FastDFS file server implements dual-machine Hot Backup

FastDFS file server implements dual-machine Hot Backup

Two file fastDFS File Servers
Server A: 192.168.10.157
Server B: 192.168.10.158
The above implementation objective: to add a fastDFS Backup Server (192.168.10.158) as the slave server of the fastDFS File Server (192.168.10.157), two fastDFS file servers implement dual-machine hot backup.
That is, the data on the slave server (192.168.10.158) is always synchronized with the data on the master server (192.168.10.157) and changes with the data on the master server (192.168.10.157.
Environment Description
1. fastDFS Master server host name: Master
System: CentOS 6.6 IP: 192.168.10.157 FastDFS_v5.03. + nginx-1.6.2 + libevent-2.0.21-stable
2 fastDFS Slave server host name: Slave
System: CentOS 6.6 IP: 192.168.10.158 FastDFS_v5.03. + nginx-1.6.2 + libevent-2.0.21-stable
Note: We recommend that you use the same version of fastDFS and nginx as the master/slave server!
Start:
1. Install libevent
Note: perform the following operations on the two MySQL servers 192.168.10.157 and 192.168.21.158 respectively,
1. Download libevent-2.0.21-stable.tar.gz
Http://sourceforge.net/
2. decompress and install the configuration
Tar-zxvf libevent-2.0.21-stable.tar.gz
Cd libevent-2.0.21-stable
Mkdir-p/usr/local/libevnet
./Configure -- prefix =/usr/local/libevent
Make & make install
# Create a soft link to the/lib library for libevent. The 64-bit system corresponds to/lib64.
Ln-s/usr/local/libevent/lib/libevent-2.0.so.5/usr/lib/libevent-2.0.so.5

Ln-s/usr/local/libevent/lib/libevent-2.0.so.5/usr/lib64/libevent-2.0.so.5
At this point, the libevent installation is complete!
Ii. Install the fastDFS File Server
1、download lfastdfs_v5.03.tar.gz
Http://sourceforge.net/projects/fastdfs/
2. decompress and install the configuration
Tar zxvf FastDFS_v5.03.tar.gz
Cd FastDFS
Vim make. sh
# WITH_LINUX_SERVICE = 1/cancel comments of this row
./Make. sh
./Make. sh install
FastDFS installation is complete!

Files involving directories:/etc/fdfs/storage. conf/etc/fdfs/tracker. conf/etc/fdfs/client. conf/etc/fdfs/mod_fastdfs.conf
# Trackerd

/Usr/local/bin/restart. sh/usr/local/bin/fdfs_storaged/etc/fdfs/storage. conf
3. Create a storage path and configure fastDFS_v5.03

Mkdir-p/www/geebook_storage # create a storage directory
Mkdir-p/www/geebook_tracker # create a directory for the tracker Scheduler
Mkdir-p/www/geebook_client # create the client directory
Cp/etc/fdfs/storage. conf/etc/fdfs/storage. conf-bak # back up the configuration file
Cp/etc/fdfs/tracker. conf/etc/fdfs/tracker. conf-bak # back up the configuration file
Cp/etc/fdfs/client. conf/etc/fdfs/client. conf-bak # back up the configuration file
Vi/etc/fdfs/storage. conf # modify the parameters of the storage configuration file
Base_path =/www/geebook_stoarge # the base path to store data and log files
Store_path0 =/www/geebook_storage # store_path #, based 0, if store_path0 not exists, it's value is base_path
Tracker_server = 192.168.10.157 # You can specify multiple synchronized IP addresses for the tracker server address.
Tracker_server = 192.168.10.158
Vi/etc/fdfs/tracker. conf # modify the parameters of the tracker configuration file

 

Base_path =/www/geebook_tracker # the base path to store data and log files

Vi/etc/fdfs/client. conf # modify the parameters of the client configuration file
Base_path =/www/geebook_client # the base path to store log files
Tracker_server = 192.168.10.157 # You can specify multiple synchronized IP addresses for the tracker server address.
Tracker_server = 192.168.10.158

3. install and configure fastdfs-nginx-mod-install
1. Installation preparation #####
In cat/etc/fdfs/mod_fastdfs.conf, # include http. conf,
# Include http. conf in cat/etc/fdfs/client. conf, indicating comment # include http. conf
##### Add users and groups adduser -- system -- no-create-home -- disabled-password -- disabled-login -- group nginx
Groupadd nginx
Useradd-g nginx-s/bin/false-M nginx
2. Download the installation package and related dependent packages and create the installation directory.

8. test whether the dual-host hot backup of the fastDFS Master/Slave server is successful
1. Access the fastDFS Master/Slave server to start each service.
# Trackerd
/Usr/local/bin/stop. sh/usr/local/bin/fdfs_trackerd/etc/fdfs/tracker. conf
/Usr/local/bin/restart. sh/usr/local/bin/fdfs_trackerd/etc/fdfs/tracker. conf
