radosgw 的civetweb 配置与排错

在64bit debian8 下面使用的仍然是sysinit，运行ceph-deploy rgw create 新建rgw的时候，提示rgw服务无法启动，排查如下：

检查ceph auth配置

	root@demo:/etc/ceph# ceph auth list
	......
	client.rgw.demo # 使用ceph-deploy rgw create的时候自动生成
		key: AQB0NPlVEkpPExAAaOAkz+X6fB9sJaMdR+Bq4Q==
		caps: [mon] allow rw
		caps: [osd] allow rwx

ceph auth已经生成了一个client.rgw.demo的用户，同时在/etc/ceph下面也生成了对于的keyring（没有，请手工添加）

	cat /etc/ceph/ceph.client.radosgw.demo.keyring
	[client.rgw.demo]
		key = AQB0NPlVEkpPExAAaOAkz+X6fB9sJaMdR+Bq4Q==

检查ceph.conf配置

	cat /etc/ceph/ceph.conf

	[client.rgw.demo] #重点是这个sections
	host = demo
	keyring = /etc/ceph/ceph.client.radosgw.demo.keyring
	rgw_frontends = civetweb port=80
	rgw socket path = /var/run/ceph/ceph-client.rgw.demo.asok #这个socket文件关联服务运行状态
	log file = /var/log/radosgw/client.radosgw.demo.log
	rgw print continue = false
	rgw enable ops log = false
	rgw ops log rados = false
	rgw ops log data bakclog = 4096

手工启动服务成功手工启动命令,注意-n为ceph auth里面的用户名

	手工启动
	radosgw  -n client.rgw.demo
	检查端口及进程
	netstat -talnp|grep rados
	tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      6601/radosgw
	tcp        0      0 10.0.2.15:58613         10.0.2.15:6789          ESTABLISHED 6601/radosgw
	tcp        0      0 10.0.2.15:55465         10.0.2.15:6800          ESTABLISHED 6601/radosgw
	tcp        0      0 10.0.2.15:51986         10.0.2.15:6804          ESTABLISHED 6601/radosgw
	tcp        0      0 10.0.2.15:51098         10.0.2.15:6808          ESTABLISHED 6601/radosgw

	ps aux|grep rados
	root      6601  0.5  1.5 2165088 15692 ?       Ssl  11:11   0:00 radosgw -n client.rgw.demo

init脚本启动与排错

	/etc/init.d/radosgw start
	/usr/bin/radosgw is not running.

启动失败，启动debug模式再来

	sh -x /etc/init.d/radosgw start
	+ PATH=/sbin:/bin:/usr/bin
	+ . /lib/lsb/init-functions
	+ run-parts --lsbsysinit --list /lib/lsb/init-functions.d
	+ [ -r /lib/lsb/init-functions.d/20-left-info-blocks ]
	+ . /lib/lsb/init-functions.d/20-left-info-blocks
	+ [ -r /lib/lsb/init-functions.d/40-systemd ]
	+ . /lib/lsb/init-functions.d/40-systemd
	+ _use_systemctl=0
	+ [ -d /run/systemd/system ]
	+ [ 0 = 1 ]
	+ FANCYTTY=
	+ [ -e /etc/lsb-base-logging.sh ]
	+ true
	+ VERBOSE=0
	+ [ start = -v ]
	+ [ start = --verbose ]
	+ PREFIX=client.radosgw.
	+ DEFAULT_USER=root
	+ which radosgw
	+ RADOSGW=/usr/bin/radosgw
	+ [ ! -x /usr/bin/radosgw ]
	+ ceph-conf --list-sections client.radosgw.
	+ daemon_is_running /usr/bin/radosgw
	+ daemon=/usr/bin/radosgw
	+ pidof /usr/bin/radosgw
	+ echo /usr/bin/radosgw is not running.
	/usr/bin/radosgw is not running.
	+ exit 1

重点就是ceph-conf --list-sections client.radosgw.,这里对ceph.conf配置文件的sections做了简单的检查，只认client.radosgw，而我们的ceph.conf里面写的是client.rgw，手工运行命令确认一下我们的判断

	ceph-conf --list-sections client.radosgw.
	无返回
	ceph-conf --list-sections client.rgw.
	client.rgw.demo

解决问题

方法1 修改启动脚本
方法2 修改ceph.conf的sections为client.radosgw.xxxx，同时ceph auth里面的用户也要改

我这里用方法1

	修改/etc/init.d/radosgw
	# prefix for radosgw instances in ceph.conf
	#PREFIX='client.radosgw.'
	PREFIX='client.rgw.'

	测试
	/etc/init.d/radosgw start
	Starting client.rgw.demo...
	/usr/bin/radosgw is running.

	ps -axu|grep radosgw
	root      7045  1.7  1.5 2165080 15696 ?       Ssl  11:30   0:00 /usr/bin/radosgw -n client.rgw.demo

	netstat -tuanlp|grep rados
	tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      7045/radosgw
	tcp        0      0 10.0.2.15:58617         10.0.2.15:6789          ESTABLISHED 7045/radosgw
	tcp        0      0 10.0.2.15:51990         10.0.2.15:6804          ESTABLISHED 7045/radosgw
	tcp        0      0 10.0.2.15:55469         10.0.2.15:6800          ESTABLISHED 7045/radosgw
	tcp        0      0 10.0.2.15:51102         10.0.2.15:6808          ESTABLISHED 7045/radosgw
