CentOS7 安装 Nginx

YUM 安装

1.下载nginx包

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

2.建立nginx的yum仓库

rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

3.下载并安装nignx

yum install nginx

4.启动nginx服务

systemctl start nginx

5.如果在浏览器中输入部署nginx环境的IP不能访问，可能是端口没有开启

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

重启防火墙

systemctl stop firewalld.service   
systemctl start firewalld.service

命令含义：

--zone #作用域

--add-port=80/tcp #添加端口，格式为：端口/通讯协议

--permanent #永久生效，没有此参数重启后失效

源码编译安装

下载 Nginx 安装包

访问 Nginx 下载页面，这里下载固定版本：wget http://nginx.org/download/nginx-1.14.2.tar.gz。

检查是否已经YUM安装

如果已安装，使用 yum remove nginx 命令删除。

➜  ~ yum list installed | grep nginx

安装 Nginx

# 解压缩
➜  tar -xvf nginx-1.14.2.tar.gz
# 进入解压后的文件夹
➜  cd nginx-1.14.2
# 检查环境依赖，最后会提供如下的配置信息
➜  ./configure
# 编译安装
➜  make && make install

./configure 执行后提示的 nginx 配置信息：

nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx modules path: "/usr/local/nginx/modules"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"

运行 Nginx

/usr/local/nginx 中包含四个主要的目录：

conf：配置文件
html：默认的 nginx 访问路径
logs：各种日志信息
sbin：二进制启动脚本

# 运行 nginx
/usr/local/nginx/sbin/nginx
# 查看运行进程
ps -ef | grep nginx
