CentOS7安装Openvswitch 2.3.0 LTS

1、环境：

宿主机：mac os 10.10 

虚拟机：virtualbox 4.3.20  

虚拟机操作系统：CentOS7⑴406

Openvswitch 2.3.0

2、安装

1、安装依赖包：yum -y install openssl-devel wget kernel-devel

2、安装开发工具：yum groupinstall "Development Tools"

3、添加用户：adduser ovswitch，切换用户并跳转至用户文件夹：su - ovswitch

4、下载源码：wget http://openvswitch.org/releases/openvswitch⑵.3.0.tar.gz

5、解压：tar xfz openvswitch⑵.3.0.tar.gz

6、创建编译目录：mkdir -p ~/rpmbuild/SOURCES

7、从spec文件中删除openvswitch-kmod的依赖包，并创建1个新的spec文件：

sed 's/openvswitch-kmod, //g' openvswitch⑵.3.0/rhel/openvswitch.spec > openvswitch⑵.3.0/rhel/openvswitch_no_kmod.spec

8、开始编译：rpmbuild -bb --without check ~/openvswitch⑵.3.0/rhel/openvswitch_no_kmod.spec

可能出现以下毛病：

error: File /home/ovswitch/rpmbuild/SOURCES/openvswitch⑵.3.0.tar.gz: No such file or directory

解决办法：cp openvswitch⑵.3.0.tar.gz rpmbuild/SOURCES

9、退出当前用户使用root： exit

10、安装编译生成的rpm文件：

yum localinstall /home/ovswitch/rpmbuild/RPMS/x86_64/openvswitch⑵.3.0⑴.x86_64.rpm

11、启动服务：systemctl start openvswitch.service

12、查看服务状态：systemctl -l status openvswitch.service

可能出现以下毛病：

解决办法：

yum install policycoreutils-python.x86_64 0:2.2.5⑴1.el7

mkdir /etc/openvswitch
semanage fcontext -a -t openvswitch_rw_t "/etc/openvswitch(/.*)?"
restorecon -Rv /etc/openvswitch

再次使用:

systemctl stop openvswitch.service

systemctl start openvswitch.service

再次查看服务状态：systemctl -l status openvswitch.service
