Mac為nginx安裝nginx-sticky-module

---

nginx版本: nginx-1.9.8

nginx-sticky-module版本：nginx-sticky-module-ng

*注意產品環境請慎用!

參考來源:

Nginx模塊之SessionSticky

bitbucket.org

使用nginx sticky模塊實現基於cookie的負載均衡

NGINX 3rd Party Modules

下載

很多網站介紹sticky_module的來源和版本都不太一樣，我嘗試了下面來自於github上從google搬過去的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

.
當然還有google版本

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

目前共有2個版本，一個是1.0，一個是1.1，1.0已經壽終正寢了。1.1增加了權重的參數。

安裝

先嘗試github上clone的版本

* make 的時候會出現錯誤，可能是由於和我自己當前的nginx版本太高相關：

再嘗試nginx.com上推薦的bitbucket.org版本

先clone

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

./configure將目標路徑指向當前的nginx實例

$ ./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'
