在《【FastDFS】小伙伴们说在CentOS 8服务器上搭建FastDFS环境总报错?》一文中,详细的介绍了如何在CentOS 8服务器搭建FastDFS环境。在生产环境中,往往需要对FastDFS实现高可用,进而实现文件的大规模分布式存储。那么,如何实现FastDFS的高可用呢?今天,我们就基于CentOS 8服务器来搭建FastDFS高可用集群环境。
我们在服务器的命令行输入如下命令来查看服务器的内核版本。
[root@localhost lib]# cat /etc/redhat-release
CentOS Linux release 8.1.1911 (Core)
可以看到,集群中每台服务器的内核版本为:release 8.1.1911 (Core)。
这里,我们总共规划了6台服务器,分别为:2台tracker服务器,4台storage服务器,其中2台storage服务器为group1,两台storage服务器为group2。具体如下所示。
tranker1:192.168.175.101
tracker2:192.168.175.102
storage1:192.168.175.103 group1
storage2:192.168.175.104 group1
storage3:192.168.175.105 group2
storage4:192.168.175.106 group2
在每台服务器上执行如下命令下载FastDFS。
[root@localhost source]# wget https://github.com/happyfish100/fastdfs/archive/V6.06.tar.gz
[root@localhost source]# wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.22.tar.gz
[root@localhost source]# wget https://github.com/happyfish100/libfastcommon/archive/V1.0.43.tar.gz
在每台服务器上执行如下命令安装FastDFS所依赖的环境。
[root@localhost dest]# yum install gcc gcc-c++
[root@localhost dest]# yum install libtool zlib zlib-devel openssl openssl-devel
[root@localhost dest]# yum -y install pcre pcre-devel libevent libevent-devel perl unzip net-tools wget
在每台服务器上依次执行如下命令。
(1)解压libfastcommon的压缩包
[root@localhost source]# tar -zxvf V1.0.43.tar.gz
(2)编译并安装编译并安装
[root@localhost source]# cd libfastcommon-1.0.43/
[root@localhost libfastcommon-1.0.43]# ./make.sh && ./make.sh install
(3)检查执行的结果,看安装是否成功
[root@localhost libfastcommon-1.0.43]# ls /usr/lib64|grep libfastcommon
libfastcommon.so
[root@localhost libfastcommon-1.0.43]# ls /usr/lib|grep libfastcommon
libfastcommon.so
在每台服务器上依次执行如下命令。
(1)解压fastdfs
[root@localhost source]# tar -zxvf V6.06.tar.gz
(2)安装fastdfs
[root@localhost source]# cd fastdfs-6.06/
[root@localhost fastdfs-6.06]# ./make.sh && ./make.sh install
(3)检查fastdfs是否安装成功
[root@localhost fastdfs-6.06]# ls /usr/bin|grep fdfs
fdfs_appender_test
fdfs_appender_test1
fdfs_append_file
fdfs_crc32
fdfs_delete_file
fdfs_download_file
fdfs_file_info
fdfs_monitor
fdfs_regenerate_filename
fdfs_storaged
fdfs_test
fdfs_test1
fdfs_trackerd
fdfs_upload_appender
fdfs_upload_file
在两台tracker服务器上,依次执行如下命令。
[root@localhost fastdfs-6.06]# cd /etc/fdfs/
[root@localhost fdfs]# cp client.conf.sample client.conf
[root@localhost fdfs]# cp tracker.conf.sample tracker.conf
注意:无须生成storage.conf文件,这两台tracker不做为storage。
在两台tracker服务器上,依次执行如下命令。
注意:tracker上不需要安装fastdfs-nginx-module
(1)解压Nginx
[root@localhost source]# tar -zxvf nginx-1.17.8.tar.gz
(2)nginx配置,http_stub_status_module 模块
[root@localhost fdfs]# cd /usr/local/source/nginx-1.17.8/
[root@localhost nginx-1.17.8]# ./configure --prefix=/usr/local/soft/nginx --with-http_stub_status_module
(3)编译安装Nginx
[root@localhost nginx-1.17.8]# make && make install
(4)检查安装是否成功
[root@localhost nginx-1.17.8]# ls /usr/local/soft/ | grep nginx
nginx
(5)查看指定的编译参数是否起作用
[root@localhost fdfs]# /usr/local/soft/nginx/sbin/nginx -V
nginx version: nginx/1.17.8
built by gcc 8.3.1 20190507 (Red Hat 8.3.1-4) (GCC)
configure arguments: --prefix=/usr/local/soft/nginx --with-http_stub_status_module
在两台tracker上,配置并启动FastDFS。
(1)创建tracker服务所需的目录
[root@localhost fdfs]# mkdir /data/fastdfs
[root@localhost fdfs]# mkdir /data/fastdfs/tracker
[root@localhost fdfs]# chmod 777 /data/fastdfs/tracker
(2)配置tracker服务,修改 tracker.conf 文件
[root@localhost fdfs]# vi /etc/fdfs/tracker.conf
只修改base_path一项的值为我们在上面所创建的目录即可
base_path = /data/fastdfs/tracker
(3)启动 tracker 服务
[root@localhost fdfs]# /etc/init.d/fdfs_trackerd start
(4)检查tracker服务启动是否成功
[root@localhost fdfs]# ps auxfww | grep fdfs
root 15067 0.0 0.0 12320 964 pts/0 S+ 15:14 0:00 | | \_ grep --color=auto fdfs
root 15026 0.0 0.1 90160 5940 ? Sl 15:13 0:00 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf
说明:能看到 fdfs_trackerd,表示tracker服务启动成功。
(5)检查tracker服务是否已绑定端口 22122
[root@localhost dest]# netstat -anp | grep 22122
tcp 0 0 0.0.0.0:22122 0.0.0.0:* LISTEN 15026/fdfs_trackerd
说明:22122端口是在/etc/fdfs/tracker.conf中定义的,如下所示:
# the tracker server port
port = 22122
两台tracker上,配置client.conf,配置fastdfs的客户端使用的配置文件。
(1)配置client.conf
[root@localhost fdfs]# vi /etc/fdfs/client.conf
以下两项配置用到的tracker目录和服务器地址端口
base_path = /data/fastdfs/tracker
tracker_server = 192.168.175.101:22122
tracker_server = 192.168.175.102:22122
说明:两台tracker上的client.conf配置相同
(2)从客户端的配置可以看到:客户端只需要了解tracker_server的信息。tracker server作用也正是负载均衡和调度
(3)Storage server作用是文件存储,客户端上传的文件最终存储在 Storage 服务上
用client.conf上传文件测试。
(1)从tacker上传一个文件
[root@0268c2dc2bf6 ~]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf /root/a.txt group1/M00/00/00/rBEABF5aTEeAXHF4AAAABHf4XZU792.txt
注意返回的是group1,我们可以group1下面的两台机器均找到此txt文件:
[root@d5d19e99e782 docker_tmp]# ls /data/fastdfs/storage/data/00/00
rBEABF5aTEeAXHF4AAAABHf4XZU792.txt
[root@f201111d0698 docker_tmp]# ls /data/fastdfs/storage/data/00/00
rBEABF5aTEeAXHF4AAAABHf4XZU792.txt
(2)指定group上传文件
如果想指定上传到某个group怎么办?例如:指定上传到group2
[root@0268c2dc2bf6 ~]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf /root/a.txt 192.168.175.105:23000
group2/M00/00/00/rBEABl5aUAqAXLCZAAAABHf4XZU043.txt
说明:指定group2中任一台的ip和端口即可。
(3)查看效果
[root@494ac47d63f8 fdfs]# ls /data/fastdfs/storage/data/00/00
rBEABl5aUAqAXLCZAAAABHf4XZU043.txt
[root@59fa1efff362 fdfs]# ls /data/fastdfs/storage/data/00/00
rBEABl5aUAqAXLCZAAAABHf4XZU043.txt
四台storage上:生成启动fastdfs默认的配置文件。
[root@localhost fastdfs-6.06]# cd /etc/fdfs/
[root@localhost fdfs]# cp storage.conf.sample storage.conf
[root@localhost fdfs]# cp client.conf.sample client.conf
说明:不需要生成tracker.conf,因为storage上不再运行tracker服务
四台storage上:安装nginx及fastdfs-nginx-module
(1)解压nginx
[root@localhost source]# tar -zxvf nginx-1.17.8.tar.gz
(2)解压fastdfs-nginx-module
[root@localhost source]# tar -zxvf V1.22.tar.gz
(3)修改config文件,把/usr/local 替换成 /usr
[root@localhost source]# cd fastdfs-nginx-module-1.22/
[root@localhost fastdfs-nginx-module-1.22]# cd src
[root@localhost src]# vi config
(4)Nginx配置,添加fastdfs-nginx-module和http_stub_status_module 模块
[root@localhost fdfs]# cd /usr/local/source/nginx-1.17.8/
[root@localhost nginx-1.17.8]# ./configure --prefix=/usr/local/soft/nginx --with-http_stub_status_module --add-module=/usr/local/source/fastdfs-nginx-module-1.22/src/
(5)编译安装nginx
[root@localhost nginx-1.17.8]# make && make install
(6)检查安装是否成功
[root@localhost nginx-1.17.8]# ls /usr/local/soft/ | grep nginx
nginx
(7)查看指定的编译参数是否起作用
[root@localhost fdfs]# /usr/local/soft/nginx/sbin/nginx -V
nginx version: nginx/1.17.8
built by gcc 8.3.1 20190507 (Red Hat 8.3.1-4) (GCC)
configure arguments: --prefix=/usr/local/soft/nginx --with-http_stub_status_module --add-module=/usr/local/source/fastdfs-nginx-module-1.22/src/
四台storage上:配置并启动storage服务
(1)创建storage服务所需的目录
[root@localhost fdfs]# mkdir /data/fastdfs/storage
[root@localhost fdfs]# chmod 777 /data/fastdfs/storage/
(2)配置storage服务
编辑storage的配置文件:
[root@localhost fdfs]# vi /etc/fdfs/storage.conf
各配置项包括:
group_name = group1
#配置base_path为上面所创建的storage目录
base_path = /data/fastdfs/storage
#store_path :存储所在的目录,可以设置多个,注意从0开始
store_path0 = /data/fastdfs/storage
#tracker_server的ip和端口
tracker_server = 192.168.175.101:22122
tracker_server = 192.168.175.102:22122
#指定http服务的端口
http.server_port = 80
配置的不同之处:
192.168.175.103 group_name = group1
192.168.175.104 group_name = group1
192.168.175.105 group_name = group2
192.168.175.106 group_name = group2
(3)启动storage服务
[root@localhost fdfs]# /etc/init.d/fdfs_storaged start
正在启动 fdfs_storaged (via systemctl): [ 确定 ]
(4)检查storage服务启动是否成功
[root@localhost fdfs]# ps auxfww | grep fdfs
root 15630 0.0 0.0 12320 972 pts/0 S+ 15:46 0:00 | | \_ grep --color=auto fdfs
root 15026 0.0 0.1 155696 6964 ? Sl 15:13 0:00 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf
root 15573 2.7 1.7 150736 66292 ? Sl 15:45 0:02 /usr/bin/fdfs_storaged /etc/fdfs/storage.conf
说明:看到fdfs_storaged,表示storage服务启动成功
(5)检查storage服务是否已绑定到端口:23000
[root@localhost fdfs]# netstat -anp | grep 23000
tcp 0 0 0.0.0.0:23000 0.0.0.0:* LISTEN 15573/fdfs_storaged
说明:23000 端口是在配置文件 /etc/fdfs/storage.conf中定义的,如下:
# the storage server port
port = 23000
四台存储服务器上:配置fastdfs-nginx-module
(1)生成配置文件
[root@localhost nginx-1.17.8]# cp /usr/local/source/fastdfs-nginx-module-1.22/src/mod_fastdfs.conf /etc/fdfs/
(2)编辑配置文件
[root@localhost nginx-1.17.8]# vi /etc/fdfs/mod_fastdfs.conf
配置以下几项
group_name=group1
connect_timeout=10
tracker_server=192.168.175.101:22122
tracker_server=192.168.175.102:22122
url_have_group_name = true
store_path0=/data/fastdfs/storage
group_count = 2
[group1]
group_name=group1
storage_server_port=23000
store_path_count=1
store_path0=/data/fastdfs/storage
[group2]
group_name=group2
storage_server_port=23000
store_path_count=1
store_path0=/data/fastdfs/storage
说明:最上面的group_name:当机器属于group1这组时,值为group1;当机器属于group2这组时,值为group2。
说明:url_have_group_name = true。注意:这一项不要漏掉,会导致nginx不正常工作
(3)复制另两个web访问用到配置文件到fdfs配置目录下:
[root@d5d19e99e782 /]# cp /usr/local/source/fastdfs-6.06/conf/http.conf /etc/fdfs/
[root@d5d19e99e782 /]# cp /usr/local/source/fastdfs-6.06/conf/mime.types /etc/fdfs/
四台存储服务器上:配置nginx
编辑nginx的配置文件:
[root@localhost conf]# vi /usr/local/soft/nginx/conf/nginx.conf
在server listen 80 的这个server配置下面,
增加一个location
location ~/group([0-9]) {
root /data/fastdfs/storage/data;
ngx_fastdfs_module;
}
(1)启动Nginx
[root@localhost storage]# /usr/local/soft/nginx/sbin/nginx
(2)检查nginx是否已成功启动
[root@localhost storage]# ps auxfww | grep nginx
root 24590 0.0 0.0 12320 980 pts/0 S+ 16:44 0:00 | | \_ grep --color=auto nginx
root 24568 0.0 0.0 41044 428 ? Ss 16:44 0:00 \_ nginx: master process /usr/local/soft/nginx/sbin/nginx
nobody 24569 0.0 0.1 74516 4940 ? S 16:44 0:00 \_ nginx: worker process
说明:这一步等待四台storage server配置完成后再进行。使用n=Nginx做upstream负载均衡的原因:可以通过一个地址访问后端的多个group
(1)文件上传完成后,从浏览器访问各个storage的Nginx即可:
例如:
http://192.168.175.103/group1/M00/00/00/rBEABF5aTRiAEuHwAAAABHf4XZU322.txt
http://192.168.175.104/group1/M00/00/00/rBEABF5aTRiAEuHwAAAABHf4XZU322.txt
http://192.168.175.105/group2/M00/00/00/rBEABl5aUAqAXLCZAAAABHf4XZU043.txt
http://192.168.175.106/group2/M00/00/00/rBEABl5aUAqAXLCZAAAABHf4XZU043.txt
说明:各台storage server的ip地址后面跟着上传时所返回的地址。注意:只能访问各台机器所在的group,
(2)配置nginx.conf
[root@0268c2dc2bf6 ~]# vi /usr/local/soft/nginx/conf/nginx.conf
内容:
添加 upstream到后端的storage。
upstream fdfs_group1 {
server 192.168.175.103:80 weight=1 max_fails=2 fail_timeout=30s;
server 192.168.175.104:80 weight=1 max_fails=2 fail_timeout=30s;
}
upstream fdfs_group2 {
server 192.168.175.105:80 weight=1 max_fails=2 fail_timeout=30s;
server 192.168.175.106:80 weight=1 max_fails=2 fail_timeout=30s;
}
针对带有group的url进行处理
location /group1 {
proxy_next_upstream http_502 http_504 error timeout invalid_header;
proxy_pass http://fdfs_group1;
expires 30d;
}
location /group2 {
proxy_next_upstream http_502 http_504 error timeout invalid_header;
proxy_pass http://fdfs_group2;
expires 30d;
}
(3)重启测试
[root@0268c2dc2bf6 ~]# /usr/local/soft/nginx/sbin/nginx -s stop
[root@0268c2dc2bf6 ~]# /usr/local/soft/nginx/sbin/nginx
在浏览器中访问:
http://192.168.175.101/group1/M00/00/00/rBEABF5aTRiAEuHwAAAABHf4XZU322.txt
http://192.168.175.101/group2/M00/00/00/rBEABl5aUAqAXLCZAAAABHf4XZU043.txt
