[【原文链接】基于openEuler系统执行Linux内核性能测试脚本（lkp-tests）的流程](http://devops-dev.com/article/451)

（1）若没有openEuler操作系统的虚拟机，则可以参考 [VMware安装openEuler-22.03-LTS版本的虚拟机](http://devops-dev.com/article/420) 安装一台openEuler操作系统的虚拟机

（1）下载lkp-tests测试代码
```bash
cd /opt
git clone https://gitee.com/wu_fengguang/lkp-tests.git
```

（2）安装基础依赖
```bash
cd lkp-tests
make install
```

（3）验证lkp是否安装成功

如下，可以查看到帮助信息，表示lkp已经安装成功了
```bash
[root@openEuler-1 lkp-tests]# lkp help
Usage: lkp <command> [options]

INSTALLATION

install JOB                     install binary dependencies for JOB

JOB

split JOB                       split JOB matrix
        compile JOB                     compile JOB into shell script

TESTING

run JOB                         run test JOB locally
        qemu JOB                        run test JOB in QEMU virtual machine

RESULT

result|rt|_rt|__rt PATTERNs     show result dirs
        ls|ll PATTERNs                  ls result dirs
        rm-path result                  remove result dirs
        _rm PATTERNs                    remove _result dirs

stat [options]                  show result stats
        compare [options]               compare result stats

DEBUG

irb                             run irb with lib/*.rb loaded
        pry                             run pry with lib/*.rb loaded

More commands can be found in /opt/lkp-tests/{bin,sbin,tools}/
[root@openEuler-1 lkp-tests]# 
```

（4）安装lkp-tests的依赖
```bash
lkp install
```

（5）查看当前可执行的任务
```bash
[root@openEuler-1 lkp-tests]# ls jobs/
boot-trace.yaml  borrow-30d.yaml         debug.yaml                  local-tests                      nfs-iozone.yaml         pbzip2.yaml      rdma-pyverbs.yml         send-email.yaml
boot.yaml        build-linux.yaml        hibernate-stress.yaml       mariadb.yaml                     nfs-test.yaml           perf-batch.yaml  README.md                ssh-on-fail.yaml
borrow-10d.yaml  ceph.yaml               hibernate.yaml              multi-docker.yaml                oltp.yaml               pgbench.yaml     replace-repo.yaml        ssh.yaml
borrow-1d.yaml   cgroup2-test.yaml       install-iso-firstboot.yaml  multi-qemu-docker-selftest.yaml  os-matrix-aarch64.yaml  pixz.yaml        rocksdb.yaml             stop_firewalld.yaml
borrow-1h.yaml   cgroup2.yaml            install-iso.yaml            multi-qemu-docker.yaml           os-matrix-dc.yaml       plzip.yaml       secrets_info.yaml        yocto.yaml
borrow-1w.yaml   cluster-ssh-trust.yaml  intel-ipsec-mb              multi-qemu.yaml                  os-matrix-x86.yaml      pxz.yaml         send-email-on-fail.yaml  yum-update.yaml
[root@openEuler-1 lkp-tests]#
```

（6）比如执行 nfs-test.yaml的job，首先分割任务
```bash
[root@openEuler-1 lkp-tests]# lkp split-job jobs/nfs-test.yaml
jobs/nfs-test.yaml => ./nfs-test-30.yaml
[root@openEuler-1 lkp-tests]# 
```

（7）安装子任务的依赖
```bash
[root@openEuler-1 lkp-tests]# lkp split-job jobs/nfs-test.yaml
jobs/nfs-test.yaml => ./nfs-test-30.yaml
[root@openEuler-1 lkp-tests]# lkp install ./nfs-test-30.yaml
make -C /opt/lkp-tests/bin/event
make: 进入目录“/opt/lkp-tests/bin/event”
gcc    -c -o wakeup.o wakeup.c
gcc -static  wakeup.o   -o wakeup
make: 离开目录“/opt/lkp-tests/bin/event”
Installing packages procps-ng
[root@openEuler-1 lkp-tests]#
```

（8）执行子任务
```bash
[root@openEuler-1 lkp-tests]# lkp run ./nfs-test-30.yaml
RESULT_ROOT=/root/.cache/lkp/result/nfs-test/30/0
sleep started
kill 71979 vmstat --timestamp -n 10
kill 71975 dmesg --follow --decode
wait for background processes: 71984 71973 meminfo nfs-hang
Job results saved to /root/.cache/lkp/result/nfs-test/30/0
[root@openEuler-1 lkp-tests]#
```

（9）根据上述提示，执行的结果均存放在 /root/.cache/lkp/result/nfs-test/30/0 目录，主要生成以下文件
```bash
[root@openEuler-1 lkp-tests]# ls /root/.cache/lkp/result/nfs-test/30/0
dmesg.json  job.sh    kmsg       matrix.csv      meminfo.gz       nfs-hang      sleep       sleep.time       stats.csv   time
heartbeat   job.yaml  kmsg.json  matrix.json.gz  meminfo.json.gz  program_list  sleep.json  sleep.time.json  stats.json  time.json
[root@openEuler-1 lkp-tests]#
```
