深藏阁楼爱情的钟 2022-11-09 01:00 205阅读 0赞

# 1.安装环境 #

DELL R710

Centos 6.4 x86\_64

# 2. 安装步骤 #

## 2.1 安装依赖包 ##

yum install -y gcc gcc-c++ make libtool patch automake openssl openssl-devel rpm-build redhat-rpm-config python-devel 
    yum install -y kernel kernel-devel kernel-debug-devel

## 2.2 安装autoconf ##

wget ftp://alpha.gnu.org/pub/gnu/autoconf/autoconf-2.68b.tar.gz
    tar -zxvf autoconf-2.68b.tar.gz
    cd autoconf-2.68b
    ./configure
    make
    make install

## 2.3 删除Bridge模块 ##

rm -rf /etc/libvirt/qemu/networks/autostart/default.xml 
    ifconfig virbr0 down 
    rmmod bridge

## 2.4 安装openvswitch ##

wget http://openvswitch.org/releases/openvswitch-1.11.0.tar.gz
    mkdir -p /root/rpmbuild/SOURCES
    cp openvswitch-1.11.0.tar.gz /root/rpmbuild/SOURCES
    cd /root/rpmbuild/SOURCES
    tar -zxvf openvswitch-1.11.0.tar.gz

在这里需要对rhel目录下的openvswitch-kmod-rhel6.spec以及openvswitch-kmod-rhel6.spec.in文件进行修改，分别添加%files，如果没有进行添加，后面在进行制作rpm安装包时会报错。

    rm -rf $RPM_BUILD_ROOT

./boot.sh
    ./configure.sh
    make dist

**创建rpm安装包**

rpmbuild -bb rhel/openvswitch.spec
    rpmbuild -bb rhel/openvswitch-kmod-rhel6.spec

此时可以在/root/rpmbuild/RPMS/x86\_64目录下找到4个关于openvswitch的rpm包

**安装openvswitch rpm安装包**

rpm -ivh openvswitch-1.11.0-1.x86_64.rpm openvswitch-kmod-1.11.0-1.el6.x86_64.rpm
    rpm -ivh kmod-openvswitch-1.11.0-1.el6.x86_64.rpm

**启动openvswitch**

modprobe openvswitch
    /etc/init.d/openvswitch start
    Starting ovsdb-server                                      [  OK  ]
    Configuring Open vSwitch system IDs                        [  OK  ]
    Starting ovs-vswitchd                                      [  OK  ]
    Enabling remote OVSDB managers                             [  OK  ]

通过以上操作，就完成了在centos 6.4下openvswitch的安装！
