一群海豚在属于自己的海滩上自由的玩耍,尽管只是一个方盒的大小,但是设备一样的齐全,同样可以玩的很开心,这就是我今天要说的——MySQL Sandbox2.0,3.0也将要推出。
MySQL Sandbox是一个非常简单快捷部署MySQL技术的一个工具套件,它可以让你在同一台机器上,更加快速的无干扰的去达到你的最终目的,比如,作为软件 测试人员只是要测试软件系统的良好性不需要在mysql的安装上纠缠过多,不需要对MySQL数据库有太多的经验;有的时候我们只是对新版本的一些特性感 兴趣,尽可能快速结束安装部署,而是重点地去体验它的一些特性;可以使用sandbox最短时间部署我们需要的数据库应用架构 (ReplicationCluster),以配合我们的现有的应用系统进行性能测试。
MySQL Sandbox 快速,是用秒来衡量的。下面我们就来感受一下sandbox给我们的F1般的速度,你可以在每次安装前使用time命令统计出real/user/sys三项的使用时间。
安装mysqlsandbox
下载MySQL-Sandbox-3.0.25.tar.gz,
下载mysql-5.x.xx-linux-i686-glibc23.tar.gz
解压mysqlsandbox
tar -xf MySQL-Sandbox-3.0.25.tar.gz -C /mnt
安装简单的几个步骤
perl Makefile.PL
make
make test
make install
开始快速部署mysql
make_sandbox mysql-5.1.42-linux-i686-icc-glibc23.tar.gz
到这里可能会有报错
用export设置变量使ROOT用户可用
export SANDBOX_AS_ROOT=1
最好的做法是写到root用户的 .bash_prefile下
echo>>exportSANDBOX_AS_ROOT=1.bash_profile
然后继续执行make_sandbox
make_sandbox mysql-5.1.42-linux-i686-icc-glibc23.tar.gz

1.Sandbox
The ‘sandbox’ architecture is designed to allow U-Boot to run under Linux on almost any hardware. To achieve this it builds U-Boot (so far as possible) as a normal C application with a main() and normal C libraries.
All of U-Boot’s architecture-specific code therefore cannot be built as part of the sandbox U-Boot. The purpose of running U-Boot under Linux is to test all the generic code, not specific to any one architecture. The idea is to create unit tests which we can run to test this upper level code.
Sandbox configurations includes:
- CONFIG_SANDBOX
- CONFIG_SANDBOX_BIG_ENDIAN
There are two versions of the sandbox:
- 32-bit-wide integers
- 64-bit-wide integers.
Note:by default, the sandbox it built for a 32-bit host. The sandbox using 64-bit-wide integers can only be built on 64-bit hosts.
2.Basic Operation
To run sandbox U-Boot use something like:
$make sandbox_defconfig all $./u-boot
Note: If you get errors about ‘sdl-config: Command not found’ you may need to install libsdl1.2-dev or similar to get SDL support. Alternatively you can build sandbox without SDL (i.e. no display/keyboard support) by removing the CONFIG_SANDBOX_SDL line in include/configs/sandbox.h or using:
#Some machines do not have SDL libraries installed, and it is still useful to build sandbox without LCD/keyboard support. $sudo apt-get install libsdl1.2-dev $make sandbox_defconfig all NO_SDL=1 $./u-boot
U-Boot will start on your computer, showing a sandbox emulation of the serial console: U-Boot 2014.04 (Mar 20 2014 - 19:06:00) DRAM: 128 MiB Using default environment In: serial Out: lcd Err: lcd =>
You can issue commands as your would normally. If the command you want is not supported you can add it to include/configs/sandbox.h.
To exit, type ‘reset’ or press Ctrl-C.
You can use the test-dm.sh:
1 #!/bin/sh 2 3 die() { 4 echo $1 5 exit 1 6 } 7 8 NUM_CPUS=$(cat /proc/cpuinfo |grep -c processor) 9 make O=sandbox sandbox_config || die "Cannot configure U-Boot" 10 make O=sandbox -s -j${NUM_CPUS} || die "Cannot build U-Boot" 11 12 dd if=/dev/zero of=spi.bin bs=1M count=2 13 echo -n "this is a test" > testflash.bin 14 dd if=/dev/zero bs=1M count=4 >>testflash.bin 17 ./sandbox/u-boot -d sandbox/arch/sandbox/dts/test.dtb -i "dm test" 18 #./sandbox/u-boot -d sandbox/arch/sandbox/dts/test.dtb -c "dm test" 19 rm -f spi.bin 20 rm -f testflash.bin
Note:
To execute commands directly, use the -c option. When -c is used, U-Boot exits after the command is complete,but you can force it to go to interactive mode instead with -i.You can use the command below:
Documents/work/code/u-boot/u-boot$ ./sandbox/u-boot -help U-Boot 2019.07-rc3-dirty (May 31 2019 - 19:10:05 +0800) u-boot, a command line test interface to U-Boot Usage: u-boot [options] Options: --show_of_platdata Show of-platdata in SPL -L, --log_level <arg> Set log level (0=panic, 7=debug) -v, --verbose Show test output -t, --terminal <arg> Set terminal to raw/cooked mode -l, --show_lcd Show the sandbox LCD display -n, --ignore_missing Ignore missing state on read -w, --write Write state FDT on exit -r, --read Read the state FDT on startup -s, --state <arg> Specify the sandbox state FDT --rm_memory Remove memory file after reading -m, --memory <arg> Read/write ram_buf memory contents from file -j, --jump <arg> Jumped from previous U-Boot -i, --interactive Enter interactive mode -D, --default_fdt Use the default u-boot.dtb control FDT in U-Boot directory -d, --fdt <arg> Specify U-Boot's control FDT -c, --command <arg> Execute U-Boot command -b, --boot Run distro boot commands -h, --help Display help
2.1.Console / LCD support
Assuming that CONFIG_SANDBOX_SDL is defined when building, you can run the sandbox with LCD and keyboard emulation, using something like:
./u-boot -d u-boot.dtb -l
Note : -l causes the LCD emulation window to be shown.This will start U-Boot with a window showing the contents of the LCD. If that window has the focus then you will be able to type commands as you would on the console. You can adjust display settings in the device tree file - arch/sandbox/dts/sandbox.dts.
3.Supported Drivers
174U-Boot sandbox supports these emulations: 175 176- Block devices 177- Chrome OS EC 178- GPIO 179- Host filesystem (access files on the host from within U-Boot) 180- I2C 181- Keyboard (Chrome OS) 182- LCD 183- Network 184- Serial (for console only) 185- Sound (incomplete - see sandbox_sdl_sound_init() for details) 186- SPI 187- SPI flash 188- TPM (Trusted Platform Module)
There are unfortunately quite a few variants at present:
There are unfortunately quite a few variants at present: 200 201 sandbox - should be used for most tests 202 sandbox64 - special build that forces a 64-bit host 203 sandbox_flattree - builds with dev_read_...() functions defined as inline. 204 We need this build so that we can test those inline functions, and we 205 cannot build with both the inline functions and the non-inline functions 206 since they are named the same. 207 sandbox_noblk - builds without CONFIG_BLK, which means the legacy block 208 drivers are used. We cannot use both the legacy and driver-model block 209 drivers since they implement the same functions 210 sandbox_spl - builds sandbox with SPL support, so you can run spl/u-boot-spl 211 and it will start up and then load ./u-boot. It is also possible to 212 run ./u-boot directly.
4.Testing
U-Boot sandbox can be used to run various tests, mostly in the test/ directory. These include:
401 command_ut 402 - Unit tests for command parsing and handling 403 compression 404 - Unit tests for U-Boot's compression algorithms, useful for 405 security checking. It supports gzip, bzip2, lzma and lzo. 406 driver model 407 - Run this pytest 408 ./test/py/test.py --bd sandbox --build -k ut_dm -v 409 image 410 - Unit tests for images: 411 test/image/test-imagetools.sh - multi-file images 412 test/image/test-fit.py - FIT images 413 tracing 414 - test/trace/test-trace.sh tests the tracing system (see README.trace) 415 verified boot 416 - See test/vboot/vboot_test.sh for this 417
Note: To run all tests use “make check”.
