部署方案
安装步骤
步骤一:203、204、205、206、207、208安装FastDFS
参考:https://www.cnblogs.com/cac2020/p/9534967.html
步骤二:配置跟踪器(192.168.1.203 、192.168.1.204 节点)
mkdir -p /fastdfs/tracker&& cp /etc/fdfs/tracker.conf.sample tracker.conf && vim /etc/fdfs/tracker.conf 修改内容: base_path=/fastdfs/tracker #关键点:轮询分配到各个group里 store_lookup=0 启动: /etc/init.d/fdfs_trackerd start
步骤三:配置FastDFS存储(192.168.1.205-208)
205、206作为group1 , 207、208作为group2
mkdir -p /fastdfs/storage && cp /etc/fdfs/storage.conf.sample storage.conf && vim /etc/fdfs/storage.conf 修改内容: disabled=false group_name=group1 #组名,第一组(205、206)为 group1 第二组(207、208)为 group2 port=23000 #storage 端口号,同组的端口号必须相同 base_path=/fastdfs/storage store_path_count=1 #存储路径个数 需要和 store_path 个数匹配 store_path0=/fastdfs/storage #设置存储路径 tracker_server=192.168.1.203:22122 #tracker 服务器的 ip 和端口 tracker_server=192.168.1.204:22122 #多个 tracker 直接添加多条记录 http.server_port=8888 #设置 http 端口号 启动: /etc/init.d/fdfs_storaged start
到此为止我们的 FastDFS 集群环境已经搭建完成!!!!
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
步骤四:4个存储节点(205 206 207 208)整合Nginx
1.安装整合包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 修改内容:去掉第四行中的 local 文件层次 2.安装Nginx 加载fastdfs-nginx-module模块 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/ 重新编译命令: make && make install 3.修改整合模块配置 cp /usr/local/fast/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/ && vim /etc/fdfs/mod_fastdfs.conf 修改内容: 注意:第一组(205、206)和第二组(207、208) 节点修改内容,只有组名不同 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 #第一组为 group1 第二组为 group2 group_count = 2 #追加以下内容 [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.复制配置文件 cd /usr/local/fast/FastDFS/conf/ && cp http.conf mime.types /etc/fdfs/ 5.创建软连接,在/fastdfs/storage 文件存储目录下创建软连接,将其链接到实际存放数据的目录。 命令: ln -s /fastdfs/storage/data/ /fastdfs/storage/data/M00 6.修改 Nginx 配置文件4个节点 命令:vim usr/local/nginx.conf 修改内容: listen 8888; server_name localhost; location ~/group([0-9])/M00 { #alias /fastdfs/storage/data; ngx_fastdfs_module; } 启动4个节点Nginx: /usr/local/nginx/sbin/nginx
步骤五:在2个跟踪器节点上安装nginx为4个存储节点提供负载均衡
1.安装ngx_cache_purge-2.3.tar.gz(清除指定url的缓存) tar -zxvf /usr/local/software/ngx_cache_purge-2.3.tar.gz –C /usr/local/fast/ 2.安装Nginx 加入 ngx_cache_purge (加入清除缓存模块) 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/ 重新编译命令: make && make install 3.修改nginx配置 vim /usr/local/nginx/conf/nginx.conf 修改内容: events { worker_connections 1024; use epoll; } http { include mime.types; default_type application/octet-stream; sendfile on; tcp_nopush on; keepalive_timeout 65; #设置缓存 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; #设置缓存存储路径、存储方式、分配内存大小、磁盘最大空间、缓存期限 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 权重 max_fails 失败重试次数 fail_timeout 连接失败超时时间 #设置 group1 的服务器 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; } #设置 group2 的服务器 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; #设置 group 的负载均衡参数 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; } #设置清除缓存的访问权限 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,创建对应的缓存目录2个跟踪器节点都需要: mkdir -p /fastdfs/cache/nginx/proxy_cache mkdir -p /fastdfs/cache/nginx/proxy_cache/tmp 启动ngnix:/usr/local/nginx/sbin/nginx
步骤六:201、202节点安装keepalived+nginx,对203、204提供负载均衡并对外外提供统一访问IP
1.安装nginx 修改nginx配置 vim /usr/local/nginx/conf/nginx.conf 修改内容: 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 代理路径设置为 /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.安装keepalived 修改keepalived配置 参考:https://www.cnblogs.com/cac2020/p/9528106.html
最后注意:千万不要使用 kill -9 命令强杀 FastDFS 进程,否则可能会导致 binlog 数据丢失
关闭集群步骤: 1、201 202 两台一级负载节点 关闭 keepalived 命令:service keepalived stop 关闭 nginx 命令:/usr/local/nginx/sbin/nginx –s stop 2、203 204 两台二级负载节点,跟踪器节点 关闭 nginx 命令:/usr/local/nginx/sbin/nginx –s stop 关闭 trackerd 跟踪器命令:/etc/init.d/fdfs_trackerd stop 3、205 206 207 208 四台三级负载节点,存储节点 关闭 nginx 命令:/usr/local/nginx/sbin/nginx –s stop 关闭 storage 存储器命令: /etc/init.d/fdfs_storaged stop 注意:千万不要使用 kill -9 命令强杀 FastDFS 进程,否则可能会导致 binlog 数据丢失
