CentOS 7 yum 安装 Nginx

阅读数:0次 2018-09-14

1.添加Nginx到YUM源

添加CentOS 7 Nginx yum资源库,打开终端,使用以下命令:

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

2.安装Nginx

在你的CentOS 7 服务器中使用yum命令从Nginx源服务器中获取来安装Nginx：

1	sudo yum install -y nginx

3.启动Nginx

刚安装的Nginx不会自行启动。运行Nginx:

1	sudo systemctl start nginx.service

这时就可以通过ip正常访问默认页面了。

更多Nginx配置信息

//列出nginx的安装文件，快速定位配置文件目录
rpm -ql nginx 

//网站文件存放默认目录
/usr/share/nginx/html

//网站默认站点配置
/etc/nginx/conf.d/default.conf

//自定义Nginx站点配置文件存放目录
/etc/nginx/conf.d/

//Nginx全局配置
/etc/nginx/nginx.conf

//Nginx启动
nginx -c nginx.conf

//Linux查看公网IP
ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

//检查配置文件ngnix.conf的正确性命令：
/usr/sbin/nginx -t

QUESTIONS

Nginx: [error] open() ＂/usr/local/Nginx/logs/Nginx.pid

1	/usr/sbin/nginx -c /etc/nginx/nginx.conf

参考配置

创建 Nginx 运行使用的用户 www：(不用www可能会报错)

1 2	[root@bogon conf]# /usr/sbin/groupadd -f www [root@bogon conf]# /usr/sbin/useradd -g www www

配置nginx.conf ，将/usr/sbin/nginx.conf替换为以下内容

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
