Ubuntu下部署Keepalived

Ubuntu下部署Keepalived
 Keepalived是一種防止單點故障的高可用解決方案。 首先下載: cd /usrwget http://www.keepalived.org/software/keepalived-1.2.7.tar.gz 解壓：  www.2cto.com   tar zxvf keepalived-1.2.7.tar.gz編譯之前需要安裝幾個程式庫 [plain] apt-get install libssl-dev  apt-get install openssl  apt-get install libpopt-dev   然後運行[plain] ./configure --prefix=/usr  得到如下結果： [plain] Keepalived configuration  ------------------------  Keepalived version       : 1.2.7  Compiler                 : gcc  Compiler flags           : -g -O2  Extra Lib                : -lpopt -lssl -lcrypto   Use IPVS Framework       : Yes  IPVS sync daemon support : Yes  IPVS use libnl           : No  Use VRRP Framework       : Yes  Use VRRP VMAC            : Yes  SNMP support             : No  Use Debug flags          : No  編譯吧：makemake install 程式安裝到下面幾個目錄： /usr/sbin中包含可執行程式keepalived  www.2cto.com  /usr/etc/keepalived/ 中包含了設定檔和例子/usr/etc/rc.d/init.d/keepalived 是可以作為service的指令檔,複製到/etc/init.d目錄下 修改三處： [plain] #. /etc/rc.d/init.d/functions  . /lib/lsb/init-functions  [plain] #. /etc/sysconfig/keepalived  . /usr/etc/sysconfig/keepalived  因為redhat之外的Linux沒有上面兩處目錄。  www.2cto.com   下面也要修改，將${..} 直接用start替換。[plain] start() {      echo -n $"Starting $prog: "      #daemon keepalived ${KEEPALIVED_OPTIONS}      daemon keepalived start      RETVAL=$?      echo      [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog  }  還要建立目錄[plain] mkdir -p /var/lock/subsys   現在設定為系統服務[plain] update-rc.d keepalived default   安裝daemon服務。apt-get install daemon 好了，終於可以正常啟動了。service keepalived start關閉用service keepalived stop
