linux下keepalived安裝教程
1、安裝環境
yum -y install kernel-devel*
yum -y install openssl-*
yum -y install popt-devel
yum -y install lrzsz
yum -y install openssh-clients
yum -y install libnl libnl-devel popt
2、開始安裝
上傳 keepalived-1.2.15.tar.gz 到伺服器 /usr/local/ 目錄下。
進入剛剛的目錄: cd /usr/local
解壓剛剛的檔案: tar -zxvf keepalived-1.2.15.tar.gz
進入解壓完的目錄:cd keepalived-1.2.15
可以看見下面有個configure檔案:
執行配置命令: ./configure --prefix=/usr/local/keepalived
編譯:make
安裝: make install
到這裡安裝就完成了
1.拷貝執行檔案 cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
2.將init.d檔案拷貝到etc下,加入開機啟動項 cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/keepalived
3.將keepalived檔案拷貝到etc下,加入網絡卡配置 cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
4.建立keepalived資料夾 mkdir -p /etc/keepalived
5.將keepalived配置檔案拷貝到etc下 cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf
6.新增可執行許可權 chmod +x /etc/init.d/keepalived
3、加入開機自啟
chkconfig --add keepalived #新增時必須保證/etc/init.d/keepalived存在
chkconfig keepalived on
新增完可查詢系統服務是否存在:chkconfig --list
可以看見 keepalived 已經存在了
4、啟動
啟動:service keepalived start
停止:service keepalived stop
重啟:service keepalived restart
4.1 配置日誌檔案
1.將keepalived日誌輸出到local0:
vi /etc/sysconfig/keepalived
KEEPALIVED_OPTIONS="-D -d -S 0"
2.在/etc/rsyslog.conf 末尾裡新增:
vim /etc/rsyslog.conf
local0.* /var/log/keepalived.log
3.重新啟動keepalived和rsyslog服務:
service rsyslog restart
service keepalived restart
5. 開啟防火牆的通訊地址
iptables -A INPUT -d 224.0.0.18 -j ACCEPT
/etc/rc.d/init.d/iptables save
