1.yum安装最新版Nginx源

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

安装Nginx

yum install -y nginx

Nginx默认目录

whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx

以下是Nginx的默认路径：

(1) Nginx配置路径：/etc/nginx/
(2) PID目录：/var/run/nginx.pid
(3) 错误日志：/var/log/nginx/error.log
(4) 访问日志：/var/log/nginx/access.log
(5) 默认站点目录：/usr/share/nginx/html

事实上，只需知道Nginx配置路径，其他路径均可在/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf 中查询到。

常用命令

(1) 启动：
nginx
(2) 测试Nginx配置是否正确：
nginx -t
(3) 优雅重启：
nginx -s reload
(4) 停止：
nginx -s stop

2. centos7.5 1804 编译安装nginx方法

安装依赖软件包集合

yum install openssl openssl-devel pcre pcre-devel -y
rpm -qa openssl openssl-devel pcre pcre-devel

安装nginx软件包命令集合

mkdir -p /application /tools
cd /tools
wget -q http://nginx.org/download/nginx-1.16.0.tar.gz
tar -zxvf nginx-1.16.0.tar.gz
useradd -s /sbin/nologin -M nginx                       
cd nginx-1.16.0
./configure --user=nginx --group=nginx --prefix=/application/nginx-1.16.0 --with-http_ssl_module  --with-http_stub_status_module --with-http_flv_module --http-fastcgi-temp-path=/application/nginx-1.16.0/nginx/fcgi

make
make install
ln -s /application/nginx-1.16.0 /application/nginx
#设置配置文件
cd /application/nginx/conf
cp nginx.conf nginx.conf.bak
egrep -v "#|^$" nginx.conf.bak >nginx.conf                #去除#号开头和空行
#启动nginx
/application/nginx/sbin/nginx -t                          #有报错  mkdir nginx/fcgi
/application/nginx/sbin/nginx                             #启动完成80端口可以访问

• nginx安装完成
• 附录 nginx.conf基础配置文件
