在64bit debian8 下面使用的仍然是sysinit，運行ceph-deploy rgw create 新建rgw的時候，提示rgw服務沒法啓動，排查以下：web

檢查ceph auth配置frontend

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

ceph auth已經生成了一個client.rgw.demo的用戶，同時在/etc/ceph下面也生成了對於的keyring（沒有，請手工添加）socket

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

檢查ceph.conf配置tcp

cat /etc/ceph/ceph.conf

	[client.rgw.demo] #重點是這個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 #這個socket文件關聯服務運行狀態
	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

手工啓動服務成功手工啓動命令,注意-n爲ceph auth裏面的用戶名測試

手工啓動
	radosgw  -n client.rgw.demo
	檢查端口及進程
	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腳本啓動與排錯debug

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

啓動失敗，啓動debug模式再來code

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

重點就是ceph-conf --list-sections client.radosgw.,這裏對ceph.conf配置文件的sections作了簡單的檢查，只認client.radosgw，而咱們的ceph.conf裏面寫的是client.rgw，手工運行命令確認一下咱們的判斷進程

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

解決問題ci

方法1 修改啓動腳本
方法2 修改ceph.conf的sections爲client.radosgw.xxxx，同時ceph auth裏面的用戶也要改

我這裏用方法1it

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

	測試
	/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
