FastDFS文件服务器服务器实现双机热备

两台文件fastDFS文件服务器
服务器A: 192.168.10.157
服务器B:192.168.10.158
上面实现目的：增加一台fastDFS备份服务器（192.168.10.158），做为fastDFS文件服务器（192.168.10.157）的从服务器，这两台fastDFS文件服务器之间实现双机热备。
即：从服务器（192.168.10.158）上面数据永远与主服务器（192.168.10.157）上面数据保持同步，并且随着主服务器（192.168.10.157）上面数据的变化而变化。
环境说明
1、fastDFS主服务器 主机名称：Master
系统：CentOS 6.6  IP：192.168.10.157    FastDFS_v5.03.+nginx-1.6.2+libevent-2.0.21-stable
2  fastDFS从服务器 主机名称 ：Slave
系统：CentOS 6.6  IP：192.168.10.158    FastDFS_v5.03.+nginx-1.6.2+libevent-2.0.21-stable
备注：作为主从服务器的fastDFS和nginx 版本建议使用同一版本！
开始：
一、安装libevent
说明：在两台MySQL服务器192.168.10.157和192.168.21.158上分别进行如下操作，
1、下载libevent-2.0.21-stable.tar.gz
          http://sourceforge.net/ 
2、解压并安装配置
tar  -zxvf libevent-2.0.21-stable.tar.gz
cd  libevent-2.0.21-stable
mkdir -p /usr/local/libevnet
./configure --prefix=/usr/local/libevent
make && make install
#为libevent创建软链接到/lib库下，64位系统对应/lib64
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5

ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
到此，libevent安装完成！
二、安装fastDFS文件服务器
1、下载lFastDFS_v5.03.tar.gz
        http://sourceforge.net/projects/fastdfs/
2、解压并安装配置
tar zxvf FastDFS_v5.03.tar.gz
cd FastDFS
vim make.sh
#WITH_LINUX_SERVICE=1  /取消此行的注释
./make.sh
./make.sh install
到此，fastDFS安装完成！
涉及ip的文件: /etc/fdfs/storage.conf          /etc/fdfs/client.conf        /etc/fdfs/mod_fastdfs.conf
涉及目录的文件: /etc/fdfs/storage.conf    /etc/fdfs/tracker.conf      /etc/fdfs/client.conf      /etc/fdfs/mod_fastdfs.conf
#trackerd
/usr/local/bin/stop.sh  /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
/usr/local/bin/restart.sh  /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
#storaged
/usr/local/bin/stop.sh  /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

/usr/local/bin/restart.sh  /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
3、建立存储路径并配置fastDFS_v5.03

  mkdir -p  /www/geebook_storage    #建立storage存储目录
  mkdir -p  /www/geebook_tracker      #建立tracker调度器目录
  mkdir -p  /www/geebook_client          #建立client客户端目录
  cp /etc/fdfs/storage.conf /etc/fdfs/storage.conf-bak    #备份配置文件
  cp /etc/fdfs/tracker.conf /etc/fdfs/tracker.conf-bak      #备份配置文件
  cp /etc/fdfs/client.conf  /etc/fdfs/client.conf-bak          #备份配置文件
  vi  /etc/fdfs/storage.conf                      #修改storage配置文件修改参数
      base_path=/www/geebook_stoarge    # the base path to store data and log files
      store_path0=/www/geebook_storage  # store_path#, based 0, if store_path0 not exists, it's value is base_path
      tracker_server=192.168.10.157          # 指定tracker server地址 可以有多个同步的IP
      tracker_server=192.168.10.158
  vi /etc/fdfs/tracker.conf    #修改tracker配置文件修改参数

        base_path=/www/geebook_tracker    # the base path to store data and log files

  vi /etc/fdfs/client.conf    #修改client配置文件修改参数
        base_path=/www/geebook_client      # the base path to store log files
        tracker_server=192.168.10.157          # 指定tracker server地址 可以有多个同步的IP
        tracker_server=192.168.10.158 

三、fastdfs-nginx-mod-install 安装与配置
      1、安装准备工作    ####重点#####
 cat /etc/fdfs/mod_fastdfs.conf  中必须要有 #include http.conf ,
  cat /etc/fdfs/client.conf      中可以有 #include http.conf , 表示注释 ##include http.conf
#####增加用户和组  adduser --system --no-create-home --disabled-password --disabled-login --group nginx
groupadd nginx
useradd -g nginx -s /bin/false -M nginx
2、下载安装包和相关的依赖包并建立安装目录
 # wget http://nginx.org/download/nginx-1.6.2.tar.gz
# rewrite 模块需要 pcre 库    # wget http://downloads.sourceforge.net/project/pcre/pcre/8.36/pcre-8.36.zip
# ssl 功能需要 openssl 库      # wget http://www.openssl.org/source/openssl-1.0.2.tar.gz
# gzip 模块需要 zlib 库          # wget http://zlib.net/zlib-1.2.8.tar.gz
# ngx_cache_purge 清除缓存
# wget --no-check-certificate https://github.com/FRiCKLE/ngx_cache_purge/archive/master.zip -O ngx_cache_purge-master.zip
# nginx-echo
# wget --no-check-certificate https://github.com/agentzh/echo-nginx-module/archive/master.zip -O echo-nginx-module-master.zip
# nginx-upstream-fair 
# wget --no-check-certificate https://github.com/gnosek/nginx-upstream-fair/archive/master.zip -O nginx-upstream-fair-master.zip
# fastdfs nginx module
# wget http://fastdfs.googlecode.com/files/fastdfs-nginx-module_v1.15.tar.gz

####centos install
yum -y install gcc g++ gcc-c++ autoconf automake make unzip
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
mkdir -p /usr/local/nginx/conf                    mkdir -p /usr/local/nginx/conf/vhost
mkdir -p /usr/local/nginx/logs                    mkdir -p /usr/local/nginx/cache/body
mkdir -p /usr/local/nginx/cache/fastcgi      mkdir -p /usr/local/nginx/cache/uwsgi
mkdir -p /usr/local/nginx/cache/scgi          mkdir -p /usr/local/nginx/cache/proxy
 3、配置安装
  cd  /usr/src/nginx
  tar zxvf nginx-1.6.2.tar.gz
  tar zxvf fastdfs-nginx-module_v1.16.tar.gz
 unzip ngx-cache-purge-master.zip
 unzip echo-nginx-module-master.zip
 unzip nginx-upstream-fair-master.zip
  cd nginx-1.6.2
./configure --prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--conf-path=/usr/local/nginx/conf/nginx.conf \
--error-log-path=/usr/local/nginx/logs/error.log \
--http-log-path=/usr/local/nginx/logs/access.log \
--lock-path=/usr/local/nginx/logs/nginx.lock \
--pid-path=/usr/local/nginx/logs/nginx.pid \
--http-client-body-temp-path=/usr/local/nginx/cache/body \
--http-fastcgi-temp-path=/usr/local/nginx/cache/fastcgi \
--http-uwsgi-temp-path=/usr/local/nginx/cache/uwsgi \
--http-scgi-temp-path=/usr/local/nginx/cache/scgi \
--http-proxy-temp-path=/usr/local/nginx/cache/proxy \
--with-pcre-jit \
--with-http_random_index_module \
--with-file-aio \
--with-debug \
--with-http_addition_module \
--with-http_gzip_static_module \
--with-http_realip_module \
--with-http_stub_status_module \
--with-http_sub_module \
--with-poll_module \
--with-http_ssl_module \
--add-module=/usr/src/nginx/echo-nginx-module-master \
--add-module=/usr/src/nginx/nginx-upstream-fair-master \
--add-module=/usr/src/nginx/ngx_cache_purge-master \
--add-module=/usr/src/nginx/fastdfs-nginx-module/src
make

make install

*************************** 配置nginx mod_fastdfs.conf***************************
/etc/fdfs/mod_fastdfs.conf 中必须要有 #include http.conf    注意不是注释 如果是注释是：      ##include http.conf
cp /usr/src/nginx/fastdfs-nginx-module/src/mod_fastdfs.conf    /etc/fdfs/    #复制配置文件到/etc/fdfs/ 
cp /etc/fdfs/mod_fastdfs.conf  /etc/fdfs/mod_fastdfs.conf-bak                        #备份初始配置文件
mkdir -p /www/logs
vi /etc/fdfs/mod_fastdfs.conf
  base_path=/www/logs  #the base path to store log files 存放日志文件
  store_path0=/www/geebook_storage  # must same as storage.conf 
  url_have_group_name = ture
  tracker_server=192.168.10.157:22122
  tracker_server=192.168.10.158:22122
  #include http.conf
*************************** 配置nginx.conf***************************
cp    /usr/local/nginx/conf/nginx.conf    /usr/local/nginx/conf/nginx.conf-bak    #备份配置文件

八、测试fastDFS主从服务器双机热备是否成功
1、分别进入fastDFS主从服务器启动各服务
#trackerd
/usr/local/bin/stop.sh  /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
/usr/local/bin/restart.sh  /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
tail -f  /www/geebook_storage/logs/*.log   
#storaged
/usr/local/bin/stop.sh  /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

/usr/local/bin/restart.sh  /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
tail -f  /www/geebook_tracker/logs/*.log   
#nginx
chown -R nginx.nginx /usr/local/nginx/logs/
/usr/local/nginx/sbin/nginx -s stop
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
tail -f  /usr/local/nginx/logs/*.log   

2、在主从服务器分别测试上传下载删除查询文件
在主服务器上传文件：/usr/local/bin/fdfs_upload_file  /etc/fdfs/client.conf  /www/geebook_client/a.jpg
返回信息：group1/M00/00/00/wKgKnVTv-lqADpl3AAAs_VD7qBc394.jpg
用浏览器访问http://192.168.10.157/group1/M00/00/00/wKgKnVTv-lqADpl3AAAs_VD7qBc394.jpg
用浏览器访问http://192.168.10.158/group1/M00/00/00/wKgKnVTv-lqADpl3AAAs_VD7qBc394.jpg
下载文件：/usr/local/bin/fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKgKnVTv-lqADpl3AAAs_VD7qBc394.jpg
删除文件：/usr/local/bin/fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/wKgKnVTv-lqADpl3AAAs_VD7qBc394.jpg

用浏览器访问http://192.168.10.158/group1/M00/00/00/wKgKnlTv-2mAdfNQAAA06ICuy-Q058.jpg
用浏览器访问http://192.168.10.157/group1/M00/00/00/wKgKnlTv-2mAdfNQAAA06ICuy-Q058.jpg
下载文件：/usr/local/bin/fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKgKnlTv-2mAdfNQAAA06ICuy-Q058.jpg  xxx.jpg
删除文件：/usr/local/bin/fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/wKgKnlTv-2mAdfNQAAA06ICuy-Q058.jpg
查询服务器 /usr/local/bin/fdfs_monitor /etc/fdfs/client.conf
删除无效的存储服务器,active时,禁止删除 /usr/local/bin/fdfs_monitor /etc/fdfs/client.conf delete group1 10.0.250.103
####浏览器访问http://存储服务器ip:group1/M00/
