一、环境确认
1、确认网络可用
登录服务器后执行：ping www.baidu.com
2、确认yum可用
yum list|grep nginx
3、确认关闭iptables规则
查看是否开启
iptables -L
关闭
iptables -F
iptables -t nat -F
Centos7永久关闭防火墙
启动一个服务：systemctl start firewalld.service
关闭一个服务：systemctl stop firewalld.service
重启一个服务：systemctl restart firewalld.service
显示一个服务的状态：systemctl status firewalld.service
在开机时启用一个服务：systemctl enable firewalld.service
在开机时禁用一个服务：systemctl disable firewalld.service
查看服务是否开机启动：systemctl is-enabled firewalld.service
查看已启动的服务列表：systemctl list-unit-files|grep enabled
4、确认停用selinux
查看
getenforce
关闭
setenforce 0
永久关闭方法
vim /etc/sysconfig/selinux
reboot
重启后即永久关闭
5、安装对应的工具
yum -y install gcc gcc-c++ autoconf pcre pcre-devel make automake
yum -y install wget httpd-tools vim
6、创建对应的目录
cd /opt
mkdir app download logs work backup
app:存放代码 download:存放下载的代码或程序包 logs:日志
7、安装Nginx
打开官网：http://nginx.org/
即
Pre-Built Packages for Stable version
To set up the yum repository for RHEL/CentOS, create the file named /etc/yum.repos.d/nginx.repo with the following contents:
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “6” or “7”, for 6.x or 7.x versions, respectively.
For Debian/Ubuntu, in order to authenticate the nginx repository signature and to eliminate warnings about missing PGP key during installation of the nginx package, it is necessary to add the key used to sign the nginx packages and repository to the apt program keyring. Please downloadthis key from our web site, and add it to the apt program keyring with the following command:
sudo apt-key add nginx_signing.key
For Debian replace codename with Debian distribution codename, and append the following to the end of the /etc/apt/sources.list file:
deb http://nginx.org/packages/debian/codenamenginxdeb-src http://nginx.org/packages/debian/codenamenginx
For Ubuntu replace codename with Ubuntu distribution codename, and append the following to the end of the /etc/apt/sources.list file:
deb http://nginx.org/packages/ubuntu/codenamenginxdeb-src http://nginx.org/packages/ubuntu/codenamenginx
For Debian/Ubuntu then run the following commands:
apt-get update
apt-get install nginx
For SLES run the following command:
zypper addrepo -G -t yum -c 'http://nginx.org/packages/sles/12' nginx
输入命令：
vim /etc/yum.repos.d/nginx.repo
修改好：
查看：
安装：
yum -y install nginx
查看是否安装成功
nginx -v
查看Nginx都安装了哪些目录
命令：rpm -ql nginx
Nginx安装完成如果要换成/data/www的根目录
若报FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream
将fastcgi_param对应的
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
换成
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
