ansible 批量更新filebeat配置文件

流过昼夜 提交于 2021-02-06 15:38:08
一、filebeat准备工作: 1、prod-tomcat 为生产组,使用ansible -ping 可以通 2、生成filebeat配置文件 3、如果执行不成功 ,注意双引号单引号替换 二、下发替换配置文件 ansible prod-tomcat -S -R root -m copy -a 'src=/etc/ansible/file/filebeat.yml dest=/etc/elk/filebeat/filebeat.yml mode=600 owner=root group=root' 三、kill掉filebeat进程 ansible prod-tomcat -S -R root -m shell -a 'pkill filebeat' 四、后台启动filebeat进程 ansible task -m shell -a “chdir=/usr/local/filebeat nohup ./filebeat -e -c filebeat.yml > /dev/null 2>&1 &” 五、查看后台进程 ansible prod-tomcat -S -R root -m shell -a 'ps aux | grep filebeat | grep -v grep' 来源: oschina 链接: https://my.oschina.net/u/4321917/blog

教你在IDEA中配置Git导入的Spring项目

Git项目导入并更新之后,配置Git角色和数据库连接。 配置Project Structure Project 默认配置不需要修改,需要注意的是Project language level要选择和项目使用的jdk版本号一致,点击Apply。 Modules 点击+选择Import Module选择项目文件夹下WebRoot下的.project,点击OK到项目module配置完成。有时候导入Git项目时会默认生成web文件夹在项目中作为module目录,此时须删掉web文件夹。 在导入的module上右击Add一个web,配置web的Deployment Descriptors中的Path为:项目名\WebRoot\WEB-INF\web.xml,Web Resource Directory为:项目名\WebRoot,点击Apply。 Libraries 点击+选择Java,选择:项目名\WebRoot\WEB-INF\lib,选择ok,点击Apply。 Facets 不需要做任何操作。前面配置无误时,在Facets中会出现Web目录。 Artifacts 建议在上面的Libraries的下方点击Create Artifacts创建,<mark>注意:</mark>创建完成后点击下方的Fix,添加上所有缺少的依赖。 另一种创建Artifacts的方法,点击+号Web

Is there a standard way to customize the deploy path in Spring Boot?

China☆狼群 提交于 2021-02-06 11:53:17
问题 I'm exploring the possibilities of Spring Boot right now, and I'm at a slight impasse. I want to be able to run two Spring Boot applications at once, both on the same server, but at different paths (one deploys on / , the other deploys at /another-path ). Because this is an embedded Tomcat instance running within Spring Boot, there's no configuration files available for me to change. Is there a standard way to do this? Is it possible ? 回答1: Spring Boot comes with some pre-built property

管理博文 亿级QPS技术架构如何搭建?阿里全新开源2021高并发技术小册,简直不要太香!

基础 我之前也踩过一些坑, 参与的一个创业项目在初始阶段就采用了服务化的架构,但由于当时人力有限,团队技术积累不足,因此在实际项目开发过程中,发现无法驾驭如此复杂的架构,也出现了问题难以定位、系统整体性能下降等多方面的问题,甚至连系统宕机了都很难追查到根本原因,最后不得不把服务做整合,回归到简单的单体架构中。 所以我建议一般系统的演进过程应该遵循下面的思路: 最简单的系统设计满足业务需求和流量现状,选择最熟悉的技术体系。随着流量的增加和业务的变化,修正架构中存在问题的点,如单点问题,横向扩展问题,性能无法满足需求的组件。在这个过程中,选择社区成熟的、团队熟悉的组件帮助我们解决问题,在社区没有合适解决方案的前提下才会自己造轮子。当对架构的小修小补无法满足需求时,考虑重构、重写等大的调整方式以解决现有的问题。 以淘宝为例, 当时该业务从 0 到 1 的阶段是通过购买的方式快速搭建了系统。而后,随着流量的增长,淘宝做了一系列的技术改造来提升高并发处理能力,比如数据库存储引擎从MyISAM 迁移到 InnoDB,数据库做分库分表,增加缓存,启动中间件研发等。当这些都无法满足时就考虑对整体架构做大规模重构,比如说著名的“五彩石”项目让淘宝的架构从单体演进为服务化架构。正是通过逐步的技术演进,淘宝才进化出如今承担过亿QPS 的技术架构。 下面就为大家展示一份技术小册,需要的朋友点赞收藏

Linux进程管理工具 Supervisor详解

点点圈 提交于 2021-02-05 20:54:47
Supervisor安装与配置(linux/unix进程管理工具) Supervisor( http://supervisord.org )是用Python开发的一个client/server服务,是Linux/Unix系统下的一个进程管理工具,不支持Windows系统。它可以很方便的监听、启动、停止、重启一个或多个进程。用Supervisor管理的进程,当一个进程意外被杀死,supervisort监听到进程死后,会自动将它重新拉起,很方便的做到进程自动恢复的功能,不再需要自己写shell脚本来控制。 因为Supervisor是Python开发的,安装前先检查一下系统否安装了Python2.4以上版本。下面以CentOS7.6,Python2.7.5版本环境下,介绍Supervisor的安装与配置步聚: 实验环境 系统平台 cat /etc/redhat-releaseCentOS Linux release 7.6.1810 (Core) Python版本 python -VPython 2.7.5 如果python版本低于2.6请升级,下面贴出一个安装python3.6.8的安装示例 yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk

Restart Tomcat with Java

问题 I need to restart the tomcat from Java code. For eg, if a query is not executed for a certain time Period then it will restart the tomcat automatically. I have tried the following shutdown and startup code, but when we shutdown the tomcat then the java code will not run and tomcat not started. Note :- I am running this code from a application and restarting the same tomact which the same application is using. Following the code try { PreparedStatement.setQueryTimeout(10); rs =

What do I need to include in Tomcat 7 to get javax.persistence working correctly?

问题 I'm attempting to build a JSF/Hibernate application using Java 7 and Tomcat 7. I have installed the Java SDK and the JavaEE SDK, and copied the javaee.jar and javaee-api-6.jar into my Tomcat LIB folder. By my understanding of this post and this post I should have all of the jars I need, and to the best of my knowledge I have no other jars in this folder that have conflicting resources. The javaee.jar file contains what looks like a Maven pom file, and nothing else. I'm not sure what its value
