nginx在linux下安装

1. 安装前先确认是否已经安装编译包和一些依赖包如果没有安装：

yum install pcre*

yum install openssl*

yum install zlib

yum install zlib-devel

yum install wget

查看是否已经安装好 rpm -qa | grep "查看的内容"

2.开始安装nginx

wget http://nginx.org/download/nginx-1.8.0.tar.gz

3. 解压

如果你想把安装包复制到别处 可以  cp nginx-1.8.0.tar.gz  路径（例如/usr/local）

tar -zxvf nginx-1.8.0.tar.gz

4.解压完毕开始安装

cd  nginx-1.8.0

./configure --prefix=/opt/nginx --with-http_stub_status_module // --prefix=/opt/nginx  这个是指定安装路径

5.启动nginx 我这里安装在了opt/nginx

cd /opt/nginx

./nginx //如果执行此步骤时出现端口被占用 ：

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

我这里是80端口被占用了查看哪些占用了80端口

fuser -n tcp 80

返回消息是80/tcp:              12965 12966

然后通过 kill -9 删除进程

kill -9 12965

kill -9 12966

然后再启动nginx

./nginx
