移植 Nginx+PHP(FastCGI) 到 ARM Linux （一）

环境

交叉编译环境：Ubuntu12.04 64位
交叉编译器：arm-linux-gcc-4.9.x
ARM系统：Linux imx6dlsabresd 3.14.52-1.1.1_ga+gdb1bcba #5 SMP PREEMPT Wed Mar 15 12:15:01 CST 2017 armv7l GNU/Linux

Nginx 交叉编译

1、 预先下载好文件
a，nginx-1.12.1.tar.gz
b，pcre-8.30.tar.gz（不要下最新的pcre2-**.tar.gz）
c，zlib-1.2.11.tar.gz

说明：我这里不需要支持https访问，所以下面不会编译openssl模块。

2、 解压文件

robinson@robinson-vm:~/Downloads/ForTest$ lsnginx-1.12.1.tar.gz  pcre-8.30.tar.gz  zlib-1.2.11.tar.gzrobinson@robinson-vm:~/Downloads/ForTest$ tar -xzvf nginx-1.12.1.tar.gzrobinson@robinson-vm:~/Downloads/ForTest$ tar -xzvf pcre-8.30.tar.gzrobinson@robinson-vm:~/Downloads/ForTest$ tar -xzvf zlib-1.2.11.tar.gzrobinson@robinson-vm:~/Downloads/ForTest$ lsnginx-1.12.1         pcre-8.30         zlib-1.2.11nginx-1.12.1.tar.gz  pcre-8.30.tar.gz  zlib-1.2.11.tar.gz 

3、 编写configure配置文件脚本nginx_configure.sh

#!/bin/shBUILD_PATH=/home/nginx_armCC_PATH=/home/robinson/Downloads/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-gccCPP_PATH=/home/robinson/Downloads/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-g++./configure \  --prefix=$BUILD_PATH \  --with-zlib=/home/robinson/Downloads/ForTest/zlib-1.2.11 \  --with-pcre \  --with-pcre=/home/robinson/Downloads/ForTest/pcre-8.30 \  --with-pcre-jit \  --with-cc=$CC_PATH \  --with-cpp=$CPP_PATH

说明：
  此脚本文件存放于nginx-1.12.1文件夹下，需要自行添加可执行权限。
  关于BUILD_PATH，这是编译好的nginx存放位置。
  关于CC_PATH、CPP_PATH是交叉编译器路径，这里填的完整路径，如果配置好环境变量可以直接写：arm-linux-gnueabihf-gcc、arm-linux-gnueabihf-g++，大家需要根据自己的实际情况作调整。
  前面提到了我没有配置openssl模块编译。

4、修改几处源代码（nginx-1.12.1文件夹下）
  1). auto/cc/name

if [ "$NGX_PLATFORM" != win32 ]; thenngx_feature="C compiler"ngx_feature_name=#ngx_feature_run=yesngx_feature_run=no   ==>set to no to skip checkngx_feature_incs=ngx_feature_path=

  2). auto/types/sizeof

(1)ngx_test="$CC $CC_TEST_FLAGS $CC_AUX_FLAGS   ==> ngx_test="gcc $CC_TEST_FLAGS $CC_AUX_FLAGS(2)checking for $ngx_type size  END  ngx_size= ==> ngx_size=4

  3). auto/lib/pcre/make

./configure --disable-shared $PCRE_CONF_OPT ==>./configure --disable-shared $PCRE_CONF_OPT --host=arm

  4). src/os/unix/ngx_errno.h

(新增)#define NGX_SYS_NERR 333(新增)#ifndef NGX_HAVE_SYSVSHM(新增)#define NGX_HAVE_SYSVSHM 1(新增)#endiftypedef int               ngx_err_t;

  5). src/core/ngx_rwlock.c

12行 #if (NGX_HAVE_ATOMIC_OPS) ==> #if (!NGX_HAVE_ATOMIC_OPS)

5、执行./nginx_configure.sh

robinson@robinson-vm:~/Downloads/ForTest/nginx-1.12.1$ sudo ./nginx_configure.shchecking for OS + Linux 3.13.0-32-generic x86_64checking for C compiler ... found + gcc version: 4.9.2 20140904 (prerelease) (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) checking for gcc -pipe switch ... foundchecking for -Wl,-E switch ... found*********************************************************checking for struct tm.tm_gmtoff ... foundchecking for struct dirent.d_namlen ... not foundchecking for struct dirent.d_type ... foundchecking for sysconf(_SC_NPROCESSORS_ONLN) ... foundchecking for openat(), fstatat() ... foundchecking for getaddrinfo() ... foundcreating objs/MakefileConfiguration summary  + using PCRE library: /home/robinson/Downloads/ForTest/pcre-8.30  + OpenSSL library is not used  + using zlib library: /home/robinson/Downloads/ForTest/zlib-1.2.11  nginx path prefix: "/home/nginx_arm"  nginx binary file: "/home/nginx_arm/sbin/nginx"  nginx modules path: "/home/nginx_arm/modules"  nginx configuration prefix: "/home/nginx_arm/conf"  nginx configuration file: "/home/nginx_arm/conf/nginx.conf"  nginx pid file: "/home/nginx_arm/logs/nginx.pid"  nginx error log file: "/home/nginx_arm/logs/error.log"  nginx http access log file: "/home/nginx_arm/logs/access.log"  nginx http client request body temporary files: "client_body_temp"  nginx http proxy temporary files: "proxy_temp"  nginx http fastcgi temporary files: "fastcgi_temp"  nginx http uwsgi temporary files: "uwsgi_temp"  nginx http scgi temporary files: "scgi_temp"

6、make

robinson@robinson-vm:~/Downloads/ForTest/nginx-1.12.1$ sudo make

7、make install

robinson@robinson-vm:~/Downloads/ForTest/nginx-1.12.1$ sudo make install

生成的文件在/home/nginx_arm

8、打包交叉编译好的文件

robinson@robinson-vm:/home$ lsnginx_arm  robinsonrobinson@robinson-vm:/home$ sudo tar -jcvf nginx_arm.tar.bz2      nginx_arm/nginx_arm/nginx_arm/html/nginx_arm/html/index.htmlnginx_arm/html/50x.htmlnginx_arm/logs/nginx_arm/sbin/nginx_arm/sbin/nginxnginx_arm/conf/nginx_arm/conf/fastcgi_params.defaultnginx_arm/conf/nginx.conf.defaultnginx_arm/conf/scgi_params.defaultnginx_arm/conf/nginx.confnginx_arm/conf/uwsgi_params.defaultnginx_arm/conf/fastcgi.confnginx_arm/conf/koi-utfnginx_arm/conf/mime.typesnginx_arm/conf/koi-winnginx_arm/conf/fastcgi.conf.defaultnginx_arm/conf/fastcgi_paramsnginx_arm/conf/mime.types.defaultnginx_arm/conf/uwsgi_paramsnginx_arm/conf/win-utfnginx_arm/conf/scgi_paramsrobinson@robinson-vm:/home$ lsnginx_arm  nginx_arm.tar.bz2  robinson

9、将nginx_arm.tar.bz2拷贝到arm板子上，注意一定要在/home下解压（路径必须和交叉编译时的路径一致）

root@imx6dlsabresd:/home# lsnginx_arm  root

10、启动nginx

root@imx6dlsabresd:/home/nginx_arm# /home/nginx_arm/sbin/nginx或root@imx6dlsabresd:/home/nginx_arm# /home/nginx_arm/sbin/nginx -c /home/nginx_arm/conf/nginx.conf

11、测试，用局域网内的浏览器访问Arm板子的ip，看到下面界面，说明nginx移植成功了。

后记

su命令会获取root权限但仍使用用户的环境变量。
sudo命令会获取root权限并使用root的环境变量。
