我已經在Ubuntu服務器上配置了Jenkins，一切工作正常，差不多2個月，Jenkins正在構建作業並運行測試用例。但最近我增加了測試用例的數量。經過一段時間，我開始拒絕連接，當我通過網絡瀏覽器打開詹金斯。Jenkins拒絕連接端口8080
IP：8080發出錯誤「連接被拒絕」。
我試圖重新啓動詹金斯服務：
sudo service jenkins restart
它通常重新啓動，不過，詹金斯並沒有在瀏覽器中打開了。
然後我查·詹金斯的默認設置中/etc/default/jenkins：
# defaults for jenkins continuous integration server
# pulled in from the init script; makes things easier.
NAME=jenkins
# location of java
JAVA=/usr/bin/java
# arguments to pass to java
JAVA_ARGS="-Djava.awt.headless=true" # Allow graphs etc. to work even when an X server is present
JAVA_ARGS="-Xmx1024m"
#JAVA_ARGS="-Djava.net.preferIPv4Stack=true" # make jenkins listen on IPv4 address
PIDFILE=/var/run/$NAME/$NAME.pid
# user and group to be invoked as (default to jenkins)
JENKINS_USER=$NAME
JENKINS_GROUP=$NAME
# location of the jenkins war file
JENKINS_WAR=/usr/share/$NAME/$NAME.war
# jenkins home location
JENKINS_HOME=/var/lib/$NAME
# set this to false if you don't want Hudson to run by itself
# in this set up, you are expected to provide a servlet container
# to host jenkins.

# log location. this may be a syslog facility.priority
JENKINS_LOG=/var/log/$NAME/$NAME.log
#JENKINS_LOG=daemon.info
# OS LIMITS SETUP
# comment this out to observe /etc/security/limits.conf
# this is on by default because http://github.com/jenkinsci/jenkins/commit/2fb288474e980d0e7ff9c4a3b768874835a3e92e
# reported that Ubuntu's PAM configuration doesn't include pam_limits.so, and as a result the # of file
# descriptors are forced to 1024 regardless of /etc/security/limits.conf
MAXOPENFILES=8192
# set the umask to control permission bits of files that Jenkins creates.
# 027 makes files read-only for group and inaccessible for others, which some security sensitive users
# might consider benefitial, especially if Jenkins runs in a box that's used for multiple purposes.
# Beware that 027 permission would interfere with sudo scripts that run on the master (JENKINS-25065.)
#
# Note also that the particularly sensitive part of $JENKINS_HOME (such as credentials) are always
# written without 'others' access. So the umask values only affect job configuration, build records,
# that sort of things.
#
# If commented out, the value from the OS is inherited, which is normally 022 (as of Ubuntu 12.04,
# by default umask comes from pam_umask(8) and /etc/login.defs
# UMASK=027
# port for HTTP connector (default 8080; disable with -1)
HTTP_PORT=8080
# servlet context, important if you want to use apache proxying
PREFIX=/$NAME
# arguments to pass to jenkins.

# --httpPort=$HTTP_PORT (default 8080; disable with -1)
# --httpsPort=$HTTP_PORT

# --prefix=$PREFIX
JENKINS_ARGS="--webroot=/var/cache/$NAME/war --httpPort=$HTTP_PORT"
寄託都似乎罰款在此文件中war文件也有給定的位置。
當我重新啓動服務器3-4次後，它又開始打開了。但是這個問題仍然會一再出現。每次打開Jenkins我都必須重新啓動服務器。
有人可以幫助我找到這個問題，並告訴如何解決它。
也許Java虛擬機內存不足或堆棧空間。日誌說什麼？ – mbieren
我認爲這是服務器資源問題，你是否有像發生這種問題時的情況？ – chenrui
您是否設置了_Manage Jenkins_→_Configure System_→** _ Jenkins位置_ **→_Jenkins URL_正確？如果不匹配，我會看到與您的行爲類似的行爲。 –
