NGINX近两年的使用范围非常广泛，既可以作为HTTP负载均衡器，还可以作为PHP服务器，还能做HTTPS服务器，用途非常广泛，体积非常小巧，性能很高。很多Linux的Web服务器都部署了nginx。
但是如果使用了IBM的Power服务器，AIX系统，WebSphere中间件等IBM全家桶，很多linux用的很顺手的东西，到了AIX上都很难安装和部署。
虽然IBM对于这种软负载均衡器有自己的产品，比如IBM HTTP Server，但是使用起来仍然很复杂，不如nginx配置简单方便，而且最关键的是，IBM的产品都是要收费的，所以开源产品在AIX上仍然有它存在的意义。
如果在一台精简安装的AIX系统上装nginx需要安装大量的依赖包，由于AIX上没有像linux上有专门的yum管理工具，所以所有的依赖都要自己手动解决，虽然比较麻烦，但是能够自己手动控制依赖的版本。
如果只安装nginx，那么所有的依赖都选择最新的版本就好，但是其他的工具，比如WebSphere的概要文件管理器（/IBM/WebSphere/AppServer/bin/ProfileManagement/pmt.sh），可以使用图形界面，配置文件和命令行三种方式创建概要文件，但是最好用的还是图形界面，然而图形界面使用的eclipse爱用的awt，所以需要AIX系统安装了gtk2，而且还不能安装最新版的gtk，必须使用十年前很旧很旧的版本，而这样新旧版本就会和nginx的依赖发生冲突，所以要格外注意各个依赖包版本的选择，并以概要文件管理器为准。
安装nginx有两种方式：
1、安装预编译好的rpm包，无法自定义模块
2、自己编译nginx源码，并可以定制nginx的模块
下面先介绍安装rpm包，nginx最新版的rpm包可以去http://www.perzl.org/aix/index.php?n=Main.Nginx 下载，而且它所需的各个依赖包也可以在ftp://www.oss4aix.org/everything/RPMS/ 下载
对于AIX 7.1.0.0所需的nginx和所有合适版本的依赖包我都已经下载好，大家可以到下面这个连接直接下载压缩包，免去手动查找依赖选择版本的痛苦
http://download.csdn.net/download/lvshaorong/10264129
大概的依赖关系如下图所示，在安装的的时候还要注意版本，不要一位只选择最高版本，防止其他服务不兼容
按照上图所示的依赖关系安装相关的依赖包，最后安装nginx就可以实现，如下面这台机器是一台精简安装的AIX 7.1.0.0，预装软件只有下面几个
bash-4.3# oslevel
7.1.0.0
bash-4.3# rpm -qa
bash-4.3.30-1
tcl-8.4.7-3
tk-8.4.7-3
expect-5.42.1-3
AIX-rpm-7.1.2.15-2
然后是我提供的压缩包里的rpm包，解压后放到服务器上，如下
bash-4.3# ls
GeoIP-1.5.1-1.aix5.1.ppc.rpm
bzip2-1.0.6-1.aix5.1.ppc.rpm
expat-2.0.1-1.aix5.2.ppc.rpm
fontconfig-2.5.0-1.aix5.1.ppc.rpm
freetype2-2.3.9-1.aix5.2.ppc.rpm
gd-2.0.35-5.aix5.1.ppc.rpm
gettext-0.10.40-6.aix5.1.ppc.rpm
glib2-2.38.2-1.aix5.1.ppc.rpm
info-6.4-1.aix5.1.ppc.rpm
libXpm-3.5.12-1.aix6.1.ppc.rpm
libgcc-6.3.0-1.aix7.1.ppc.rpm
libgcrypt-1.8.2-1.aix5.2.ppc.rpm
libgpg-error-1.27-1.aix5.1.ppc.rpm
libiconv-1.15-1.aix5.1.ppc.rpm
libjpeg-6b-6.aix5.1.ppc.rpm
libpng-1.2.32-2.aix5.2.ppc.rpm
libxml2-2.9.7-1.aix5.1.ppc.rpm
libxslt-1.1.32-1.aix5.1.ppc.rpm
nginx-1.12.2-1.aix5.3.ppc.rpm
openssl-1.0.2l-1.aix5.1.ppc.rpm
pcre-8.41-1.aix5.1.ppc.rpm
pkg-config-0.25-1.aix5.1.ppc.rpm
readline-7.0-3.aix5.1.ppc.rpm
xorg-compat-aix-1.2-1.aix5.1.ppc.rpm
xz-libs-5.2.3-1.aix6.1.ppc.rpm
zlib-1.2.3-7.aix5.1.ppc.rpm
如果不是精简安装，那么有些包可能已经安装过了，就无需再次安装，除非遇到了版本太高或者太低不兼容的问题。比如目前AIX 官网给出的openssl就要比nginx要求的openssl版本要低。，所以需要用这个openssl直接覆盖掉以前安装的openssl。
我的完整安装过程日志如下,可以作为参考

二、根据源码编译nginx
如果要自己编译，就要在自己的AIX主机上安装编译环境，也就是GCC。注意通过官方提供的rpm包安装GCC之后nginx编译检查仍然通不过，需要将GCC软连接到CC才行。GCC所需的依赖包我也已经下载好，可以下载下面的压缩包，里面有这些rpm
gcc-6.3.0-1.aix7.1.ppc.rpm
gcc-cpp-6.3.0-1.aix7.1.ppc.rpm
gmp-5.1.3-2.aix6.1.ppc.rpm
info-6.4-1.aix5.1.ppc.rpm
libgcc-6.3.0-1.aix7.1.ppc.rpm
libiconv-1.15-1.aix5.1.ppc.rpm
libmpc-1.0.3-1.aix6.1.ppc.rpm
libstdcplusplus-6.3.0-1.aix7.1.ppc.rpm
mpfr-3.1.2-3.aix6.1.ppc.rpm
pcre-8.33-1.aix6.1.ppc.rpm
pcre-devel-8.33-1.aix6.1.ppc.rpm
readline-7.0-5.aix6.1.ppc.rpm
zlib-1.2.11-1.aix6.1.ppc.rpm
zlib-devel-1.2.11-1.aix6.1.ppc.rpm
下载地址：https://download.csdn.net/download/lvshaorong/10422859
其中pcre-devel和zlib-devel并不是编译器所需的依赖包，而是nginx的https模块所需的依赖包
将这几个包安装好，注意依赖顺序，其中gcc和gcc-cpp互相依赖，无法单独安装，方法是把这两个包放到单独一个文件夹里，然后使用rpm -ivh ./*来同时安装两个包，就能避免互相依赖的问题。
安装之后，就可以使用linux上编译nginx的方法来编译，简单来说，就是在源码文件夹下执行
./configue
检查编译环境，如果出现
bash-4.3# ./configure
checking for OS
+ AIX 1 00FA4D2E4C00
checking for C compiler ... not found
./configure: error: C compiler cc is not found
说明虽然安装了GCC，但是没有和CC建立关联，需要执行下面语句将CC软连接到GCC上
ln -s /opt/freeware/bin/gcc /usr/bin/cc
然后执行
make && make install
编译并安装，最后和linux一样，默认安装到/usr/local/nginx/bin/nginx
对于最近的几个版本，比如nginx 1.12.2和1.13.9，在make的时候都会遇见编译错误，如下
he.o src/core/ngx_open_file_cache.c
In file included from src/core/ngx_core.h:51:0,

^~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
make: The error code from the last command is 1.
Stop.
make: The error code from the last command is 2.
Stop.
在liunx上编译并不会出现这个问题，应该是编译器的配置不一样，因为AIX上的编译器把所有的Warning都当做Error来处理，所以出现一个Warning就会直接终止编译过程。但我们知道这并不是源码的问题，所以可以忽略Warning。方法是
找到 nginx-1.x.x/objs/Makefile 这个文件，在第二行有一个“-Werror”，需要将其改为“-Wno-error”
改之前
CC = cc
CFLAGS = -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g
CPP = cc -E
LINK = $(CC)
改之后
CC = cc
CFLAGS = -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Wno-error -g
CPP = cc -E
LINK = $(CC)
然后就可以顺利的编译了
