安装

代码如下

tar -zxvf gm.tar.gz
tar -zxvf GraphicsMagick-1.3.12.tar.gz
cd GraphicsMagick-1.3.12
./configure –prefix=/usr/local/gm
make && make install

tar -zxvf LuaJIT-2.0.0-beta10.tar.gz
cd LuaJIT-2.0.0-beta10
make && make install PREFIX=/usr/local/lj2
ln -sf luajit-2.0.0-beta10 /usr/local/lj2/bin/luajit

unzip simpl-ngx_devel_kit-v0.2.19-0-g8dd0df5.zip

tar -zxvf chaoslawful-lua-nginx-module-v0.9.2-61-ge4e085f.tar.gz

unzip agentzh-echo-nginx-module-v0.49-1-g84feae9.zip

tar -zxvf ngx_cache_purge-1.6.tar.gz

设置环境变量

代码如下
export LUAJIT_LIB=/usr/local/lj2/lib export LUAJIT_INC=/usr/local/lj2/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-1.3.16; PATH=$GM_HOME/bin:$PATH; export PATH export GM_HOME

使环境变量生效：source /etc/profile

代码如下

tar -zxvf nginx-1.2.1.tar.gz
cd nginx-1.2.1
./configure –prefix=/usr/local/nginx5 –user=www –group=www –with-http_stub_status_module –add-module=/root/gm/simpl-ngx_devel_kit-8dd0df5 –with-ld-opt=-Wl,-rpath,/usr/local/lj2/lib –add-module=/root/gm/ngx_cache_purge-1.6 –with-http_perl_module –add-module=/root/gm/chaoslawful-lua-nginx-module-e4e085f –add-module=/root/gm/agentzh-echo-nginx-module-84feae9 –with-pcre

如果报错，很可能是没有安装lua和lua-devel
直接yum安装即可：

代码如下
# yum install lua lua-devel
