記錄下keepalived+haproxy 的啓動

 keepalived 啓動及指定日誌輸出

啓動haproxy

/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg

 

 

 

 

啓動keepalived

 配置文件必須是絕對路徑

/usr/local/keepalived/sbin/keepalived -D -f /usr/local/keepalived/etc/keepalived/keepalived.conf 

/usr/local/keepalived/sbin/keepalived -d -D -S 0 -f /usr/local/keepalived/etc/keepalived/keepalived.conf

 

 

 

 

首先查看keepalived命令的參數，-S指定syslog的facility。

 

1.  /usr/local/keepalived/sbin/keepalived --vrrp               -P    Only run with VRRP subsystem. 

2.  /usr/local/keepalived/sbin/keepalived --check              -C    Only run with Health-checker subsystem. 

3.  /usr/local/keepalived/sbin/keepalived --dont-release-vrrp  -V    Dont remove VRRP VIPs & VROUTEs on daemon stop. 

4.  /usr/local/keepalived/sbin/keepalived --dont-release-ipvs  -I    Dont remove IPVS topology on daemon stop. 

5.  /usr/local/keepalived/sbin/keepalived --dont-fork          -n    Dont fork the daemon process. 

6.  /usr/local/keepalived/sbin/keepalived --use-file           -f    Use the specified configuration file. 

7.                                Default is /etc/keepalived/keepalived.conf. 

8.  /usr/local/keepalived/sbin/keepalived --dump-conf          -d    Dump the configuration data. 

9.  /usr/local/keepalived/sbin/keepalived --log-console        -l    Log message to local console. 

10. /usr/local/keepalived/sbin/keepalived --log-detail         -D    Detailed log messages. 

11. /usr/local/keepalived/sbin/keepalived --log-facility       -S    0-7 Set syslog facility to LOG_LOCAL[0-7]. (default=LOG_DAEMON) 

12. /usr/local/keepalived/sbin/keepalived --help               -h    Display this short inlined help screen. 

13. /usr/local/keepalived/sbin/keepalived --version            -v    Display the version number 

14. /usr/local/keepalived/sbin/keepalived --pid                -p    pidfile 

15. /usr/local/keepalived/sbin/keepalived --checkers_pid       -c    checkers pidfile 

16. /usr/local/keepalived/sbin/keepalived --vrrp_pid           -r    vrrp pidfile 

而後經過以下命令啓動keepalived，

1.  [root@LVS02 ~]# /usr/local/keepalived/sbin/keepalived -d -D -S 0 

或者修改/etc/sysconfig/keepalived，而後用service來啓動。

1.  [root@LVS02 ~]# cat /etc/sysconfig/keepalived  

2.  # Options for keepalived. See `keepalived --help' output and keepalived(8) and 

3.  # keepalived.conf(5) man pages for a list of all options. Here are the most 

4.  # common ones : 

5.  # 

6.  # --vrrp               -P    Only run with VRRP subsystem. 

7.  # --check              -C    Only run with Health-checker subsystem. 

8.  # --dont-release-vrrp  -V    Dont remove VRRP VIPs & VROUTEs on daemon stop. 

9.  # --dont-release-ipvs  -I    Dont remove IPVS topology on daemon stop. 

10. # --dump-conf          -d    Dump the configuration data.

12. # --log-facility       -S    0-7 Set local syslog facility (default=LOG_DAEMON) 

13. # 

14.  

15. KEEPALIVED_OPTIONS="-D -d -S 0" 

16.  

17. [root@LVS02 ~]# service keepalived start

 指定日誌輸出

最後設置syslog，修改/etc/syslog.conf.

1.  root@LVS02 ~]# cat /etc/syslog.conf 

2.  # Log all kernel messages to the console. 

3.  # Logging much else clutters up the screen. 

4.  #kern.*                         /dev/console 

5.   

6.  # Log anything (except mail) of level info or higher. 

7.  # Don't log private authentication messages! 

8.  *.info;mail.none;authpriv.none;cron.none        /var/log/messages 

9.   

10. # The authpriv file has restricted access. 

11. authpriv.*                      /var/log/secure 

12.  

13. # Log all the mail messages in one place. 

14. mail.*                          -/var/log/maillog

18. cron.*                          /var/log/cron

20. # Everybody gets emergency messages 

21. *.emerg                         * 

22.  

23. # Save news errors of level crit and higher in a special file. 

24. uucp,news.crit                      /var/log/spooler 

25.  

26. # Save boot messages also to boot.log 

27. local7.*                        /var/log/boot.log 

28.  

29. # keepalived -S 0 

30. local0.*                                                /var/log/keepalived.log
