CentOS7安裝Nginx并配置自動啟動實例分析

1、官網下載安裝包

選擇適合linux的版本,這里選擇最新的版本,下載到本地后上傳到服務器或者centos下直接wget命令下載。

切換到/usr/local目錄,下載軟件包

#?cd?/usr/local #?wget?http://nginx.org/download/nginx-1.11.5.tar.gz

2、安裝nginx

先執行以下命令,安裝nginx依賴庫,如果缺少依賴庫,可能會安裝失敗,具體可以參考文章后面的錯誤提示信息。

#?yum?install?gcc-c++ #?yum?install?pcre #?yum?install?pcre-devel #?yum?install?zlib? #?yum?install?zlib-devel #?yum?install?openssl #?yum?install?openssl-devel

解壓安裝包

#?tar?-zxvf?nginx-1.11.5.tar.gz

nginx被解壓到了/usr/local/nginx-1.11.5 目錄下(不要把壓縮包解壓到/usr/local/nginx目錄下,或者將解壓后的目錄重命名為nginx,因為nginx會默認安裝到/usr/local/nginx目錄下),切換到nginx-1.11.5/目錄

#?cd?/usr/local/nginx-1.11.5/

執行# ./configure

#?./configure

該操作會檢測當前系統環境,以確保能成功安裝nginx,執行該操作后可能會出現以下幾種提示:

????checking for os

?????+ linux 3.10.0-123.el7.x86_64 x86_64

????checking for c compiler … not found

????./configure: error: c compiler cc is not found

????如果出現以上錯誤提示信息,執行yum install gcc-c++安裝gcc,

????./configure: error: the http rewrite module requires the pcre library.

????you can either disable the module by using –without-http_rewrite_module

????option, or install the pcre library into the system, or build the pcre library

????statically from the source with nginx by using –with-pcre= option.

????如果出現上面提示,表示缺少pcre庫

????./configure: error: the http gzip module requires the zlib library.

????you can either disable the module by using –without-http_gzip_module

????option, or install the zlib library into the system, or build the zlib library

????statically from the source with nginx by using –with-zlib= option.

????如果出現以上提示,表示缺少zlib庫

?如果沒有出現./configure: error提示,表示當前環境可以安裝nginx,執行make和make install編譯nginx

#?make #?make?install

沒有出錯的話,表示nginx已經成功安裝完成,默認安裝位置為/usr/local/nginx,之前的/usr/local/nginx-1.11.5/可以刪除掉了。

如果出現cp: ‘conf/koi-win’ and ‘/usr/local/nginx/conf/koi-win’ are the same file,可能是你把安裝包解壓到了/usr/local/nginx目錄,解決辦法是將該目錄重命名為其他名稱后再執行make,make install.

3、配置nginx開機啟動

切換到/lib/systemd/system/目錄,創建nginx.service文件vim nginx.service

#?cd?/lib/systemd/system/ #?vim?nginx.service

文件內容如下:

[unit] description=nginx? after=network.target? ? [service]? type=forking? execstart=/usr/local/nginx/sbin/nginx execreload=/usr/local/nginx/sbin/nginx?reload execstop=/usr/local/nginx/sbin/nginx?quit privatetmp=true? ? [install]? wantedby=multi-user.target

退出并保存文件,執行systemctl enable nginx.service使nginx開機啟動

#?systemctl?enable?nginx.service

systemctl start nginx.service????啟動nginx

systemctl stop nginx.service????結束nginx

systemctl restart nginx.service????重啟nginx

4、驗證是否安裝成功

輸入http://服務器ip/?如果能看到nginx的界面,就表示安裝成功了
