centos7 安装nginx

1.解压

tar -xf nginx-1.10.1.tar.gz

2.配置

cd nginx-1.10.1

./configure --prefix=/data/my/nginx(注意这个目录是一个新目录，不是解压的源文件目录)

此时可能会提示

 

./configure: error: the HTTP rewrite module requires the PCRE library.

安装pcre-devel与openssl-devel解决问题

yum -y install pcre-devel openssl openssl-devel

 

./configure: error: C compiler cc is not found

yum -y install gcc gcc-c++ autoconf automake make

 

./configure: error: the HTTP rewrite module requires the PCRE library.

yum -y install pcre-devel

 

./configure: error: the HTTP gzip module requires the zlib library.

 yum install -y zlib-devel

 

 

然后继续

./configure --prefix=/data/my/nginx --with-http_ssl_module#如果不用https可以省掉后面这个参数

make

make install

 

安装完成后

cd /data/my/nginx/sbin

运行ng

./nginx

 

查看ng进程

ps -ef|grep nginx

查看80端口是否被ng占用lsof -i tcp:80

启动，停止,重载ng
./nginx 
./nginx -s stop
./nginx -s quit
./nginx -s reload

重启ng,先停止再启动（推荐）
./nginx -s quit
./nginx

 

在浏览器上试着访问http://ip:80，如不能访问，可能是防火墙的问题

firewall-cmd --state#查看防火墙状态
systemctl start firewalld.service#启动firewall
systemctl stop firewalld.service#停止firewall
systemctl disable firewalld.service#禁止firewall开机启动


 

如果开启了防火墙，要执行以下命令：

firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --zone=trusted --add-port=80/tcp

 

 开机启动

vi /lib/systemd/system/nginx.service

复制：

ExecStart=/usr/local/nginx/sbin/nginx

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

ExecStop=/usr/local/nginx/sbin/nginx -s quit

[Install]

保存完毕后

systemctl enable nginx.service
