sysbench-0.4.12编译安装和CPU测试例子分享
一、获取安装包
最近的版本为0.4.12,下载地址:
二、编译安装
我的环境为rhel6.2 + mysql 5.6.16,搭建参考上两篇文章<<rhel6.2编译安装mysql 5.6.16>><<mysql benchmark安装dbi组件>>,安装步骤如下:
[root@beanvm ~]# tar -xvf sysbench-0.4.12.tar.gz
[root@beanvm ~]# cd sysbench-0.4.12
[root@beanvm sysbench-0.4.12]# ./configure --with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib && make && make install
因为我的mysql是编译安装的,所以上面需要给出mysql的库文件位置(对应—with—mysql-includes和–with-mysql-libs选项)。
安装过程中常见的报错如下:
../libtool: line 841: x--tag=cc: command not found
../libtool: line 874: libtool: ignoring unknown tag : command not found
../libtool: line 841: x--mode=link: command not found
../libtool: line 1007: *** warning: inferring the mode of operation is deprecated.: command not found
../libtool: line 1008: *** future versions of libtool will require --mode=mode be specified.: command not found
../libtool: line 2234: x-g: command not found
../libtool: line 2234: x-o2: command not found
../libtool: line 1954: x-l/usr/local/mysql/lib: no such file or directory
../libtool: line 2403: xsysbench: command not found
在之前版本中,碰见这个问题我们只需要在编译操作前执行sysbench解压目录下的autogen.sh脚本即可;不过现在这样做还是会报同样的错误,原因是sysbench自带的libtool有问题,我们可以比较它和/usr/bin/libtool文件的区别得知,总之可以通过替换这个libtool文件来解决,或者修改aclocal.m4文件的如下内容
# always use our own libtool.
libtool='$(shell) $(top_builddir)/libtool'
ac_subst(libtool)dnl
将libtool变量的值修改为:'$(shell) /usr/bin/libtool',即使用系统的libtool工具包。
修改后再执行make && make install即可顺利安装。
安装完成马上测试一下:
[root@beanvm sysbench-0.4.12]# sysbench
sysbench: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: no such file or directory
说是缺少libmysqlclient.so.18文件,额,这个文件是存在的,需要手动链接一下:
[root@beanvm ~]# ls -l /usr/local/mysql/lib/libmysqlclient.so.18*
lrwxrwxrwx. 1 mysql mysql 24 feb 15 14:39 /usr/local/mysql/lib/libmysqlclient.so.18 -> libmysqlclient.so.18.1.0
-rwxr-xr-x. 1 mysql mysql 7654927 feb 15 14:30 /usr/local/mysql/lib/libmysqlclient.so.18.1.0
[root@beanvm ~]# ls -l /usr/lib/libmysqlclient.so.18*
ls: cannot access /usr/lib/libmysqlclient.so.18*: no such file or directory
[root@beanvm ~]# ln ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/
部署完成,运行一个cpu基准测试:
[root@beanvm ~]# sysbench --test=cpu --cpu-max-prime=20000 run
