因为服务器月底要到期，刚好阿里云双十一有活动，续费8折、新购5折，加上前段时间的优惠券，新购的话能比续费便宜近2000，所以新买了一台。

月底到期后就要把网站迁移过来了，首先得先在新服务器上安装lnmp环境。（好兴奋😝）

一、首先是nginx的安装

首先更新一下nginx的rpm源

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

然后安装nginx

# yum -y install nginx

安装完成后查看nginx版本 nginx -v

nginx version: nginx/1.12.2

最新版1.12.2没问题

然后设置nginx开机启动

# systemctl enable nginx

输出结果

Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

然后启动nginx，并查看nginx的状态

# systemctl start nginx        
# systemctl status nginx

输出如下

● nginx.service - nginx - high performance web server        
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)        
   Active: active (running) since Fri 2017-11-10 13:08:59 CST; 11s ago        
     Docs: http://nginx.org/en/docs/        
  Process: 1477 ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf (code=exited, status=0/SUCCESS)        
  Process: 1475 ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf (code=exited, status=0/SUCCESS)        
 Main PID: 1479 (nginx)        
   CGroup: /system.slice/nginx.service        
           ├─1479 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf        
           └─1480 nginx: worker process        

Nov 10 13:08:59 iz2zebopxrlqc8he1kgzrjz systemd[1]: Starting nginx - high performance web server...        
Nov 10 13:08:59 iz2zebopxrlqc8he1kgzrjz nginx[1475]: nginx: the configuration file /etc/nginx/nginx.conf syntax is ok        
Nov 10 13:08:59 iz2zebopxrlqc8he1kgzrjz nginx[1475]: nginx: configuration file /etc/nginx/nginx.conf test is successful        
Nov 10 13:08:59 iz2zebopxrlqc8he1kgzrjz systemd[1]: Started nginx - high performance web server.

看起来没问题。正常跑起来了。

二、接下来是MySQL的安装

还是先更新一下MySQL的rpm源

https://dev.mysql.com/downloads/repo/yum/

# rpm -Uvh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

然后安装mysql

# yum -y install mysql-community-server mysql-community-devel

# grep socket /etc/my.cnf        
socket=/var/lib/mysql/mysql.sock

然后查看mysql状态

# systemctl status mysqld        
● mysqld.service - MySQL Server        
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)        
   Active: inactive (dead)        
     Docs: man:mysqld(8)        
           http://dev.mysql.com/doc/refman/en/using-systemd.html

设置mysql开启启动

# systemctl enable mysqld

启动mysql

# systemctl start mysqld

新版MySQL会随机生成一个root密码，查看Mysql密码

# grep 'temporary password' /var/log/mysqld.log        
2017-11-10T05:49:48.997304Z 1 [Note] A temporary password is generated for root@localhost: SZ?8JjG8Z-#y

SZ?8JjG8Z-#y就是随机密码，现在要做的是使用这个密码修改一下密码

# mysql -uroot -p        
mysql&gt; ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxx';

允许远程登录

mysql&gt; update mysql.user set Host='%' where HOST='localhost' and User='root'        
mysql&gt; quit

三、然后是安装php7

首先安装php依赖

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel curl curl-devel openssl openssl-devel

下载php包

http://www.php.net/downloads.php

# wget http://cn2.php.net/distributions/php-7.1.11.tar.gz

解压

# tar zxf php-7.1.11.tar.gz         
# cd php-7.1.11        
# ./configure --prefix=/usr/local/php7 --enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --with-mysqli --with-zlib --with-curl --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-openssl --enable-mbstring --enable-xml --enable-session --enable-ftp --enable-pdo -enable-tokenizer --enable-zip

如果configure成功应该能看到下面的字样

+--------------------------------------------------------------------+

+--------------------------------------------------------------------+        

Thank you for using PHP.

然后执行安装

# make &amp;&amp;  make install

这个过长很漫长

完成之后配置php.ini

# cp php.ini-development /usr/local/php7/lib/php.ini

需要配置下mysql.sock

 mysqli.default_socket = /var/lib/mysql/mysql.sock

时区设置

 date.timezone = Asia/Shanghai

然后保存退出，查看下php的版本

# /usr/local/php7/bin/php -v        
PHP 7.1.11 (cli) (built: Nov 10 2017 14:41:31) ( NTS )        
Copyright (c) 1997-2017 The PHP Group        
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

接下来配置 php-fpm

# cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf        
# cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

配置 php-fpm 启动脚本

# cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/

重新载入 systemd

# systemctl daemon-reload

设置php-fpm开机启动

# systemctl enable php-fpm

启动

# systemctl start php-fpm

查看状态

# systemctl status php-fpm        
● php-fpm.service - The PHP FastCGI Process Manager        
   Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; enabled; vendor preset: disabled)        
   Active: active (running) since Fri 2017-11-10 15:41:23 CST; 3s ago        
 Main PID: 13486 (php-fpm)        
   CGroup: /system.slice/php-fpm.service        
           ├─13486 php-fpm: master process (/usr/local/php7/etc/php-fpm.conf)        
           ├─13487 php-fpm: pool www        
           └─13488 php-fpm: pool www        

Nov 10 15:41:23 iz2zebopxrlqc8he1kgzrjz systemd[1]: Started The PHP FastCGI Process Manager.        
Nov 10 15:41:23 iz2zebopxrlqc8he1kgzrjz systemd[1]: Starting The PHP FastCGI Process Manager...

active表示成功启动了。

然后测试一下是否安装成功

# mkdir /home/www/html        
# cd /home/www/html        
# vi test.php

输入下面的内容

phpinfo();

然后创建一个nginx站点的配置文件

# cd /etc/nginx/conf.d/

新建一个人配置文件test.com.conf并写入下面的内容

server {        
    listen       80;        
    server_name  localhost;        
    root         /home/www/html;        
    location / {        
        index  index.php index.html index.htm;        
    }        
    location ~ \.php$ {        
        fastcgi_pass   127.0.0.1:9000;        
        fastcgi_index  index.php;        
    fastcgi_param    SCRIPT_FILENAME    $document_root$fastcgi_script_name;        
    fastcgi_param  PHP_VALUE        open_basedir=$document_root:/tmp/:/proc/;        
        include        fastcgi_params;        
    }        
}

重启nginx使配置生效
