安裝步驟
步驟一:203、204、205、206、207、208安裝FastDFS
參考:https://www.cnblogs.com/cac2020/p/9534967.html
步驟二:配置跟蹤器(192.168.1.203 、192.168.1.204 節點)
mkdir -p /fastdfs/tracker&& cp /etc/fdfs/tracker.conf.sample tracker.conf && vim /etc/fdfs/tracker.conf 修改內容: base_path=/fastdfs/tracker #關鍵點:輪詢分配到各個group里 store_lookup=0 啟動: /etc/init.d/fdfs_trackerd start
步驟三:配置FastDFS存儲(192.168.1.205-208)
205、206作為group1 , 207、208作為group2
mkdir -p /fastdfs/storage && cp /etc/fdfs/storage.conf.sample storage.conf && vim /etc/fdfs/storage.conf 修改內容: disabled=false group_name=group1 #組名,第一組(205、206)為 group1 第二組(207、208)為 group2 port=23000 #storage 端口號,同組的端口號必須相同 base_path=/fastdfs/storage store_path_count=1 #存儲路徑個數 需要和 store_path 個數匹配 store_path0=/fastdfs/storage #設置存儲路徑 tracker_server=192.168.1.203:22122 #tracker 服務器的 ip 和端口 tracker_server=192.168.1.204:22122 #多個 tracker 直接添加多條記錄 http.server_port=8888 #設置 http 端口號 啟動: /etc/init.d/fdfs_storaged start
到此為止我們的 FastDFS 集群環境已經搭建完成!!!!
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
步驟四:4個存儲節點(205 206 207 208)整合Nginx
1.安裝整合包fastdfs-nginx-module_v1.16.tar.gz tar -zxvf /usr/local/software/fastdfs-nginx-module_v1.16.tar.gz -C /usr/local/fast/ vim /usr/local/fast/fastdfs-nginx-module/src/config 修改內容:去掉第四行中的 local 文件層次 2.安裝Nginx 加載fastdfs-nginx-module模塊 tar -zxvf /usr/local/software/nginx-1.6.2.tar.gz -C /usr/local cd /usr/local/nginx-1.6.2 && ./configure --add-module=/usr/local/fast/fastdfs-nginx-module/src/ 重新編譯命令: make && make install 3.修改整合模塊配置 cp /usr/local/fast/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/ && vim /etc/fdfs/mod_fastdfs.conf 修改內容: 注意:第一組(205、206)和第二組(207、208) 節點修改內容,只有組名不同 connect_timeout=10 tracker_server=192.168.1.203:22122 tracker_server=192.168.1.204:22122 storage_server_port=23000 url_have_group_name = true store_path0=/fastdfs/storage group_name=group1 #第一組為 group1 第二組為 group2 group_count = 2 #追加以下內容 [group1] group_name=group1 storage_server_port=23000 store_path_count=1 store_path0=/fastdfs/storage [group2] group_name=group2 storage_server_port=23000 store_path_count=1 store_path0=/fastdfs/storage 4.復制配置文件 cd /usr/local/fast/FastDFS/conf/ && cp http.conf mime.types /etc/fdfs/ 5.創建軟連接,在/fastdfs/storage 文件存儲目錄下創建軟連接,將其鏈接到實際存放數據的目錄。 命令: ln -s /fastdfs/storage/data/ /fastdfs/storage/data/M00 6.修改 Nginx 配置文件4個節點 命令:vim usr/local/nginx.conf 修改內容: listen 8888; server_name localhost; location ~/group([0-9])/M00 { #alias /fastdfs/storage/data; ngx_fastdfs_module; } 啟動4個節點Nginx: /usr/local/nginx/sbin/nginx
步驟五:在2個跟蹤器節點上安裝nginx為4個存儲節點提供負載均衡
1.安裝ngx_cache_purge-2.3.tar.gz(清除指定url的緩存) tar -zxvf /usr/local/software/ngx_cache_purge-2.3.tar.gz –C /usr/local/fast/ 2.安裝Nginx 加入 ngx_cache_purge (加入清除緩存模塊) tar -zxvf /usr/local/software/nginx-1.6.2.tar.gz -C /usr/local cd /usr/local/nginx-1.6.2 && ./configure --add-module=/usr/local/fast/ngx_cache_purge-2.3/src/ 重新編譯命令: make && make install 3.修改nginx配置 vim /usr/local/nginx/conf/nginx.conf 修改內容: events { worker_connections 1024; use epoll; } http { include mime.types; default_type application/octet-stream; sendfile on; tcp_nopush on; keepalive_timeout 65; #設置緩存 server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 300m; proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header Cookie $http_cookie; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 90; proxy_read_timeout 90; proxy_send_timeout 90; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; #設置緩存存儲路徑、存儲方式、分配內存大小、磁盤最大空間、緩存期限 proxy_cache_path /fastdfs/cache/nginx/proxy_cache levels=1:2 keys_zone=http-chche:200m max_size=1g inactive=30d; proxy_temp_path /fastdfs/cache/nginx/proxy_cache/tmp; # weight 權重 max_fails 失敗重試次數 fail_timeout 連接失敗超時時間 #設置 group1 的服務器 upstream fdfs_group1 { server 192.168.1.205:8888 weight=1 max_fails=2 fail_timeout=30s; server 192.168.1.206:8888 weight=1 max_fails=2 fail_timeout=30s; } #設置 group2 的服務器 upstream fdfs_group2 { server 192.168.1.207:8888 weight=1 max_fails=2 fail_timeout=30s; server 192.168.1.208:8888 weight=1 max_fails=2 fail_timeout=30s; } server { listen 8000; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; #設置 group 的負載均衡參數 location /group1/M00 { proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_cache http-cache; proxy_cache_valid 200 304 12h; proxy_cache_key $uri$is_args$args; proxy_pass http://fdfs_group1; expires 30d; } location /group2/M00 { proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_cache http-cache; proxy_cache_valid 200 304 12h; proxy_cache_key $uri$is_args$args; proxy_pass http://fdfs_group2; expires 30d; } #設置清除緩存的訪問權限 location ~/purge(/.*) { allow 127.0.0.1; allow 192.168.1.0/24; deny all; proxy_cache_purge http-cache $1$is_args$args; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } 4.按以上nginx 配置文件的要求,創建對應的緩存目錄2個跟蹤器節點都需要: mkdir -p /fastdfs/cache/nginx/proxy_cache mkdir -p /fastdfs/cache/nginx/proxy_cache/tmp 啟動ngnix:/usr/local/nginx/sbin/nginx
步驟六:201、202節點安裝keepalived+nginx,對203、204提供負載均衡並對外外提供統一訪問IP
1.安裝nginx 修改nginx配置 vim /usr/local/nginx/conf/nginx.conf 修改內容: upstream fastdfs_tracker { server 192.168.1.203:8000 weight=1 max_fails=2 fail_timeout=30s; server 192.168.1.204:8000 weight=1 max_fails=2 fail_timeout=30s; } server { listen 80; server_name localhost; location / { root html; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } ## FastDFS Proxy 代理路徑設置為 /fastdfs location /fastdfs { root html; index index.html index.htm; proxy_pass http://fastdfs_tracker/; proxy_set_header Host $http_host; proxy_set_header Cookie $http_cookie; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; client_max_body_size 300m; } } 2.安裝keepalived 修改keepalived配置 參考:https://www.cnblogs.com/cac2020/p/9528106.html
最后注意:千萬不要使用 kill -9 命令強殺 FastDFS 進程,否則可能會導致 binlog 數據丟失
關閉集群步驟: 1、201 202 兩台一級負載節點 關閉 keepalived 命令:service keepalived stop 關閉 nginx 命令:/usr/local/nginx/sbin/nginx –s stop 2、203 204 兩台二級負載節點,跟蹤器節點 關閉 nginx 命令:/usr/local/nginx/sbin/nginx –s stop 關閉 trackerd 跟蹤器命令:/etc/init.d/fdfs_trackerd stop 3、205 206 207 208 四台三級負載節點,存儲節點 關閉 nginx 命令:/usr/local/nginx/sbin/nginx –s stop 關閉 storage 存儲器命令: /etc/init.d/fdfs_storaged stop 注意:千萬不要使用 kill -9 命令強殺 FastDFS 進程,否則可能會導致 binlog 數據丟失
