LNMP平滑升级nginx并安装ngx_lua模块教程

#ngx_lua module项目地址

https://github.com/chaoslawful/lua-nginx-module

在LNMP安装包后，重编译nginx，并添加ngx_lua模块



1」Download



wget http://luajit.org/download/LuaJIT-2.0.4.tar.gz

wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz

wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.9.16.tar.gz

wget http://nginx.org/download/nginx-1.9.2.tar.gz



2」安装LuaJIT



tar -zxvf LuaJIT-2.0.4.tar.gz

cd LuaJIT-2.0.4

make

make install

export LUAJIT_LIB=/usr/local/lib

export LUAJIT_INC=/usr/local/include/luajit-2.0



3」copy模块



cp v0.2.19.tar.gz /usr/local/src

cp v0.9.16.tar.gz /usr/local/src

tar -zxvf v0.2.19.tar.gz

tar -zxvf v0.9.16.tar.gz

 解压下载下来的ngx_devel_kit以及lua-nginx-module到/usr/local/src目录下，即

/usr/local/src/lua-nginx-module-0.9.16/

 /usr/local/src/ngx_devel_kit-0.2.19/



 3」重新编译Nginx



tar -zxvf nginx-1.9.2.tar.gz

解压nginx包，configure一下（参考LNMP安装包，未加其他修改）

./configure –user=www –group=www –prefix=/usr/local/nginx –with-ld-opt="-Wl,-rpath,$LUAJIT_LIB" –with-http_stub_status_module –with-http_ssl_module –with-http_gzip_static_module –with-ipv6 \

–add-module=/usr/local/src/lua-nginx-module-0.9.16/ \

–add-module=/usr/local/src/ngx_devel_kit-0.2.19/

OK后make，别make install，否则就覆盖安装



4」备份替换



make完后在objs目录下多了个nginx，即新版本的程序

 备份旧的nginx程序

cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak



新nginx程序覆盖旧的

cp objs/nginx /usr/local/nginx/sbin/nginx



如果提示“cp:cannot create regular file `/usr/local/nginx/sbin/nginx’: Text file busy”

建议使用如下语句cp

cp -rfp objs/nginx /usr/local/nginx/sbin/nginx



测试新的nginx程序是否正确

/usr/local/nginx/sbin/nginx -t

nginx: theconfiguration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx:configuration file /usr/local/nginx/conf/nginx.conf test issuccessful



平滑重启nginx

/usr/local/nginx/sbin/nginx -s reload



查看ngixn版本及其编译参数

/usr/local/nginx/sbin/nginx -V



「问题解决」

1.如遇到找不到库文件

echo “/usr/local/lib” > /etc/ld.so.conf.d/usr_local_lib.conf

ldconfig

即可

2./usr/local/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory  

在 Nginx 编译时，需要指定 RPATH，记得加入下面选项：

./configure –with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"  

或者export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
