vi /etc/opt/remi/php56/php-fpm.d/www.conf

~~~
# user=apche, group=apache改成
user = nginx
group = nginx
~~~

vi /etc/nginx/default.d/default.conf
~~~
    ## enable php support ##
    location ~ \.php$ {
        root /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        include        fastcgi_params;

vi /usr/share/nginx/html/phpinfo.php

<?php
phpinfo();
~~~



systemctl enable php56-php-fpm.service
systemctl start php56-php-fpm


systemctl start nginx

# 打开浏览器
http://127.0.0.1/phpinfo.php






# 下面一大段 mysql 5.7
wget http://repo.mysql.com//mysql57-community-release-el7-7.noarch.rpm
rpm -Uvh mysql57-community-release-el7-7.noarch.rpm
yum install mysql-server
systemctl start mysqld

# 这一步查看到初始密码
grep "password" /var/log/mysqld.log

# 这一步输入刚才的初始密码
mysql -uroot -p
 
  # 以下语句在mysql的shell里执行，最后一句是设置密码
  set global validate_password_policy=0;
  set global validate_password_mixed_case_count=0;
  set global validate_password_number_count=3;
  set global validate_password_special_char_count=0;
  set global validate_password_length=3;
  SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123');

  # 下面这句话去除 mysql在yum仓库的记录，避免每次更新。
yum -y remove mysql57-community-release-el7-7.noarch 

# 这句话查看mysql的安装配置
# mysql_config
systemctl stop mysqld
systemctl start mysqld
