第一步：在centos下面下載 nginx
wget http://nginx.org/download/nginx-1.2.9.tar.gz
解壓 tar zxf nginx-1.2.9.tar.gz
第二部：新建一個用戶nginx在安裝操作
useradd nginx
passwd nginx
第三步、解壓和測試安裝環境 ./configure --prefix=/var/nginx
安裝過程中報錯
checking for OS
+ Linux 2.6.32-220.el6.x86_64 x86_64
checking for C compiler ... not found
./configure: error: C compiler gcc is not found
解決方法：安裝gcc
yum install 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=<path> option.
需要安裝
安裝pcre-devel解決問題 (root用戶下安裝)
yum -y install pcre-devel
繼續報錯誤
./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=<path> option.
需要安裝 yum install -y zlib-devel
在繼續執行 ./configure --prefix=/opt/nginx 安裝編譯成功
第四步：
make && make install
第五步：
cd /var/nginx/sbin
./nginx
如果報錯：
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
那說明80端口被占用，用命令netstat -ltunp查看一下是哪個服務占用了端口
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1547/mysqld
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 1247/vsftpd
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1233/sshd
tcp 0 0 :::80 :::* LISTEN 1258/httpd
tcp 0 0 :::22 :::* LISTEN 1233/ssh
可以看出需要把httpd服務關掉
service httpd stop
然后再運行./nginx就行了
然后打開瀏覽器輸入IP地址 顯示
Welcome to nginx!
