centos下安装nginx

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

#   find -name nginx

$   yum remove nginx

$   cd /usr/local

$   wget http://nginx.org/download/nginx-1.7.4.tar.gz[/code] 
解压nginx压缩包

$   tar -zxvf nginx-1.7.4.tar.gz


会产生一个nginx-1.7.4 目录，这时进入nginx-1.7.4目录

$   cd  nginx-1.7.4


接下来安装，使用–prefix参数指定nginx安装的目录,make、make install安装

$   ./configure  $默认安装在/usr/local/nginx
$   make
$   make install


如果没有报错，顺利完成后，最好看一下nginx的安装目录

$   whereis nginx


重启nginx

/usr/local/nginx/sbin/nginx -s reload


如果报错：nginx: [error] open() “/usr/local/nginx/logs/nginx.pid” failed (2: No such file or directory)

解决办法：

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf


如果报错：[emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

解决办法：

sudo fuser -k 80/tcp


ok！
