Ansible way to stop a service only if it needs to be upgraded

由 ∥☆過路亽．° 提交于 2019-12-31 00:45:15
问题 In an ansible playbook I want to stop MariaDB if an upgrade is needed (restart from the RPM package does not always work in my situation). I'm quite new to ansible. I came up with this: - name: "Check if MariaDB needs to be upgraded" shell: "yum check-update MariaDB-server|grep MariaDB|wc -l" register: needs_update - name: "Stop mysql service" service: name: mysql state: stopped when: needs_update.stdout == "1" Is there a better way to do this then by executing a shell command? When running

问题 I want to use Laravel queue system in my project and I want to run php artisan queue:work permanently on server's background, I did some searches about this and I found a command line which can run it even after quit from ssh terminal but It can be down in some cases and can make terrible problems for me.

(How) Can I use the new C++ 11 ABI with devtoolset-7 on Centos/RHEL?

由 时光怂恿深爱的人放手 提交于 2019-12-28 15:38:09
问题 My goal is to use gcc 7.2 (and clang 6) on Centos 7 to build executables compatible with Centos 7 targets without devtoolset installed but * using the newer C++ ABI *. The newer ABI fixed a couple of deficiencies in the lib that weren't able to be fixed without an ABI change. E.g list::size O(1) Vs O(n), no COW for strings. I speculated on an answer as to why this might not be possible in the following question. -D_GLIBCXX_USE_CXX11_ABI=1 ineffective for devtoolset-7 on CentOS 7 回答1: This

How to install pip in CentOS 7?

由 断了今生、忘了曾经 提交于 2019-12-28 03:20:13
问题 CentOS 7 EPEL now includes Python 3.4: yum install python34 However, when I try that, even though Python 3.4 installs successfully, it doesn't appear to install pip. Which is weird, because pip should be included by default with Python 3.4. which pip3 doesn't find anything, nor does which pip . How do I access pip from the Python 3.4 package in CentOS 7 EPEL release? 回答1: The easiest way I've found to install pip3 (for python3.x packages) on CentOS 7 is: $ sudo yum install python34-setuptools

问题 I have a PHP script that is being called every minute by crontab like this: * * * * * /usr/bin/php /var/www/html/cronjobs/watchdog/watchdogExec.php The script executes a number of other PHP scripts and passes a variable like so: $ccmd = "nohup sudo /usr/bin/php watchdog.php " . $var . " &"; exec($ccmd); When called from a browser, watchdogExec.php runs fine and does its job. However when I added the cronjob, the script is not working and is spamming mails with the following error: No entry
