Mac为nginx安装nginx-sticky-module

nginx版本: nginx-1.9.8

下载

很多网站介绍sticky_module的来源和版本都不太一样，我尝试了下面来自于github上从google搬过去的1.0版本，和bitbucket.org的ng版本

https://github.com/lusis/nginx-sticky-module

.

https://bitbucket.org/nginx-goodies/nginx-sticky-module-ng

.
当然还有google版本

http://nginx-sticky-module.googlecode.com/files/nginx-sticky-module-1.1.tar.gz

目前共有2个版本，一个是1.0，一个是1.1，1.0已经寿终正寝了。1.1增加了权重的参数。

安装

先尝试github上clone的版本

* make 的时候会出现错误，可能是由于和我自己当前的nginx版本太高相关：

再尝试nginx.com上推荐的bitbucket.org版本

先clone

$ git clone https://bitbucket.org/nginx-goodies/nginx-sticky-module-ng.git

./configure将目标路径指向当前的nginx实例

$ ./configure --prefix=/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a --add-module=/Users/Richard/Documents/Dev/github/nginx-sticky-module-ng    

然后make && sudo make install

一切正常

...

test -d '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/logs'        || mkdir -p '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/logs'
test -d '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/logs' ||         mkdir -p '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/logs'
test -d '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/html'        || cp -R html '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a'
test -d '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/logs' ||         mkdir -p '/Users/Richard/Documents/Dev/servers/cluster/nginx/node-a/logs'   

结束
