MooseFS 3.0部署筆記(4)【原創】

此文接 部署筆記3 ，介紹mfs高可用中的keepalived的部署.

keepAlived 安裝

1. 下載下傳 http://www.keepalived.org/software/keepalived-1.2.23.tar.gz

2. tar -xzvf keepalived-1.2.23.tar.gz

3. 下載下傳并安裝一下包，根據自己的作業系統版本定。

可用指令檢視相關元件的版本（rpm –qa| grep xxxx）。

rpm -ivh libcom_err-devel-1.41.12-11.el6.x86_64.rpm

rpm -ivh e2fsprogs-devel-1.41.12-11.el6.x86_64.rpm

rpm -ivh keyutils-libs-devel-1.4-3.el6.x86_64.rpm

rpm -ivh libsepol-devel-2.0.41-4.el6.x86_64.rpm

rpm -ivh libselinux-devel-2.0.94-5.2.el6.x86_64.rpm

rpm -ivh krb5-devel-1.9-22.el6.x86_64.rpm

rpm -ivh zlib-devel-1.2.3-27.el6.x86_64.rpm

rpm -ivh openssl-devel-1.0.0-20.el6.x86_64.rpm

4. 安裝keepalived

cd keepalived-1.2.23

./configure --prefix=/usr/local/keepalived

make & make install

5. 注冊服務

cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/

6. 配置

mkdir -p /etc/keepalived/

vi /etc/keepalived/keepalived.conf

chmod 755 /etc/keepalived/keepalived_drbd_mfs.sh

7. 啟動

sudo /etc/init.d/keepalived start

8. 關閉防火牆和selinux政策

vi /etc/sysconfig/selinux

修改：

SELINUX=disabled

#setenforce 0

9. 配置iptables，添加VRRP通訊支援, 允許多點傳播

iptables -A INPUT -d 224.0.0.18 -j ACCEPT

10. 驗證

能ping到 /etc/keepalived/keepalived.conf 中配置的虛位址，可以用 ip a 檢視虛位址綁定情況。

11. 修改keepalived 日志輸出。

預設keepalived 的日志輸出到 /var/log/messages ， 問題很不好查，以下修改日志輸出。

1） vi /etc/sysconfig/keepalived

修改最後一行 KEEPALIVED_OPTIONS="-D -d -S 0"

2） vi /etc/rsyslog.conf 添加

#keepalived -S 0

local0.* /var/log/keepalived.log

3） 重新開機日志服務

# /etc/init.d/rsyslog restart

4） 檢視日志

tail -1000 /var/log/keepalived.log

12. 抓包分析keepalived 通訊

tcpdump -i eth1 -n vrrp
