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 10.0.2.15:51098 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
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
