删除

所以，很明显你使用的是jdk 8来移除permgen空间。

永久生成（PermGen）空间已被完全删除，并被一个名为Metaspace的新空间所取代。删除PermGen的后果是显然会忽略PermSize和MaxPermSize JVM参数，并且永远不会得到java.lang.OutOfMemoryError: PermGen error。

因此，请从位置-XX:MaxPermSize=1g

JAVA_ARGS

/etc/sysconfig/puppetserver

JAVA_ARGS =＆＃34; -Xms1g -Xmx1g＆＃34;

所以

然后，

你的命令如下所示：

$ /usr/bin/java -Xms1g -Xmx1g -XX:OnOutOfMemoryError='kill -9 %%p' -Djava.security.egd=/dev/urandom -cp /opt/puppetlabs/server/apps/puppetserver/puppet-server-release.jar clojure.main -m puppetlabs.trapperkeeper.main --config /etc/puppetlabs/puppetserver/conf.d -b /etc/puppetlabs/puppetserver/bootstrap.cfg

或

$ /usr/bin/java -Xms1g -Xmx1g -Djava.security.egd=/dev/urandom -cp /opt/puppetlabs/server/apps/puppetserver/puppet-server-release.jar clojure.main -m puppetlabs.trapperkeeper.main --config /etc/puppetlabs/puppetserver/conf.d -b /etc/puppetlabs/puppetserver/bootstrap.cfg

请尝试这两个命令。我希望两者都能成功运行。为了谨慎起见，我添加了两个。

N.B：无需更改文件权限。在你使用之前保持它们。

否则，如果您不想更改任何内容，可以将java 8降级为java 7

@lollercoster，您开始使用以下服务：

sudo puppet resource service puppetserver ensure=running

但你的下一个命令并没有告诉它是哪个用户

/usr/bin/java -Xms1g -Xmx1g -XX:MaxPermSize=1g -XX:OnOutOfMemoryError='kill -9 %%p' -Djava.security.egd=/dev/urandom -cp /opt/puppetlabs/server/apps/puppetserver/puppet-server-release.jar clojure.main -m puppetlabs.trapperkeeper.main --config /etc/puppetlabs/puppetserver/conf.d -b /etc/puppetlabs/puppetserver/bootstrap.cfg

请在运行上述命令之前直接运行whoami：

whoami
/usr/bin/java -Xms1g -Xmx1g -XX:MaxPermSize=1g -XX:OnOutOfMemoryError='kill -9 %%p' -Djava.security.egd=/dev/urandom -cp /opt/puppetlabs/server/apps/puppetserver/puppet-server-release.jar clojure.main -m puppetlabs.trapperkeeper.main --config /etc/puppetlabs/puppetserver/conf.d -b /etc/puppetlabs/puppetserver/bootstrap.cfg

为什么这个命令？我非常有信心您的问题是权限/用户上下文问题，以下命令会使问题更严重：

$ sudo chown -R vagrant:vagrant /var/run/puppetlabs/
$ sudo chown -R vagrant:vagrant /var/log/puppetlabs/
$ sudo chmod -R 0755 /var/run/puppetlabs/

对于上述情况，您必须在正确的用户上下文中执行sudo以使文件可写，但这取决于其他数据是否可写。所以你可以尝试一下，但我会使用为服务创建的木偶用户

User=puppet

所以你的木偶服务作为用户木偶运行，但你的日志文件是在流浪者用户控制之下，而不是木偶用户可写的。

所以我也会尝试切换回：

$ sudo chown -R puppet /var/run/puppetlabs/
$ sudo chown -R puppet /var/log/puppetlabs/
$ sudo chmod -R 0755 /var/run/puppetlabs/

<强>爪哇

另外，我建议你不要乱用JVM堆参数，除非你知道你做了什么。因为自JDK5以来您不需要在Java VM堆上强制执行较低和最大限制。我只会限制上限

-Xmx1g

javaVM将很好地管理堆和实际分配的mem。由于JVM需要更多，它将逐步增加堆并保持所需的大小（不会缩小到较低的值）。因此，您的计算机上将使用更好的RAM。

另请切换到Oracle JVM。我经常遇到与OpenJDK的安全性和兼容性问题。所以我的第一个测试是在最新所需的Oracle JDK上运行它。在您的情况下Oracle JDK8。但请先尝试我之前提到的许可事项。

祝你好运，请让我更新。

Answer 4

我以前见过这种行为。 不要尝试以root身份手动运行命令，因为您将搞乱权限。而是使用journalctl -xe仔细阅读日志，并尝试了解服务失败的原因。在我的情况下，我无法启动puppetserver服务，因为已经有一个私钥，但还没有公共证书。

ls /etc/puppetlabs/puppet/ssl/certs/`hostname -f`.pem
ls /etc/puppetlabs/puppet/ssl/private_keys/`hostname -f`.pem

如果其中一个没有另一个，则该服务将无法启动。您将在日志文件中看到类似的内容：

Exception in thread "main" java.lang.IllegalStateException: Cannot initialize master with partial state; need all files or none.

如果您是第一次尝试安装puppetserver，那么就无法破坏现有部署，那么您可以删除现有的私钥，puppetserver将自动生成新的一对。

rm /etc/puppetlabs/puppet/ssl/certs/`hostname -f`.pem
rm /etc/puppetlabs/puppet/ssl/private_keys/`hostname -f`.pem

最后再次尝试启动puppetserver服务。

service puppetserver start

Answer 5

/usr/bin/java -Xms1g -Xmx1g -XX:MaxPermSize=1g

Xms和Xms小于MaxPermSize。这对我有用。
