centos7安装nginx

centos7安装nginx有两种方式，这里重点介绍源码包安装

yum安装

添加nginx到yum源中

1
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

安装nginx

1
yum install -y nginx

启动nginx

1
systemctl start nginx

设置开机自启

1
systemctl enable nginx

源码包安装

首先安装依赖包
安装gcc

1
yum install -y gcc-c++

安装pcre

1
yum install -y pcre pcre-devel

安装zlib

1
yum install -y zlib zlib-devel

安装openssl

1
yum install -y opsenssl openssl-devel

下载安装nginx
首先到官网：nginx下载链接

下载安装包上传至/usr/local/nginx.这个目录是软件默认安装路径，然后解压缩

1
tar -zxvf nginx-1.20.2.tar.gz  

或者直接在线下载

1
2

4
mkdir /usr/local/nginx
cd /usr/local/nginx
yum install -y wget
wget http://nginx.org/download/nginx-1.20.2.tar.gz

解压缩

1
tar zxvf nginx-1.20.2.tar.gz

进入nginx目录下

1
cd nginx-1.20.2

检查平台安装环境

1
./configure --prefix=/usr/local/nginx

编译并安装

1
2
make
make install

启动nginx

1
/usr/local/nginx/sbin/nginx

防火墙开放80端口

1
firewall-cmd --zone=public --add-port=80/tcp --permanent

重启防火墙

1
firewall-cmd --reload

看到下面的界面就说明成功了

设置开机启动

因为是用源码编译安装的，所以首先需要手动将nginx添加至服务

1
vi /etc/init.d/nginx
