一、环境：宿主机：mac os 10.10 虚拟机：virtualbox 4.3.20 虚拟机操作系统：CentOS7-1406Openvswitch 2.3.0二、安装1、安装依赖包：yum -y install openssl-devel wget kernel-devel2、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 - ovswitch4、下载源码：wget http://openvswitch.org/releases/openvswitch-2.3.0.tar.gz5、解压：tar xfz openvswitch-2.3.0.tar.gz6、创建编译目录：mkdir -p ~/rpmbuild/SOURCES7、从spec文件中删除openvswitch-kmod的依赖包，并创建一个新的spec文件：sed 's/openvswitch-kmod, //g' openvswitch-2.3.0/rhel/openvswitch.spec > openvswitch-2.3.0/rhel/openvswitch_no_kmod.spec8、开始编译：rpmbuild -bb --without check ~/openvswitch-2.3.0/rhel/openvswitch_no_kmod.spec可能出现以下错误：error: File /home/ovswitch/rpmbuild/SOURCES/openvswitch-2.3.0.tar.gz: No such file or directory解决办法：cp openvswitch-2.3.0.tar.gz rpmbuild/SOURCES9、退出当前用户使用root： exit10、安装编译生成的rpm文件：yum localinstall /home/ovswitch/rpmbuild/RPMS/x86_64/openvswitch-2.3.0-1.x86_64.rpm11、启动服务：systemctl start openvswitch.service12、查看服务状态：systemctl -l status openvswitch.service可能出现以下错误：openvswitch.service - LSB: Open vSwitch switch Loaded: loaded (/etc/rc.d/init.d/openvswitch) Active: activating (start) since 四 2014-12-04 18:35:32 CST; 1min 30s ago Control: 13694 (openvswitch) CGroup: /system.slice/openvswitch.service ├─13694 /bin/sh /etc/rc.d/init.d/openvswitch start ├─13696 /bin/sh /usr/share/openvswitch/scripts/ovs-ctl start --system-id=random ├─13697 tee -a /var/log/openvswitch/ovs-ctl.log ├─13723 ovs-vswitchd unix:/var/run/openvswitch/db.sock -vconsole:emer -vsyslog:err -vfile:info --mlockall --no-chdir --log-file=/var/log/openvswitch/ovs-vswitchd.log --pidfile=/var/run/openvswitch/ovs-vswitchd.pid --detach --monitor ├─13724 ovs-vswitchd unix:/var/run/openvswitch/db.sock -vconsole:emer -vsyslog:err -vfile:info --mlockall --no-chdir --log-file=/var/log/openvswitch/ovs-vswitchd.log --pidfile=/var/run/openvswitch/ovs-vswitchd.pid --detach --monitor └─13725 ovs-vswitchd unix:/var/run/openvswitch/db.sock -vconsole:emer -vsyslog:err -vfile:info --mlockall --no-chdir --log-file=/var/log/openvswitch/ovs-vswitchd.log --pidfile=/var/run/openvswitch/ovs-vswitchd.pid --detach --monitor12月 04 18:35:33 localhost.localdomain openvswitch[13694]: /etc/openvswitch/conf.db does not exist ...
