CentOS7下编译安装SPDK iSCSI Target

痛定思痛。 2022-09-29 06:33 265阅读 0赞

# 操作环境 #

Centos 7

# 操作步骤 #

1.下载SPDK

#git clone https://github.com/spdk/spdk.git

2.安装依赖包

# dnf install -y gcc gcc-c++ CUnit-devel libaio-devel openssl-devel

3.下载安装DPDK

#cd spdk
    #wget http://fast.dpdk.org/rel/dpdk-17.02.tar.xz
    #tar xf dpdk-17.02.tar.xz
    #cd dpdk-17.02 && make install T=x86_64-native-linuxapp-gcc DESTDIR=.
    #make DPDK_DIR=./dpdk-17.02/x86_64-native-linuxapp-gcc
    #sudo scripts/setup.sh

4.在安装完成后，我们可以在spdk/app/iscsi\_tgt/目录下面找到iscsi\_tgt可执行文件

![Center][]

5. 编辑iscsi tgt配置文件，可以根据spdk/etc/spdk/iscsi.conf.in文件，进行修改

# iSCSI target configuration file
    #
    # Please write all parameters using ASCII.
    # The parameter must be quoted if it includes whitespace.
    #
    # Configuration syntax:
    # Leading whitespace is ignored.
    # Lines starting with '#' are comments.
    # Lines ending with '\' are concatenated with the next line.
    # Bracketed ([]) names define sections

      #SharedMemoryID 0
    
      # Users can restrict work items to only run on certain cores by
      #  specifying a ReactorMask.  Default is to allow work items to run
      #  on core 0.

      # Tracepoint group mask for spdk trace buffers
      # Default: 0x0 (all tracepoint groups disabled)
      # Set to 0xFFFFFFFFFFFFFFFF to enable all tracepoint groups.
      #TpointGroupMask 0x0
    
      # syslog facility

      # less power. This variable is defined in terms of microseconds. We set default
      # value as 5ms.

    [Rpc]
      # Defines whether to enable configuration via RPC.
      # Default is disabled.  Note that the RPC interface is not
      # authenticated, so users should be careful about enabling
      # RPC in non-trusted environments.
      Enable No
      # Listen address for the RPC service.
      # May be an IP address or an absolute path to a Unix socket.
      Listen 127.0.0.1
    
    # Users must change the PortalGroup section(s) to match the IP addresses
    #  for their environment.
    # PortalGroup sections define which TCP ports the iSCSI server will use
    #  to listen for incoming connections.  These are also used to determine
    #  which targets are accessible over each portal group.

    # NVMe configuration options
    #[Nvme]
    # NVMe Device Whitelist
    # Users may specify which NVMe devices to claim by their PCI

    # argument is a "name" for the device that can be anything. The name
    # is referenced later in the Subsystem section.

    # Alternatively, the user can specify ClaimAllDevices. All
    # NVMe devices will be claimed and named Nvme0, Nvme1, etc.

    # Users may change this section to create a different number or size of
    #  malloc LUNs.
    # If the system has hardware DMA engine, it will use an IOAT
    # (i.e. Crystal Beach DMA) channel to do the copy instead of memcpy.
    # Of course, users can disable offload even it is available.
    #[Malloc]

    #  BlockSize 4096
    
    # Users may not want to use offload even it is available.
    # Users may use the whitelist to initialize specified devices, IDS
    #  uses BUS:DEVICE.FUNCTION to identify each Ioat channel.
    [Ioat]
      Disable Yes
      Whitelist 00:04.0
      Whitelist 00:04.1
