Installation and troubleshooting of radosgw under # Debian8

Software version information

Apache2.4.10

Ceph version 0.94.3-228-g2b11a4c (2b11a4c07a9416a2f75c8ce62a923994977d799c)

Debian 8.2 64 bit (kernel:Debian 3.16.7-ckt11-1+deb8u3 (2015-08-04) x86-64)

Please refer to the official documentation for the specific installation process.

Several key configuration files

Cat / etc/ceph/ ceph.confession [global].... [client.rgw.demo] host = demokeyring = / etc/ceph/ceph.client.radosgw.demo.keyringrgw socket path = / var/run/ceph/ceph-client.rgw.demo.asoklog file = / var/log/radosgw/client.radosgw.demo.logrgw print continue = falsecat / etc/apache2/sites-available/rgw.confServerName demoDocumentRoot / var/www/htmlErrorLog / var/log/apache2/rgw_error.logCustomLog / var/log/apache2/rgw_ Access.log combined# LogLevel debugRewriteEngine OnRewriteRule. *-[Eleven HTTP automatic HTTP:Authorization}% {HTTP} L] SetEnv proxy-nokeepalive 1ProxyPass / unix:///var/run/ceph/ceph-client.rgw.demo.asok | fcgi://localhost:9000/ # Note here corresponds to the path of the asok file in the previous ceph.conf

Note that the official document misses the operation of disabling the default site. You need to execute a2dissite 000-default. The test found a 500th error, as shown below.

To solve this problem, you need to open several key modules and restart the service, and there are still many official document pits.

A2enmod rewritea2enmod proxya2enmod proxy_fcgiservice apache2 restart

Note: the official document has made a major update to the configuration of apache2. The version before 2.4.9 directly uses fastcgi (mod_fastcgi), and after 2.4.10, it uses Unix Domain Socket (UDS) to factcgi (mod proxy_fcgi).
