Linux服务器,服务管理--systemctl命令详解,设置开机自启动 syetemclt就是service和chkconfig这两个命令的整合,在CentOS 7就开始被使用了。 摘要: systemctl 是系统服务管理器命令,它实际上将 service 和 chkconfig 这两个命令组合到一起。 任务 旧指令 新指令 使某服务自动启动 chkconfig --level 3 httpd on systemctl enable httpd.service 使某服务不自动启动 chkconfig --level 3 httpd off systemctl disable httpd.service 检查服务状态 service httpd status systemctl status httpd.service (服务详细信息) systemctl is-active httpd.service (仅显示是否 Active) 显示所有已启动的服务 chkconfig --list systemctl list-units --type=service 启动某服务 service httpd start systemctl start httpd.service 停止某服务 service httpd stop systemctl stop httpd.service

Cannot mount vagrant synced folder with nfs

问题 I managed to setting up my Symfony2 project inside a ubuntu vagrant box. But it takes around 20 seconds to load the website through it's webserver. After some research, i came up with using nfs for the sync folder. Here're my setting from Vagrantfile: config.vm.network "private_network", ip: "192.168.56.101" config.vm.synced_folder ".", "/vagrant", :nfs => true, :mount_options => ["dmode=777","fmode=777"] After starting de vagrant box i get the following error ==> default: Mounting NFS shared

What's the fastest way to migrate from boot2docker to Vagrant+NFS on Mac OS X?

问题 I have a database container built from the official mysql docker pull mysql . I have a front-end app app built with Cake. I have a back-end app cms built with Symfony. I have container linking set up for both app and cms to start and connect automatically to db . Everything works great but it's super slow with boot2docker. I've been trying to understand how to use Vagrant with NFS. There's a few different tutorials and examples online, but so far I've been unable to get going. I have

Speed up sync latency between host and guest on Vagrant (NFS sync folders)

问题 I'm using vagrant to run a wordpress dev environment on my local machine, have setup nfs as the default file-sharing mechanism (I'm on a mac). Overall performance is really good except for one thing: sync latency. I have set up grunt watchers on the guest to recompile css / javascript as well as livereload the page on every file change. However when I save a file on the host: it takes between 1 and 10 second before syncing on the guest. I'd like to be able to hit save on the host, and see

read() from files - blocking vs. non-blocking behavior

倖福魔咒の 提交于 2019-12-20 04:16:12
问题 Let's assume we opened a file using fopen() and from the file-pointer received, fetch the file-descriptor using fileno() . Then we do lots (>10^8) of random read() s of relativly small chunks, between a size of 4Bytes to 10KBytes from this file: Is it expected behaviour such a read() might return less bytes then requested, without setting errno , if the file-system is an ext3 NFS OCFS2 combination of 2 and 3 ( OCFS2 via NFS ) ? My readings gave me the conclusion it should not be possible for

Is gc.log writing asynchronous? safe to put gc.log on NFS mount?

给你一囗甜甜゛ 提交于 2019-12-20 02:45:35
问题 I heard multiple times that putting gc.log on NFS volume is terrible idea because it might cause gc pauses to be longer. Is it still the case with current jdk (8u25)? 回答1: So I checked - it's not asynchronous and uses regular fopen/fwrite. Relevant code from jdk8u: gcLogFileStream::gcLogFileStream(const char* file_name) { _cur_file_num = 0; _bytes_written = 0L; _file_name = make_log_name(file_name, NULL); // gc log file rotation if (UseGCLogFileRotation && NumberOfGCLogFiles > 1) { char

How does this canonical flock example work?

我们两清 提交于 2019-12-19 08:17:12
问题 When one must synchronize programs (shell scripts) via file system, I have found an flock -based solution to be recommended (should also work on NFS). The canonical example for usage from within a script (from http://linux.die.net/man/1/flock) is: ( flock -s 200 # ... commands executed under lock ... ) 200>/var/lock/mylockfile I don't quite get why this whole construct ensures atomicity. In particular, I am wondering in which order flock -s 200 and 200>/var/lock/mylockfile are executed when e
