CentOS 6.4 安装 FastDFS、使用Nginx作为文件访问WEB服务器

色胃康胶囊

　　安装环境：
1. CentOS-6.4-i386
2. FastDFS_v4.06
3. fastdfs-nginx-module_v1.15
4. Nginx-1.5.6（安装见此）
5. libevent-2.0.21-stable
　　tracker server  IP：192.168.1.11
　　storage1 server IP：192.168.1.12 group1
　　storage2 server IP：192.168.1.13 group2
　　storage3 server IP：192.168.1.14 group2
　　1. CentOS系统初始化：
    #yum预装常用的服务器软件
      yum -y install gcc gcc-c++


　　2. 系统操作环境的设置
    #软件安装包存储
      /usr/local/src
    #libevent安装目录
      /usr/local/libevent
　　#fastdfs安装目录
      /usr/local/fastdfs
    #nginx安装目录
      /usr/local/nginx
　　3. 安装libevent（ fastdfs在编译源程序时fastdfs内部调用libevent的处理机制,,需要用到libevent一些依赖文件,否则编译fastdfs会出错）
    #卸载系统自带libevent，自带版本过低，安装fastdfs会出错
      1> rpm -qa|grep libevent
      2> yum remove libevent*
    #下载安装libevent：
      1> wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
      2> tar -zxvf libevent-2.0.21-stable.tar.gz
      3> cd libevent-2.0.21-stable
      4> ./configure --prefix=/usr/local/libevent
      5> 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
　　4. 安装FastDFS
    1> wget http://fastdfs.googlecode.com/files/FastDFS_v4.06.tar.gz
    2> tar -zxvf FastDFS_v4.06.tar.gz
    3> cd FastDFS
    4> #由于定义/usr/local/fastdfs为fastdfs安装目录,所以需要修改make.sh
           vi make.sh
           #内容更改如下
　　TARGET_PREFIX=/usr/local 修改为 /usr/local/fastdfs
           将/etc/fdfs 全部替换为 /usr/local/fastdfs/conf
    5> #安装
           ./make.sh C_INCLUDE_PATH=/usr/local/libevent/include LIBRARY_PATH=/usr/local/libevent/lib
           ./make.sh install
　　5. 配置Tracker
①创建tracker目录保存运行日志
     mkdir -m 777 -p /home/fastdfs/tracker
②修改tracker.conf配置
  vim /usr/local/fastdfs/conf/tracker.conf
  修改内容如下所示
　　# the tracker server port
port=22122
# the base path to store data and log files
base_path=/home/yuqing/fastdfs -> base_path=/home/fastdfs/tracker #日志目录
#开启自定义server ID取代ip形式,方便内部网络服务器更换ip#**此方式要重点理解，4.0以后新特性
use_storage_id = true #使用server ID作为storage server标识
storage_ids_filename = storage_ids.conf #  
id_type_in_filename = id #文件名反解析中包含server ID,以前是ip
　　

　　③移动storage_ids.conf文件
     cp -r /usr/local/src/FastDFS/conf/storage_ids.conf /usr/local/fastdfs/conf/
④编辑storage服务器ID与IP地址的对应关系
     vim /usr/local/fastdfs/conf/storage_ids.conf
修改内容如下所示
　　#  
100001          group1           192.168.1.12
100002          group2           192.168.1.13
100003          group2           192.168.1.14
　　⑤编辑启动脚本
  vim /etc/init.d/fdfs_trackerd
  启动脚本内容如下
　　#!/bin/bash
#
# fdfs_storaged Starts fdfs_storaged
#
#
# chkconfig: 2345 99 01
# description: FastDFS storage server
### BEGIN INIT INFO
# Provides: $fdfs_storaged
### END INIT INFO
# Source function library.
. /etc/init.d/functions
FastDfs='/usr/local/fastdfs'
CONF="$FastDfs/conf/storage.conf"
if [ ! -f $CONF ]; then
  echo "file $CONF does not exist!"
  exit 2
fi
PRG="$FastDfs/bin/fdfs_storaged"
if [ ! -f $PRG ]; then
  echo "file $PRG does not exist!"
  exit 2
fi
Stop="$FastDfs/bin/stop.sh"
if [ ! -f $Stop ]; then
  echo "file $Stop does not exist!"
  exit 2
fi
Restart="$FastDfs/bin/restart.sh"
if [ ! -f $Restart ]; then
  echo "file $Restart does not exist!"
  exit 2
fi
RETVAL=0
start() {
    echo -n $"Starting FastDFS storage server: "
    $PRG $CONF &
    RETVAL=$?
    echo
    return $RETVAL
}
stop() {
    echo -n $"Stop FastDFS storage server: "
    $Stop $PRG $CONF
    RETVAL=$?
    return $RETVAL
}
rhstatus() {
    status fdfs_storaged
}
restart() {
        $Restart $PRG $CONF &
}
case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  status)
    rhstatus
    ;;
  restart|reload)
    restart
    ;;
  condrestart)
    restart
    ;;
  *)
    echo $"Usage: $0 {start|stop|status|restart|condrestart}"
    exit 1
esac
exit $?
　　

　　⑥给启动脚本增加权限
     chmod 777 /etc/init.d/fdfs_storaged
   启动storage
     service fdfs_storaged restart
   接下来会出现很多mkdir data path，这是系统在创建数据目录，如下图所示
   
⑦启动成功，加入开机启动
   vim /etc/rc.d/rc.local
   加入内容如下
   service fdfs_storaged start
　　7. 安装nginx（仅Storage）    #创建nginx日志目录
      mkdir -m 777 -p /home/www/logs
    #安装nginx必需的库：zlib-devel openssl-devel pcre
yum -y install zlib-devel openssl-devel
      #手动安装pcre
      1> wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.33.tar.gz
      2> tar -zxvf pcre-8.33.tar.gz
      3> cd pcre-8.33
      4> ./configure
      5> make && make install
     6> ln -s /usr/local/lib/libpcre.so.1 /lib
#安装nginx
      1> wget http://nginx.org/download/nginx-1.5.6.tar.gz
      2> tar -zxvf nginx-1.5.6.tar.gz
      3> cd nginx-1.5.6
      4> ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
      5> make && make install
     #检查nginx配置是否正确
       /usr/local/nginx/sbin/nginx -t
     #出现以下类似信息表示配置正确
      
     #查看nginx编译选项
       /usr/local/nginx/sbin/nginx -V
     #编辑启动脚本
       vim /etc/init.d/fdfs_storaged
       #启动脚本内容如下
　　#!/bin/sh
