tengine安装ngx_http_lua_module
从http://luajit.org/download.html下载的luajit来安装tengine上，启动时报错如下
nginx: [alert] detected a LuaJIT version which is not OpenResty's; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty's LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)
先卸载原有luajit
make uninstall
然后从https://github.com/openresty/luajit2下载
git clone https://github.com/openresty/luajit2
make && make install
tengine2.0.3下
./configure --with-http_lua_module \ --with-luajit-lib=/usr/local/lib/ \ --with-luajit-inc=/usr/local/include/luajit-2.1/ \ --with-lua-inc=/usr/local/include/luajit-2.1/ \ --with-lua-lib=/usr/local/lib/ make && make install
问题：
[root@localhost sbin]# ./nginx -m ./nginx: error while loading shared libraries: libluajit-***.so.2: cannot open shared object file: No such file or directory
使用一下命令解决：
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf ldconfig
