上代码

}Mysql权限处理
查看用户信息
select `Host`,`user` from user;
mysql> select `Host`,`user` from user;
+-----------+------------+
| Host | user |
+-----------+------------+
| 127.0.0.1 | root |
| ::1 | root |
| localhost | root |
+-----------+------------+
4 rows in set (0.00 sec)创建一个用户
示例：create user '用户名'@'host权限' identified by '密码';
mysql> create user 'test'@'%' identified by 'MV5vVQUu';
Query OK, 0 rows affected (0.00 sec)授予用户权限
示例：grant 权限类型(select、update、delete可多个，all 表示所有) privileges on 表名.操作权限(*表示所有) to '用户名'@'host权限'
mysql> grant all privileges on test_db.* to 'test'@'%';
Query OK, 0 rows affected (0.00 sec)查询用户权限
mysql> show grants for test@'%';
+-----------------------------------------------------------------------------------------------------------+
| Grants for test@% |
+-----------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'test'@'%' IDENTIFIED BY PASSWORD '*3EB9B6C888B00C67DA138D280D13B8C5129A1DD2' |
| GRANT ALL PRIVILEGES ON `test_db`.* TO 'test'@'%' |
+-----------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)取消用户权限
示例：revoke all on 表名.操作权限 from test@'%'
mysql> revoke all on test_db.* from test@'%';
Query OK, 0 rows affected (0.00 sec)再次查看用户权限
mysql> show grants for test@'%';
+-----------------------------------------------------------------------------------------------------------+
| Grants for test@% |
+-----------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'test'@'%' IDENTIFIED BY PASSWORD '*3EB9B6C888B00C67DA138D280D13B8C5129A1DD2' |
+-----------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
修改用户密码
//update 需要指定密码和password函数
//推荐方法
ALTER USER test@'%' IDENTIFIED BY '123456';最后别忘了刷新权限
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql>Linux中配置apache+php-fpm模式
先查找php-fpm.conf ,发现PHP的安装目录下没有该文件
在PHP安装目录下创建php-fpm配置文件，并输入以下内容（存在跳过此步骤）
[global]
pid = /www/server/php/70/var/run/php-fpm.pid
error_log = /www/logs/php/70/php-fpm.log
log_level = notice
[www]
listen = /tmp/php-cgi-70.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.status_path = /phpfpm_70_status
pm.max_children = 300
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 50
request_terminate_timeout = 100
request_slowlog_timeout = 30
slowlog = /www/logs/php/70/slow.log找到apache的配置文件，找到 php_module 项（代表你的PHP版本号）注释该项
再找到 mod_proxy.so 和 mod_proxy_fcgi.so 以及 mod_rewrite.so项，解除注释，启用模块
在apache配置文件中加载其它配置（比如网站域名配置）
IncludeOptional /www/server/apache/vhost/*.confphp-fpm模式5.png
创建测试文件
在web站点根目录下创建index.php
创建文件夹
mkdir /www/wwwroot/build创建文件
vim /www/wwwroot/build/index.php在文件中输入以下内容
phpinfo();保存退出#
创建apache的虚拟主机站点配置文件
在IncludeOptional 项指定的目录下创建一个任意文件名.conf的配置，我这里是index.conf
vim /www/server/apache/vhost/index.conf输入以下内容 (注意内容中的路径是可以自定义的)#
<VirtualHost *:80>
ServerAdmin webmaster@example.com
DocumentRoot "/www/wwwroot/build" #这里指定web的根目录
ServerName 192.168.1.3 #这里是web网站访问的域名
ServerAlias 192.168.1.3 #这里也是web网站访问的域名
errorDocument 404 /404.html
ErrorLog "/www/logs/www/1.error_log" #这里是web网站访问的日志
CustomLog "/www/logs/www/1.access_log" combined #这里是web网站访问的错误日志
#DENY FILES

SetOutputFilter DEFLATE
Options FollowSymLinks
AllowOverride All

</VirtualHost>修改所有新创建的文件所属权
重启apache
启动php-fpm
