linux下安装lnmp环境

1.安装nginx
yum install yum-priorities -y
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum install nginx
systemctl start nginx.service #启动nginx
systemctl stop nginx.service #停止
systemctl restart nginx.service #重启
systemctl enable nginx.service #设置开机启动

2.更改nginx端口号（根据自己需求）
cd /etc/nginx/conf.d/
vim default.conf
把listen 80改成listen 81
systemctl restart nginx.service #重启nginx

3.访问http://ip:81即可看到nginx首页

4.下一步安装php-fpm
yum install php-fpm
systemctl start php-fpm.service #启动php-fpm
systemctl enable php-fpm.service #设置开机启动

5.更改nginx配置文件识别php
vi /etc/nginx/conf.d/default.conf，把之前的#给去掉就可以了，顺手改一下fastcgi_param
location ~ \.php$ {
root           html;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;
include        fastcgi_params;
}

6.
在 /usr/share/nginx/html中新建一个test.php  <?php echo 123;?>
访问http://ip:81/test.php即可看到nginx中的php页面

7.负载配置
upstream site{
server 172.16.170.138;
server 172.16.170.139;
}
server {
listen       80;
server_name  localhost;

#charset koi8-r;
#access_log  /var/log/nginx/log/host.access.log  main;

location / {
root   /usr/share/nginx/html;
index  index.html index.htm;
proxy_pass http://site; }
安装两个服务器只需改下端口号即可

文件夹目录显示
/etc/nginx/nginx.conf
在nginx.conf文件中的http 里加入
autoindex on;# 显示目录
autoindex_exact_size on;# 显示文件大小
autoindex_localtime on;# 显示文件时间
