ftp+nginx+lua_Nginx+GraphicsMagick来实现目录浏览、实时缩略图
?
一、FTP服務器安裝配置
1、rpm -ivh vsftpd-2.2.2-11.el6_4.1.i686.rpm
2、service vsftpd start
3、chkconfig vsftpd on
4、配置
cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.bak
vim /etc/vsftpd/vsftpd.conf
12 anonymous_enable=NO 禁止匿名訪問
...
121 chroot_local_user=yes 禁錮登錄目錄
122 local_root=/usr/local/nginx/html/test 改登錄目錄為/usr/local/nginx/html/test
123 userlist_deny=NO 白名單生效
124 max_clients=20 最大并發客戶端
125 max_per_ip=2 每ip最大并發
126 local_max_rate=100000 限制下載速度
5、白名單配置
tail -1 /etc/vsftpd/user_list
test
6、添加FTP用戶、用戶組及相關權限
# groupadd test
添加test用戶組，用來承載我們的FTP授權用戶。
# useradd -g test -M -d /usr/local/nginx/html/test -s /sbin/nologin test
使用-g參數將它歸集到test用戶組下，-M參數不設置它的主目錄（沒有-M參數/home里會有個test文件夾，這個文件夾沒多少實際用處，所以不用設置），-d參數設定它的初始登入目錄為/usr/local/nginx/html/test，-s參數設定它不需要登陸系統/sbin/nologin。
7、修改FTP用戶密碼及目錄權限
passwd test
chown –R /usr/local/nginx/html/test
8、重啟
service vsftpd restart
9、訪問測試
?? ftp://test:123456@192.168.1.1
二、Nginx+lua_Nginx+GraphicsMagick來實現實時縮略圖
安裝libpng
?? wget http://www.p_w_picpathmagick.org/download/delegates/libpng-1.6.2.tar.gz
tar xf libpng-1.6.21.tar.gz -C /usr/local/
./configure
make && make install
ln -s /usr/local/libpng-1.6.21/.libs/libpng16.so.16 /lib64/libpng16.so.16
安裝jpeg-9a
??? wget http://www.p_w_picpathmagick.org/download/delegates/jpegsrc.v9a.tar.gz
tar xf jpegsrc.v9a.tar.gz -C /usr/local/
./configure
make && make install
ln -s /usr/local/jpeg-9a/.libs/libjpeg.so.9 /lib64/libjpeg.so.9
1、安裝GraphicsMagick
wget http://sourceforge.net/projects/graphicsmagick/files/graphicsmagick/1.3.20/GraphicsMagick-1.3.20.tar.gz/download
tar -zxvf? GraphicsMagick-1.3.20.tar.gz
?
cd GraphicsMagick-1.3.20
?
./configure --prefix=/usr/local/GraphicsMagick
make && make install
2、下載luajit
a.下載
?
? wget http://luajit.org/download/LuaJIT-2.0.4.tar.gz
?
b.解壓
?
tar -zxvf LuaJIT-2.0.4.tar.gz
?
c.進入解壓目錄
?
cd LuaJIT-2.0.4
?
d.安裝
?
make
?
make install
?
e.建立軟連接
?
ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2
f.測試 luajit
?
退出編輯 ：Ctrl + D 保存退出
?
安裝 lua
1.首先確認是否安裝 readline
?rpm -qa|grep -i readline
?
yum安裝readline
?
?yum -y install readline-devel ncurses-devel
?
2.安裝lua
?
2.1 lua安裝
?
a.下載lua
?
? wget http://www.lua.org/ftp/lua-5.3.1.tar.gz
?
b.解壓lua-5.3.1.tar.gz
?
tar zxvf lua-5.3.1.tar.gz
?
c.進入解壓目錄
cd lua-5.3.1
?
d.安裝
?
make linux && makeinstall
?
或
?
make linux
?
make install
?
e。測試
?
lua命令：
?
在編輯模式中輸入：
?
print('Hi,this is? my first lua program!')
?
回車
?
問題：error while loading shared libraries: xxx.so.0:cannot open shared object file: No such file or directory
?
出現這類錯誤表示，系統不知道xxx.so放在哪個目錄下，這時候就要在/etc/ld.so.conf中加入xxx.so所在的目錄。
?
一般而言，有很多的so會存放在/usr/local/lib這個目錄底下，去這個目錄底下找，果然發現自己所需要的.so文件。
?
所以，在/etc/ld.so.conf中加入/usr/local/lib這一行，保存之后，再運行：/sbin/ldconfig –v更新一下配置即可。
?
?
?
?
cd /usr/src
?
3、下載 ?ngx_devel_kit 模塊
wget https://github.com/simpl/ngx_devel_kit/archive/master.zip
unzip master.zip
4、下載 lua-nginx-module 模塊
https://github.com/openresty/lua-nginx-module/archive/master.zip
unzip master.zip
5、下載echo
?https://github.com/agentzh/echo-nginx-module/zipball/master
unzip echo-nginx-module.zip?
6、下載cache
wget http://labs.frickle.com/files/ngx_cache_purge-2.1.tar.gz
tar -zxvf ngx_cache_purge-2.1.tar.gz
?
cd ngx_cache_purge-2.1
?
...
?
7、下載nginx
wget http://nginx.org/download/nginx-1.7.5.tar.gz
...
8、設置環境變量
export LUAJIT_LIB=/usr/local/lj2/lib
?
export LUAJIT_INC=/usr/local/include/luajit-2.0/
?
export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
?
export? PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
?
GM_HOME=/usr/local/GraphicsMagick;
?
PATH=$GM_HOME/bin:$PATH;
?
export PATH
?
export GM_HOME
?
source /etc/profile
?
9、nginx 編譯安裝
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --add-module=/usr/local/src/ngx_devel_kit-master --with-ld-opt=-Wl,-rpath,/usr/local/lib --add-module=/usr/local/src/ngx_cache_purge-2.3 --with-http_perl_module --add-module=/usr/local/src/echo-nginx-module --add-module=/usr/local/src/lua-nginx-module-master --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --user=nginx --group=nginx --with-http_ssl_module? --with-http_flv_module --with-http_gzip_static_module --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/tmp/nginx/client --http-proxy-temp-path=/var/tmp/nginx/proxy --http-fastcgi-temp-path=/var/tmp/nginx/fcgi --with-http_stub_status_module

yum -y install perl-devel perl-ExtUtils-Embed
?
?
?
10、nginx配置
