标签：apt 指定 rem tab 准备 exist soc down 初始化
在ovs学习过程中，如果自己想要安装一个ovs交换机其实一条简单的命令 apt install openvswitch 就可以了，但是这种方法只能安装低版本的ovs。在特殊情况下需要安装指定版本，例如需要下发meters表时需要ovs2.8以上的版本，那么就需要下载安装包手动安装。看似一个复杂的过程，其实也是比较简单的。下面就一起来看看如果手动安装一个指定版本ovs交换机。
准备工作
安装python
[root@localhost ~]# yum -y install python
安装python-pip
如果不安装pip，在下面的过程会报错找不到six模块。
[root@localhost ~]# yum -y install epel*
[root@localhost ~]# yum -y install python-pip
下载指定版本，可以看到这种安装的好处是你可以指定任何一种版本
http://www.openvswitch.org/download/ #下载地址
[root@localhost ~]# tar xf openvswitch-2.8.1.tar.gz
生成makefile文件
[root@localhost ~]# cd openvswitch-2.8.1
[root@localhost openvswitch-2.8.1]# yum -y install python-six
[root@localhost openvswitch-2.8.1]# ./configure
make 编译文件
[root@localhost openvswitch-2.8.1]# make && make install
.检查模块
如果在安装的过程中生成了修改了内核模块，那么重新编译内核。
[root@localhost openvswitch-2.8.1]# make modules_install make: 对“modules_install”无需做任何事。
载入模块，载入openvswitch的模块到内核中
[root@localhost openvswitch-2.8.1]# /sbin/modprobe openvswitch
[root@localhost openvswitch-2.8.1]# /sbin/lsmod |grep openvswitch openvswitch 106996 0 nf_nat_ipv6 14131 1 openvswitch nf_defrag_ipv6 35104 2 openvswitch,nf_conntrack_ipv6 nf_nat_ipv4 14115 2 openvswitch,iptable_nat nf_nat 26787 4 openvswitch,nf_nat_ipv4,nf_nat_ipv6,nf_nat_masquerade_ipv4 nf_conntrack 133387 9 openvswitch,nf_nat,nf_nat_ipv4,nf_nat_ipv6,xt_conntrack,nf_nat_masquerade_ipv4,nf_conntrack_netlink,nf_conntrack_ipv4,nf_conntrack_ipv6 libcrc32c 12644 4 xfs,openvswitch,nf_nat,nf_conntrack
启动
[root@localhost openvswitch-2.8.1]# export PATH=$PATH:/usr/local/share/openvswitch/scripts [root@localhost openvswitch-2.8.1]# ovs-ctl start /usr/local/etc/openvswitch/conf.db does not exist ... (warning). Creating empty database /usr/local/etc/openvswitch/conf.db [ OK ] Starting ovsdb-server [ OK ] system ID not configured, please use --system-id ... failed! Configuring Open vSwitch system IDs [ OK ] Starting ovs-vswitchd [ OK ] Enabling remote OVSDB managers [ OK ]
启动ovsdb-server服务
[root@localhost openvswitch-2.8.1]# export PATH=$PATH:/usr/local/share/openvswitch/scripts [root@localhost openvswitch-2.8.1]# ovs-ctl --no-ovs-vswitchd start ovsdb-server is already running. Enabling remote OVSDB managers [ OK ]
启动ovs-vswitchd服务
[root@localhost openvswitch-2.8.1]# export PATH=$PATH:/usr/local/share/openvswitch/scripts [root@localhost openvswitch-2.8.1]# ovs-ctl --no--ovsdb-server start /usr/local/share/openvswitch/scripts/ovs-ctl: unknown option "--no--ovsdb-server" (use --help for help) ovsdb-server is already running. ovs-vswitchd is already running. Enabling remote OVSDB managers [ OK ]
配置ovsdb的数据库
[root@localhost openvswitch-2.8.1]# mkdir -p /usr/local/etc/openvswitch [root@localhost openvswitch-2.8.1]# ovs-ctl --no--ovsdb-server start /usr/local/share/openvswitch/scripts/ovs-ctl: unknown option "--no--ovsdb-server" (use --help for help) ovsdb-server is already running. ovs-vswitchd is already running. Enabling remote OVSDB managers [ OK ]
配置ovsdb-server以使用上面创建的数据库，监听Unix域套接字
[root@localhost openvswitch-2.8.1]# mkdir -p /usr/local/var/run/openvswitch [root@localhost openvswitch-2.8.1]# ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock > --remote=db:Open_vSwitch,Open_vSwitch,manager_options > --private-key=db:Open_vSwitch,SSL,private_key > --certificate=db:Open_vSwitch,SSL,certificate > --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert > --pidfile --detach --log-file 2019-12-30T12:30:01Z|00001|vlog|INFO|opened log file /usr/local/var/log/openvswitch/ovsdb-server.log ovsdb-server: /usr/local/var/run/openvswitch/ovsdb-server.pid: already running as pid 45678, aborting
使用ovs-vsctl初始化数据库
[root@localhost openvswitch-2.8.1]# ovs-vsctl --no-wait init [root@localhost openvswitch-2.8.1]# ovs-vswitchd --pidfile --detach --log-file 2019-12-30T12:31:39Z|00001|vlog|INFO|opened log file /usr/local/var/log/openvswitch/ovs-vswitchd.log ovs-vswitchd: /usr/local/var/run/openvswitch/ovs-vswitchd.pid: already running as pid 45688, aborting
接下来就可以使用了，使用ovs-vsctl show命令，查看ovs的版本号。
[root@localhost openvswitch-2.8.1]# ovs-vsctl show b9da3f20-b407-40fa-8944-df970f4ca3ad ovs_version: "2.8.1"
