尝试在CentOS 7上启动cosbench遭遇的一些问题

尝试启动cosbench，遭遇报错：

[root]hopisdtmelabs14# cat driver-boot.log                                                                                                                                       /tmp/cosbench/0.4.2/log

看起来像是网络端口18089已经被占用了，杀掉那些进程，问题解决。

但cosbench driver 还是启动不了。

[root]hopisdtmelabs14# bash ./start-driver.sh /tmp/cosbench/cos
Launching osgi framwork ...

which: no nc in (/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/tme/bin:/usr/local/tme/tme_portal/perf_web/bin)
No appropriate tool found to detect cosbench driver status.

看报错，应该是nc（ncat）这个软件没有安装。可是通过yum还没法正常安装。我通过下面的命令解决了这个问题：

# yum -y install wget

# wget https://nmap.org/dist/ncat-7.80-1.x86_64.rpm

# yum localinstall ncat-7.80-1.x86_64.rpm

# cd /usr/bin

# ln -s ncat nc

还是有错误。

# bash ./start-driver.sh                                                                                                                                          /tmp/cosbench/cos

我怀疑是我的java的版本过高，所以卸掉java 8，安装java 7。

# rpm -aq | grep -i jdk /tmp/cosbench/cos
java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64

# rpm -e java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64

# rpm -e java-1.8.0-openjdk-headless-1.8.0.181-3.b13.el7_5.x86_64

# yum remove java

安装java 7.

#yum install java-1.7.0-openjdk

结果遇到了报错，说有两个软件包太旧了，达不到安装的要求。

尝试安装更新，结果还是报错，无法更新。

[Errno 14] HTTP/HTTPS Error 404

于是执行下面的命令，对yum进行修复。

#yum clean all
#rm -rf /var/cache/yum/*

之后java 7也成功安装了。

但还是报错：

经过查询，找到了这篇文章，于是下载了更早的一个版本0.4.2.c4。

终于成功启动了cosbench driver。

# bash ./start-driver.sh                                                                                                                                     /tmp/cosbench/0.4.2.c4
