Experiment Description:

1 mysql+3 is mogstored and tracker node + 1 Nginx Implementation of the reverse generation

To use fewer hosts, we use 2 hosts

Nginx + mogstored + Tracker

MySQL + mogstored + Tracker

The first step here is to quickly deploy mogstored + Tracker Environment (detailed deployment please refer to the previous blog)

1. First set up the MySQL server

MySQL > Grant all on mogdb.* to ' moguser ' @ ' 10.1.%.% ' identified by ' Mogpass ', MySQL > Grant all on *. * to ' root ' @ ' 10. 1.%.% ' identified by ' root '; -this permission is too large for the build environment to adjust MySQL > flush privileges as needed;

2.tracker + mogstored Configuration

Tracker configuration:

# mogdbsetup--dbhost=10.1.249.125--dbport=3306--dbname=mogdb >--dbrootuser=root--dbrootpass=root--dbuser= Moguser--dbpass=mogpass# vim/etc/mogilefs/mogilefsd.conf db_dsn = Dbi:mysql:mogdb:host=10.1.249.125db_user = Moguserdb_pass = Mogpasslisten = 0.0.0.0:7001# Service MOGILEFSD start# ss-tln | grep "7001"

3. Configure this server at the same time as the mogstored side

# mkdir-pv/var/mogdata/dev1# chown-r mogilefs.mogilefs/var/mogdata/# yum-y install perl-io-aio# service mogstored St art# NETSTAT-TLNP | grep "mogstored" # mogadm--trackers=10.1.249.125:7001 host add 10.1.249.125--ip=10.1.249.125--status=alive//if creation fails, May be due to the resolution of the/etc/hosts file and the true hostname inconsistency, modify the/etc/hosts file can be # scp/etc/mogilefs/* 10.1.252.53:/etc/mogilefs/to another server, Two servers using the same configuration file

4. Configure another server as a tracker+mogstored

At this point, the server as tracker, no need to initialize the database, the first one has been initialized # MKDIR/VAR/MOGDATA/DEV3-PV--The directory created here needs to be consistent with the name of the created device # Chown-r mogilefs.mogilefs/var/mogdata/# chown-r mogilefs.mogilefs/var/run/mogilefsd/# service MOGILEFSD start# Service mogstored start# mogadm--trackers=10.1.252.53:7001 host add 10.1.252.53--ip=10.1.252.53--status=alive

5. Add each other's host

# mogadm--trackers=10.1.252.53:7001 host add 10.1.249.125--ip=10.1.249.125--status=alive# mogadm--trackers= 10.1.249.125:7001 host add 10.1.252.53--ip=10.1.252.53--status=alive# mogadm--trackers=10.1.249.125:7001 Host list10.1.249.125 [1]: Alive ip:10.1.249.125:750010.1.252.53 [2]: Alive ip:10.1.252.53:7500 # Mogadm--tra CKERS=10.1.252.53:7001 host list10.1.249.125 [1]: Alive ip:10.1.249.125:750010.1.252.53 [2]: Alive ip:10.1 .252.53:7500

6. Add the device, in the same tracker operation can

# mogadm --trackers=10.1.249.125:7001 device add 10.1.249.125 1# mogadm  --trackers=10.1.249.125:7001 device add 10.1.252.53 3  -->  Consistent with the directories created above # mogadm --trackers=10.1.249.125:7001 device list10.1.249.125 [1]:  alive                     used (g)     free (g)    total (g)   weight (%)     dev1:   alive      6.484      84.630     91.114        10010.1.252.53  [2]: alive                     used (g)     free (g)    total (g)    weight (%)    DEV3:&Nbsp;  alive      6.176     84.938      91.114        100

7. Create a domain

# mogadm --trackers=10.1.249.125:7001 domain add images# mogadm --trackers= 10.1.249.125:7001 domain add files# mogadm --trackers=10.1.249.125:7001 domain  list domain                class                 Mindevcount   replpolicy   hashtype-------------------- ------------------- - ------------- ------------ ------- files                 default                    2         Multiplehosts ()  NONE    images                default                    2        multiplehosts ()  NONE

8. Create a class

# mogadm --trackers=10.1.252.53:7001 class add images class0 --mindevcount= 2# mogadm --trackers=10.1.252.53:7001 class add images class1 --mindevcount =2# mogadm --trackers=10.1.252.53:7001 class list domain                class                 mindevcount   replpolicy    hashtype-------------------- -------------------- ------------- ------------ - ------ files                 default                    2        multiplehosts ()  NONE     images               class0                     2         multiplehosts ()  NONE    images                class1                     2         multiplehosts ()  NONE    images                default                    2         multiplehosts ()  none

9.nginx Configuration

Compile and install Nginx to support the MogileFS module # tar xf nginx_mogilefs_module-1.0.4.tar.gz# tar xf  nginx-1.8.0.tar.gz# cd nginx-1.8.0# ./configure   --prefix=/usr    --sbin-path=/usr/sbin/nginx   --conf-path=/etc/nginx/nginx.conf   -- error-log-path=/var/log/nginx/error.log   --http-log-path=/var/log/nginx/access.log    --pid-path=/var/run/nginx/nginx.pid    --lock-path=/var/lock/nginx.lock    --user=nginx   --group=nginx   --with-http_ssl_module   -- With-http_flv_module   --with-http_stub_status_module   --with-http_gzip_static_ module   --http-client-body-temp-path=/var/tmp/nginx/client/   -- http-proxy-temp-path=/var/tmp/nginx/proxy/   --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/    --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi   --http-scgi-temp-path=/var/tmp/nginx/scgi   --with-pcre    --with-debug   --add-module= (Path to nginx_mogilefs_module-1.0.4 module) # make  && make install

Nginx Reverse mogilefs configuration file upstream mogilefscluster{server 10.1.252.53:7001; Server 10.1.249.125:7001;}    location/images/{Mogilefs_tracker mogilefscluster;    Mogilefs_domain images;        Mogilefs_pass {proxy_pass $mogilefs _path;        Proxy_hide_header Content-type;        Proxy_buffering off; }}

10. Back-end node upload a picture for testing (back-end two servers randomly select one can)

# mogupload--trackers=10.1.252.53:7001--domain=images--key= ' 1.jpg '--file= '/tmp/1.jpg ' # mogupload--trackers= 10.1.252.53:7001--domain=images--key= ' 2.jpg '--file= '/tmp/2.jpg ' # Moglistkeys--trackers=10.1.252.53:7001--domain =images1.jpg2.jpg

11. View the actual access path

# mogfileinfo-trackers=10.1.252.53:7001--domain=images--key= "1.jpg"-http://10.1.252.53:7500/dev3/0/000/000/ 0000000018.fid-http://10.1.249.125:7500/dev1/0/000/000/0000000018.fid--You can see there are two, because we have two mogstored, All mogilefs automatically helped us with redundancy.
