    Mycat 基础7

    这是由于没指定数据源产生的报错 虽然没有连接任何数据库,但从操作体验上来看,与直接操作一个mysql没有什么区别 Tip: 为什么用户名和密码是 test 呢,因为 conf/server.xml 有定义 <user name="test"> <property name="password">test</property> <property name="schemas">TESTDB</property> </user> <user name="user"> <property name="pas

    Docker 基础7

    为了避免只能使用sudo来调用Docker,在软件安装过程中自动创建了docker组,并且在docker进程启动时赋权给了这个组的用户以docker socket的读写权限,所以只用将管理用户加入到docker组,就可以对docker进行使用了

    fio基础7

    ; -- end job file -- Here we have no global section, as we only have one job defined anyway. We want to use async io here, with a depth of4foreach file. We also increased the buffer size used to32KB and define numjobs to4to fork 4 identical jobs. The result is4 processes each randomly writing to their own 64MB file. Instead ofusing the above job file, you could have given the parameters on the command line. For this case, you would specify: $ fio --name=random-writers --ioengine=libaio --iodepth=4 --rw=randwrite --bs=32k --direct=0 --size=64m --numjobs=4When fio is utilized as a basis ofany reasonably large test suite, it might be desirable toshare a setof standardized settings across multiple job files. Instead of copy/pasting such settings, anysection may pull in an external .fio file with'includefilename' directive, asin the following example: ;-- start job file including.fio -- [global] filename=/tmp/test filesize=1m include glob-include.fio [test] rw=randread bs=4k time_based=1 runtime=10 include test-include.fio ; -- end job file including.fio -- ; -- start job file glob-include.fio -- thread=1 group_reporting=1 ; -- end job file glob-include.fio -- ; -- start job file test-include.fio -- ioengine=libaio iodepth=4 ; -- end job file test-include.fio -- Settings pulled into a section apply to that section only (except global section). Include directives may be nested in that any included file may contain further include directive(s). Include files may not contain [] sections. 4.1 Environment variables ------------------------- fio also supports environment variable expansion in job files. Any sub-string of the form "${VARNAME}" as part of an option value (in other words, on the right of the `='),willbeexpandedtothevalueoftheenvironmentvariablecalledVARNAME.Ifnosuchenvironmentvariableisdefined,orVARNAMEistheemptystring,theemptystringwillbesubstituted.Asanexample,let's look at a sample fio invocation and job file: $ SIZE=64m NUMJOBS=4 fio jobfile.fio ; -- start job file -- [random-writers] rw=randwr
