centos系統LNMP環境配置（三） Nginx編譯安裝

安裝前提
1、安裝必備軟件

yum -y install zlib zlib-devel openssl openssl-devel

2、安裝pcre 支持nginx僞靜態（若已安裝直接跳過）

cd /usr/local/src
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.38.tar.gz
mkdir /usr/local/pcre                  // 創建安裝目錄
tar  zxvf pcre-8.30.tar.gz
cd pcre-8.30
./configure  --prefix=/usr/local/pcre  // 配置
make & make install

開始安裝Nginx
1、#添加www組和用戶,設置不允許www用戶直接登錄系統

[root@admin local]# groupadd  www  
[root@admin local]# useradd -g  www www -s /bin/false 

2、下載源碼

 [root@admin local]# cd /usr/local/src 
 [root@admin local]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
 [root@admin local]# tar -zxvf nginx-1.6.2.tar.gz
 [root@admin local]# cd nginx-1.6.2/

3、創建安裝路徑

[root@admin local]# mkdir /usr/local/nginx

4、安裝

[root@admin nginx]# ./configure --prefix=/usr/local/nginx
[root@admin nginx]# make & make install

配置Nginx自啓動腳本

1、將啓動腳本保存至/etc/init.d/nginx 文件中
2、設置腳本啓動權限

[root@admin nginx]# chmod +x /etc/init.d/nginx

3、執行nginx命令

/etc/init.d/nginx start 或 service nginx start   //啓動
/etc/init.d/nginx stop 或 service nginx stop    //關閉nginx
/etc/init.d/nginx restart 或 service nginx restart  //重啓nginx

配置開機自動啓動

chkconfig --add nginx
chkconfig --level 2345 nginx on
