Distributed file storage system fastdfs installation tutorial

Develop a habit, like first and then watch! ! ! !

1. Upload the compressed package to the opt directory

2. Unzip the file

cd /opt
tar -zxvf FastDFS_v5.05.tar.gz 

3. Compile the file

cd FastDFS
./make.sh

If the following error occurs, then we need to install this environment libfastcommon first

3.1 install libfastcommon

3.2 Upload files to the /usr/local directory and unzip

tar -zxvf libfastcommonV1.0.7.tar.gz

3.3 Enter the unzipped folder and start compiling

cd libfastcommon-1.0.7
./make.sh

If ./make.sh is not recognized, then run the following code

 yum -y install zlib zlib-devel pcre pcre-devel gcc gcc-c++ openssl openssl-devel libevent libevent-devel perl unzip net-tools wget

After that you can compile with the ./make.sh command

3.4 Compile and install

./make.sh install

Here we can see that he installed this thing in the /usr/lib64 directory by default, but the Fastdfs program will refer to the files in the /usr/lib directory by default, so we need to l ibfastcommon.so in the directory File assignment and paste to the /usr/lib directory

cp /usr/lib64/libfastcommon.so /usr/lib

4. Recompile and install our files

./make.sh
./make.sh install

So even if the compilation is successful.

Even if the installation is successful.

5. Copy all files in the conf configuration directory to /etc/fdfs

At this time, let’s check if there is such a directory. After checking, we found that there is none.

But when we choose to create the directory, we will find that the directory actually already exists.

mkdir /etc/fdfs

We can enter the directory to check, we can find that we can enter the directory,

cd fdfs

This means that when we installed Fastdfs, he already created it for us by default, and the knowledge directory is hidden

So we can directly copy all the files in the conf directory to the /etc/fdfs directory

cp * /etc/fdfs

6. Configure tracker.conf in the /etc/fdfs directory. This file is mainly to set the software data and log directory

We need to create a directory to store fastdfs data and logs

mkdir /opt/fastdfs
cd /etc/fdfs
vi tracker.conf

Modify this directory to the directory we just created to store data and logs

Then save and exit

7. Configure the storage.conf file, which is mainly the storage file

We mainly modify the following three places

This is the directory where our data and logs are stored

This place is where our files will be stored in the future. We can see that multiple file storage locations can be set here

Here is to modify the IP of the server where the tracker was deployed just now, because our tracker and storage are deployed on the same server, so we can directly use the local IP, because we are the Alibaba Cloud server , So we need to configure the firewall and open the security group rules later , otherwise the 22122 port will not be accessible

Configure firewall port number:

service firewalld start
firewall-cmd --zone=public --permanent --add-port=22122/tcp
firewall-cmd --reload
firewall-cmd --list-all 

Open a security group:

Remember that both the incoming and outgoing directions need to be configured

8. Configure the startup service of fdfs_storaged and fdfs_trackerd

Create /usr/local/fdfs first, then copy the two services in the installation directory to the /usr/local/fdfs directory

mkdir /usr/local/fdfs
cd /opt/FastDFS
cp stop.sh /usr/local/fdfs
cp restart.sh /usr/local/fdfs

After that, we can go to the /etc/init.d directory to modify the startup services of fdfs_storaged and fdfs_trackerd. Here, since we have installed the startup services of fdfs_storaged and fdfs_trackerd for us during the installation of fastdfs, we only need to modify them Can be configured

This is where the fdfs_trackerdfile needs to be modified

cd /etc/init.d
vi fdfs_trackerd

This is what fdfs_storagedneeds to be modified

cd /etc/init.d
vi fdfs_storaged

Add the service to the system service and start

chkconfig --add fdfs_storaged 
chkconfig --add fdfs_trackerd 
service fdfs_storaged start
service fdfs_trackerd start
ps -ef|grep fdfs

If you can see the following page, it means fdfs服务you have successfully started

9. Test file upload service

Fastdfs has a special directory for us to test. We can test whether our file service is really successful by modifying this directory.
First, modify the following configuration of the file etc/fdfs/client.conf:

vim /etc/fdfs/client.conf

Here we use the following command to upload pictures to test

/usr/bin/fdfs_test  /etc/fdfs/client.conf  upload test.jpg

/usr/bin/fdfs_test is a test demo that comes with
fastdfs /etc/fdfs/client.conf is the configuration of the test we just configured, the command will read the information of this configuration file
test.jpg represents the file name you want to upload , It is a file in the current directory,

but an error is reported here. At first glance, we know that port 23000 is not open, so we need to open this port. The steps are the same as the steps for opening port 22122 above. After opening the port, we re-tested and found that our file has been uploaded successfully,

and here he returned us a picture URL. But currently this URL is not accessible, because my server has not added Nginx for reverse proxy, this will be added later, but we can check whether the file exists by entering the corresponding directory. After checking, it was found that the file had indeed been stored. At this point, the installation of fastdfs has been basically completed.
