如何在 CentOS 6 上將 nginx 從 1.6.3 升級到 1.8.x

Question

我在 CentOS 6，nginx 1.6.3

$nginx -v
nginx version: nginx/1.6.3

我想將 nginx 升級到 1.8 因為add_header [always] 指令需要

我正在關注https://webtatic.com/packages/nginx18/進行升級但出現以下錯誤

$yum list nginx*
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
 * base: mirrors.service.networklayer.com
 * epel: free.nchc.org.tw
 * extras: mirrors.service.networklayer.com
 * updates: mirrors.service.networklayer.com
 * webtatic: uk.repo.webtatic.com
Installed Packages
nginx16.x86_64       1.6.3-1.w6       @webtatic
Available Packages
nginx18.x86_64       1.8.0-1.w6       webtatic

當我跑步時yum install -y nginx18，它給出

Transaction Check Error:
  file /usr/sbin/nginx from install of nginx18-1.8.0-1.w6.x86_64 conflicts with file from package nginx16-1.6.3-1.w6.x86_64

Error Summary

有人可以指導我在 CentOS 6 上完成將 nginx 從 1.6.3 升級到 1.8 的正確步驟嗎？理想情況下，不要yum remove-ing nginx16 然後安裝 nginx18，這會導致伺服器停機。

Answer 1

由於 nginx 軟體包並沒有設計為同時安裝多個版本，因此您需要卸載舊版本並安裝新版本：

$ yum remove nginx16
$ yum install nginx18

或者，您可以嘗試

 $ yum install yum-plugin-replace
 $ yum replace nginx16 --replace-with=nginx18
 $ service nginx restart

但最好先在測試伺服器上進行測試。
