使用手动命令执行

[root@fy-jenkins-prod jenkins]# cat /tmp/param.txt 
JENKINS_USER: root
JENKINS_PID_FILE: /var/run/jenkins.pid
JENKINS_JAVA_CMD: /usr/java/jdk1.8.0_221/bin/java
JENKINS_JAVA_OPTIONS: -Djava.awt.headless=true -Xms8g -Xmx8g -Xmn1g
JENKINS_HOME: /data/jenkins20221130
JENKINS_WAR: /usr/lib/jenkins/jenkins.war
PARAMS: --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=9998 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20


#上面是从脚本中获取的参数，后面使用之后将脚本中输出命令注释掉
#小技巧将jenkins中的命令提问给deepseek，再将参数提供，让它生成下面的命令

sudo -u root /usr/java/jdk1.8.0_221/bin/java -Djava.awt.headless=true -Xms8g -Xmx8g -Xmn1g -DJENKINS_HOME=/data/jenkins20221130 -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=9998 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20

在这里插入图片描述

发现内存不足，改为4g，正常

sudo -u root /usr/java/jdk1.8.0_221/bin/java -Djava.awt.headless=true -Xms4g -Xmx4g -Xmn1g -DJENKINS_HOME=/data/jenkins20221130 -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=9998 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20

修改 /etc/rc.d/init.d/jenkins文件配置的/etc/sysconfig/jenkins配置文件，将Java启动参数的8g改为4g
