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：http://sourceforge.net/projects/sysbench/

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
sysbench 0.4.12:  multi-threaded system evaluation benchmark
