添加FRR用户和组
groupadd -r -g 92 frrgroupadd -r -g 85 frrvtyadduser --system --ingroup frr --home /var/run/frr/ --gecos "FRR suite" --shell /sbin/nologin frrusermod -a -G frrvty frr
编译阶段
git clone https://github.com/frrouting/frr.git frrcd frr./bootstrap.sh./configure --prefix=/usr --includedir=${prefix}/include --enable-exampledir=${prefix}/share/doc/frr/examples --bindir=${prefix}/bin --sbindir=${prefix}/lib/frr --libdir=${prefix}/lib/frr --libexecdir=${prefix}/lib/frr --localstatedir=/var/run/frr --sysconfdir=/etc/frr --with-moduledir=${prefix}/lib/frr/modules --with-libyang-pluginsdir=${prefix}/lib/frr/libyang_plugins --enable-configfile-mask=0640 --enable-logfile-mask=0640 --enable-snmp=agentx --enable-multipath=64 --enable-user=frr --enable-group=frr --enable-vty-group=frrvty --with-pkg-git-version --enable-systemd=yes --enable-doc-html --enable-ripd --enable-ripngd --enable-ldpd --enable-bgpdd --enable-eigrpd --enable-gcc-rdynamic --enable-watchfrr --enable-datacenter --enable-vtysh --enable-backtrace --enable-ospfapi --enable-ospfclient --enable-isisd --enable-snmp --enable-multipath=6 --enable-shell-access --disable-sysrepo --enable-fpmmakemake install
在make之前可能出现错误：libelf headers are required for building clippy
解决办法：apt-get install libelf-dev
安装FRR配置文件
install -m 775 -o frr -g frr -d /var/log/frrinstall -m 775 -o frr -g frrvty -d /etc/frrinstall -m 640 -o frr -g frrvty tools/etc/frr/vtysh.conf /etc/frr/vtysh.confinstall -m 640 -o frr -g frr tools/etc/frr/frr.conf /etc/frr/frr.confinstall -m 640 -o frr -g frr tools/etc/frr/daemons.conf /etc/frr/daemons.confinstall -m 640 -o frr -g frr tools/etc/frr/daemons /etc/frr/daemons
调整sysctl
1、vim /etc/sysctl.conf# Uncomment the next line to enable packet forwarding for IPv4net.ipv4.ip_forward=1# Uncomment the next line to enable packet forwarding for IPv6# Enabling this option disables Stateless Address Autoconfiguration# based on Router Advertisements for this hostnet.ipv6.conf.all.forwarding=12、sysctl -p
启用守护线程
vim /etc/frr/daemons将要使用的功能都改完yes
安装服务文件
install -m 644 tools/frr.service /etc/systemd/system/frr.servicesystemctl enable frrsystemctl start frr#查看服务状态service frr status
