  • FastDFS安装配置


    本地虚拟机搭建了一下FastDFS的环境,总结一番,其中很多不足还望大家指正。

    俩VM虚拟机
    10.240.37.87
    10.240.37.90

    既是tracker也是storage

    tracker 8081 #http端口
    storage 8080 #http端口


    一.VM设置网桥模式,共用实际的物理网卡

    1.VM网卡配置 cat /etc/sysconfig/network-scripts/ifcfg-eth0

    (1)10.240.37.87的网卡配置

    DEVICE=eth0
    HWADDR=00:0C:29:CA:8F:65
    NETMASK=255.255.255.0
    IPADDR=10.240.37.87
    GATEWAY=10.240.37.1
    TYPE=Ethernet
    UUID=3481be4a-0c13-4de2-ac7a-15136740f9e0
    ONBOOT=yes
    NM_CONTROLLED=yes
    BOOTPROTO=none
    PEERDNS=yes

    (2)10.240.37.90的网卡配置

    DEVICE=eth0
    HWADDR=00:0C:29:CA:8F:65
    NETMASK=255.255.255.0
    IPADDR=10.240.37.87
    GATEWAY=10.240.37.1
    TYPE=Ethernet
    UUID=3481be4a-0c13-4de2-ac7a-15136740f9e0
    ONBOOT=yes
    NM_CONTROLLED=yes
    BOOTPROTO=none
    PEERDNS=yes


    (3)DNS服务器
    more /etc/resolv.conf

    nameserver 192.168.100.10
    nameserver 192.168.100.11

    二、安装

    ./configure --prefix = /usr/local/zlib
    make
    make install

    (3).安装openssl

    cd /usr/local/
    wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
    tar -zxvf openssl-1.0.1c.tar.gz
    ./config --prefix = /usr/local/openssl
    make
    make install

    (4).下载编译LuaJIT
    wget -c http://luajit.org/download/LuaJIT-2.0.2.tar.gz

    echo "/usr/local/luajit/lib" > /etc/ld.so.conf.d/usr_local_luajit_lib.conf
    ldconfig
    #注意环境变量!
    export LUAJIT_LIB=/usr/local/luajit/lib
    export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0

    (5).解压如下软件
    tar xzvf lua-nginx-module-0.9.15.tar.gz
    tar xzvf echo-nginx-module.tar.gz
    tar zxvf simpl-ngx_devel_kit.tar.gz
    tar zxvf ngx_cache_purge-2.3.tar.gz
    tar zxvf fastdfs-nginx-module_v1.15.tar.gz


    7.编译安装nginx
    tar -zxvf nginx-1.8.0.tar.gz
    cd ginx-1.8.0
    ./configure --with-http_gzip_static_module --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --prefix=/usr/local/nginx --with-

    add-module=/usr/local/lua-nginx-module-0.9.15 --add-module=/usr/local/openresty-echo-nginx-module-7bc71d2 --add-module=/usr/local/ngx_cache_purge-2.3 --add-
    module=/usr/local/fastdfs-nginx-module/src


    三、配置

    1.配置tracker
    vim /etc/fdfs/tracker.conf

    10.240.37.87的tracker如下:
    disabled=false #启用配置文件
    port=22122 #设置tracker的端口号
    base_path=/data1/tracker #设置tracker的数据文件和日志目录(需预先创建)
    http.server_port=8081 #设置http端口号
    如需要进行性能调优,可以参照附录的配置文件的详细说明。

    10.240.37.90的tracker如下:
    disabled=false #启用配置文件
    port=22122 #设置tracker的端口号
    base_path=/data2/tracker #设置tracker的数据文件和日志目录(需预先创建)
    http.server_port=8081 #设置http端口号
    如需要进行性能调优,可以参照附录的配置文件的详细说明。


    2.配置storage
    vim /etc/fdfs/storage.conf

    10.240.37.87的storage如下:

    disabled=false #启用配置文件
    group_name=G1 #组名,根据实际情况修改
    port=23000 #设置storage的端口号
    base_path=/data1/storage #设置storage的日志目录(需预先创建)
    store_path_count=1 #存储路径个数,需要和store_path个数匹配
    store_path0=/data1/storage #存储路径
    tracker_server=10.240.37.87:22122 #tracker服务器的IP地址和端口号
    tracker_server=10.240.37.90:22122 #tracker服务器的IP地址和端口号
    http.server_port=8080 #设置http端口号

    10.240.37.90的storage如下:

    disabled=false #启用配置文件
    group_name=G2 #组名,根据实际情况修改
    port=23000 #设置storage的端口号
    base_path=/data2/storage #设置storage的日志目录(需预先创建)
    store_path_count=1 #存储路径个数,需要和store_path个数匹配
    store_path0=/data2/storage #存储路径
    tracker_server=10.240.37.87:22122 #tracker服务器的IP地址和端口号
    tracker_server=10.240.37.90:22122 #tracker服务器的IP地址和端口号
    http.server_port=8080 #设置http端口号

    3.配置mod_fastdfs.conf

    cp /usr/local/fastdfs-nginx-module/src/mod_fastdfs.conf  /etc/fdfs/

    vim /etc/fdfs/mod_fastdfs.conf

    10.240.37.87的mod_fastdfs.conf配置如下:
    base_path=/data1/storage #保存日志目录
    tracker_server=10.240.37.87:22122 #tracker服务器的IP地址以及端口号
    tracker_server=10.240.37.90:22122
    storage_server_port=23000 #storage服务器的端口号
    group_name=G1 #当前服务器的group名
    url_have_group_name = true #文件url中是否有group名
    store_path_count=1 #存储路径个数,需要和store_path个数匹配
    store_path0=/data1/storage #存储路径
    http.need_find_content_type=true #从文件扩展名查找文件类型(nginx时为true)
    #include http.conf #开启http服务


    10.240.37.90的mod_fastdfs.conf配置如下:
    base_path=/data2/storage #保存日志目录
    tracker_server=10.240.37.87:22122 #tracker服务器的IP地址以及端口号
    tracker_server=10.240.37.90:22122
    storage_server_port=23000 #storage服务器的端口号
    group_name=G2 #当前服务器的group名
    url_have_group_name = true #文件url中是否有group名
    store_path_count=1 #存储路径个数,需要和store_path个数匹配
    store_path0=/data2/storage #存储路径
    http.need_find_content_type=true #从文件扩展名查找文件类型(nginx时为true)
    #include http.conf #开启http服务


    4.配置nginx(nginx的listen端口一定要和storage的http端口相同)
    vim /usr/local/nginx/conf/nginx.conf

    10.240.37.87的nginx.conf配置如下:

    user nobody;

    worker_processes 4;

    worker_rlimit_nofile 65535;

    error_log /usr/local/nginx/logs/all_error.log;

    pid /usr/local/nginx/logs/nginx.pid;

    worker_connections 10240;
    }
    http {
    include mime.types;
    default_type application/octet-stream;
    error_page 400 403 500 502 503 504 /50x.html;

    server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    client_max_body_size 300m;
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 120;

    gzip off;
    gzip_static on;
    gzip_min_length 1k;
    gzip_http_version 1.0;
    gzip_comp_level 2;
    gzip_disable "MSIE [1-6].";
    gzip_vary on;

    proxy_redirect off;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_connect_timeout 90;
    proxy_send_timeout 90;
    proxy_read_timeout 90;
    proxy_buffer_size 16k;
    proxy_buffers 4 64k;
    proxy_busy_buffers_size 128k;
    proxy_temp_file_write_size 128k;

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';

    access_log /usr/local/nginx/logs/all_access.log main;


    proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2 keys_zone=http-cache:5m

    max_size=100m inactive=12h;
    proxy_temp_path /var/cache/nginx/proxy_cache/tmp;


    server {

    listen 8080;
    server_name localhost;
    server_name_in_redirect off;

    access_log logs/storage_access.log main;
    error_log logs/storage_error.log;

    location /G1/M00 {
    root /data1/storage/data;
    ngx_fastdfs_module;
    }

    }

    }


    10.240.37.90的nginx.conf基本配置不变,只需修改server里边location的root路径就行:

    server {

    listen 8080;
    server_name localhost;
    server_name_in_redirect off;

    access_log logs/storage_access.log main;
    error_log logs/storage_error.log;

    location /G2/M00 {
    root /data2/storage/data;
    ngx_fastdfs_module;
    }

    }

    5.建立M00至存储目录的符号连接
    10.240.37.87执行 ln -s /data1/storage/data /data1/storage/data/M00
    10.240.37.90执行 ln -s /data2/storage/data /data2/storage/data/M00


    6.启动顺序(注意关闭防火墙和seslinux):

    /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

    /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

    /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf


    7.测试文件是否可以上传下载:

    (1)修改一台机器的client.conf配置文件:
    base_path=/data1/tracker #日志存放路径
    tracker_server=10.240.37.87:22122 #tracker服务器IP地址和端口号
    http.tracker_server_port=8081 #tracker服务器的http端口号

    (2)执行如下操作:
    [root@localhost fdfs]# /usr/local/bin/fdfs_test /etc/fdfs/client.conf upload /usr/local/test/2007119124413448_2.jpg
    This is FastDFS client test program v5.01

    [2015-07-06 18:44:52] DEBUG - base_path=/tmp, connect_timeout=30, network_timeout=60, tracker_server_count=1, anti_steal_token=0, anti_steal_secret_key

    example file url: http://10.240.37.90:8081/G2/M00/00/00/CvAlWlWaXCSAXfcKAAF3qJ0P44M093_big.jpg

    然后下载的话 把返回的80801改成8080即可访问,因为tracker的http端口如果不做负载均衡的话是不提供http服务的。
    浏览器访问地址为:http://10.240.37.90:8080/G2/M00/00/00/CvAlWlWaXCSAXfcKAAF3qJ0P44M093_big.jpg


    8.注意事项与所遇到的错误:

    (1)清掉防火墙规则
    sudo iptables -F

    (2)注意include和#之间不能有空格
    #include http.conf

    (3)测试文件是否可以上传下载
    /usr/local/bin/fdfs_test /etc/fdfs/client.conf upload /usr/local/test/2007119124413448_2.jpg

    下载返回的地址:
    wget http://10.240.37.90:8080/G2/M00/00/00/CvAlWlWWTqqAeg8WAAF3qJ0P44M256_big.jpg


    测试报错:
    HTTP request sent, awaiting response... 500 Internal Server Error

    在linux 下 使用这个命令增加进程打开的文件句柄。
    ulimit -SHn 51200

    并修改nginx配置文件的worker_connections 10240;

    测试配置文件是否修改正确
    /usr/local/nginx/sbin/nginx -t

    重启nginx
    /usr/local/nginx/sbin/nginx -s reload


    查看nginx 的错误日志 /usr/local/nginx/logs/error.log

    /usr/local/nginx/html/50x.html" failed (24: Too many open files)

    cento 中 ulimit -n 为1024, 当Nginx连接数超过1024时,error.log中就出现以上错误

    解决方法是:


    修改/etc/security/limits.conf


    在 /etc/security/limits.conf 中加入以下内容:

    * soft nofile 655360
    * hard nofile 655360

    星号代表全局, soft为软件,hard为硬件,nofile为<type>这里指可打开文件数。

    另外,要使 limits.conf 文件配置生效,必须要确保 pam_limits.so 文件被加入到启动文件中。查看 /etc/pam.d/login 文件中有:
    session required /lib/security/pam_limits.so

    修改完重新登录就可以见到效果,可以通过 ulimit -n

    然后再修改 /usr/local/nginx/conf/nginx.conf

    worker_rlimit_nofile 65535;

    worker_connections 10240;


    然后报400错误
    400 Bad Request
    Request Header Or Cookie Too Large
    查看日志报错如下:
    "/usr/local/nginx/html/favicon.ico" failed (2: No such file or directory)

    解决方法,增大请求缓冲,编辑nginx.conf,修改下面两个配置项为:
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    重启即可。

    备注:如果有多个tracker可配置nginx+keepalived做前端下载上传的负载均衡.
