1.CentOS7FastDFS搭建

前面已下载好了要用到的工具集，下面就可以开始安装了：
如果安装过程中出现问题，可以下载我提供的，当前测试可以通过的工具包：

fastdfs-5.11下载
fastdfs-client-java-1.26下载
fastdfs-nginx-module-1.20下载
libfastcommon-1.36下载
nginx-1.12.0下载

请大家原谅我可耻的收了一分，写这么长的博文确实是很辛苦的，要花很长时间。如果觉得这篇博文帮忙到了你，还请帮忙下载支持一下。您的鼓励将成为我最大的动力。当然，作者的GitHub地址已提供给大家，大家可以去GitHub下载。

1.1 安装libfastcommon

由于我的centOS7是最小化安装，我里面没有安装zip解压。
先安装 ：

yum -y install unzip zip

安装成功后解压libfastcommon-master.zip

unzip libfastcommon-master.zip

进入我们刚刚解压的目录：

[root@localhost ftp]# cd libfastcommon-master
[root@localhost libfastcommon-master]# ll
total 32
drwxr-xr-x 2 root root  117 Apr  5 18:07 doc
-rw-r--r-- 1 root root 8005 Apr  5 18:07 HISTORY
-rw-r--r-- 1 root root  566 Apr  5 18:07 INSTALL
-rw-r--r-- 1 root root 1606 Apr  5 18:07 libfastcommon.spec
-rwxr-xr-x 1 root root 3099 Apr  5 18:07 make.sh
drwxr-xr-x 2 root root  191 Apr  5 18:07 php-fastcommon
-rw-r--r-- 1 root root 2763 Apr  5 18:07 README
drwxr-xr-x 3 root root 4096 Jun  8 21:51 src

当我们./make.sh的时候会提示，gcc命令没有找到。

用yum安装gcc:
yum命令相当好用，是RedHad和CentOS从指定服务器下载RPM包并自动安装。我个人比较喜欢。

yum -y install gcc-c++

这个时候分别执行./make.sh和./make.sh install，正常情况是可以成功的。
libfastcommon默认会被安装到/usr/lib64/libfastcommon.so但是FastDFS的主程序却在/usr/local/lib目录下
这个时候我们就要建立一个软链接了，实际上也相当于windows上的快捷方式。

ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so

1.2安装FastDFS

解压FastDFS安装包

unzip fastdfs-5.11.zip

解压后看到：

[root@localhost ftp]# ls
593d8f1eN5b3b8133.jpg            libfastcommon-master
fastdfs-5.11                     libfastcommon-master.zip
fastdfs-5.11.zip                 nginx-1.12.0.tar.gz
fastdfs-client-java-master.zip   record.txt
fastdfs-nginx-module-master.zip  zookeeper-3.4.6.tar.gz

进到刚解压的目录

cd fastdfs-5.11
./make.sh
./make.sh install

如果没有报错那么就成功了。安装log中会提示FastDFS安装到了/etc/fdfs目录下。

成功后查看安装目录：

[root@localhost ftp]# cd /etc/fdfs/
[root@localhost fdfs]# ll
-rw-r--r-- 1 root root  1461 Jun  8 21:56 client.conf.sample
-rw-r--r-- 1 root root  7927 Jun  8 21:56 storage.conf.sample
-rw-r--r-- 1 root root  7389 Jun  8 21:56 tracker.conf.sample

我们需要把这三个示例文件复制一份，去掉.sample。

cp client.conf.sample client.conf
cp storage.conf.sample storage.conf
cp tracker.conf.sample tracker.conf

FastDFS安装结束。

1.3安装tracker

1.3.1创建tracker工作目录

这个目录可以自定义，用来保存tracker的data和log
根据个人习惯，我创建了下面的目录：

[root@localhost ~]# cd /usr/
[root@localhost usr]# mkdir yong.cao
[root@localhost usr]# cd yong.cao/
[root@localhost yong.cao]# mkdir dev
[root@localhost yong.cao]# cd dev/
[root@localhost dev]# mkdir fastdfs
[root@localhost yong.cao]# cd fastdfs/
[root@localhost dev]# mkdir fastdfs_tracker
[root@localhost fastdfs]# cd fastdfs_tracker/
[root@localhost fastdfs_tracker]# pwd
/usr/yong.cao/dev/fastdfs/fastdfs_tracker        #这个是我最终创建的目录
[root@localhost fastdfs_tracker]#

1.3.2配置tracker

cd /etc/fdfs
vim tracker.conf

最小化的CentOS7是没有安装vim的，可以把vim tracker.conf命令改成vi tracker.conf，也可以去下载一个vim

yum -y install vim     #简单粗暴安装方法

打开后重点关注下面4个配置：
1.disabled=false #默认开启
2.port=22122 #默认端口号
3.base_path=/usr/yong.cao/dev/fastdfs/fastdfs_tracker #我刚刚创建的目录
4.http.server_port=6666 #默认端口是8080

1.3.3启动tracker

保存配置后启动tracker，命令如下：

service fdfs_trackerd start

如果不能启动，或提示用systemctl可改用命令：

systemctl start fdfs_trackerd

成功后应该可以看到：

[root@localhost fdfs]# service fdfs_trackerd start
Starting fdfs_trackerd (via systemctl):                    [  OK  ]

进行刚刚创建的tracker目录，发现目录中多了data和log两个目录

[root@localhost fdfs]# cd /usr/yong.cao/dev/fastdfs/fastdfs_tracker/
[root@localhost fastdfs_tracker]# ll
total 0
drwxr-xr-x 2 root root 178 Jun 16 21:19 data
drwxr-xr-x 2 root root  26 Jun 13 22:01 logs

最后我们需要给tracker加入开机启动

[root@localhost fastdfs_tracker]# ll /etc/rc.d/rc.local
-rw-r--r-- 1 root root 501 Jun 16 21:34 /etc/rc.d/rc.local

发现并没有执行权限，需要加一下：

chmod +x /etc/rc.d/rc.local

加完后应该是这样的：

-rwxr-xr-x 1 root root 501 Jun 16 21:34 /etc/rc.d/rc.local
修改rc.local
vim /etc/rc.d/rc.local

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
service fdfs_trackerd start

查看一下tracker的端口监听情况

[root@localhost fastdfs_tracker]# netstat -unltp|grep fdfs
tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      2231/fdfs_trackerd

端口22122成功监听。

1.4 安装storage

storage的安装与tracker很类似。

1.4.1 为storage配置工作目录

与tracker不现的是，由于storage还需要一个目录用来存储数据，所以我另外多建了一个fasdfs_storage_data
下面是我的目录结构：

[root@localhost fastdfs]# ls
fastdfs_storage  fastdfs_storage_data  fastdfs_tracker

1.4.2 修改storage配置文件

修改storage.conf

vim /etc/fdfs/storage.conf

1.disabled=false
2.group_name=group1 #组名，根据实际情况修改
3.port=23000 #设置storage的端口号，默认是23000，同一个组的storage端口号必须一致
4.base_path=/usr/yong.cao/dev/fastdfs/fastdfs_storage #设置storage数据文件和日志目录
5.store_path_count=1 #存储路径个数，需要和store_path个数匹配
6.base_path0=/usr/yong.cao/dev/fastdfs/fastdfs_storage_data #实际文件存储路径
7.tracker_server=192.168.128.131:22122 #我CentOS7的ip地址
8.http.server_port=8888 #设置 http 端口号

修改保存后创建软引用

ln -s /usr/bin/fdfs_storaged /usr/local/bin

1.4.3 启动storage

service fdfs_storaged start

如果不能启动，或提示用systemctl可改用命令：

systemctl start fdfs_storaged

成功后应该可以看到：

[root@localhost fdfs]# service fdfs_stroaged start
Starting fdfs_storaged (via systemctl):                    [  OK  ]

同样的，设置开机启动：
修改rc.local

vim /etc/rc.d/rc.local

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
service fdfs_trackerd start
service fdfs_storaged start

查看一下服务是否启动

[root@localhost fastdfs]# netstat -unltp | grep fdfs
tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      2231/fdfs_trackerd
tcp        0      0 0.0.0.0:23000           0.0.0.0:*               LISTEN      2323/fdfs_storaged

服务已正常启动。

1.4.4 校验整合

到这里，fastdfs的东西都已安装完成，最后我们还要确定一下，storage是否注册到了tracker中去。
查看命令：

/usr/bin/fdfs_monitor /etc/fdfs/storage.conf

成功后可以看到：
ip_addr = 192.168.128.131 (localhost.localdomain) ACTIVE
