## 1.重启数据库 ##

**\[root@localhost init.d\]\# /etc/init.d/mysqld restart**  
 ERROR! MySQL server PID file could not be found!  
Starting MySQL.. ERROR! The server quit without updating PID file (/var/lib/mysql/data/localhost.localdomain.pid).

**启动失败，因为缺少pid文件。各种方法试过后行不通，于是初始化数据库试试。**

**\[root@localhost ~\]\# /var/lib/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/var/lib/mysql --datadir=/var/lib/mysql/data**  
2018-07-30T12:56:56.410138Z 0 \[Warning\] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit\_defaults\_for\_timestamp server option (see documentation for more details).  
2018-07-30T12:56:56.412372Z 0 \[ERROR\] --initialize specified but the data directory has files in it. Aborting.  
2018-07-30T12:56:56.412409Z 0 \[ERROR\] Aborting

**提示数据目录已经创建，于是将其备份移除，再次初始化。**

**执行成功。**

**\[root@localhost mysql\]\# /etc/init.d/mysqld start**  
Starting MySQL. SUCCESS!

## 2.apache安装Discuz ##

**查看apache错误日志**

\[Mon Jul 30 21:13:56.715161 2018\] \[php7:error\] \[pid 28848:tid 140433527129856\] \[client ----------\] PHP Fatal error:  U      ncaught Error: Call to undefined function set\_magic\_quotes\_runtime() in /usr/local/apache/htdocs/upload/install/index.php:12\\nS      tack trace:\\n\#0 \{main\}\\n  thrown in /usr/local/apache/htdocs/upload/install/index.php on line 12, referer: http://192.168.0.21/

**试着把安装目录下的index.php文件line 12 注释掉，可以安装**

## 3.连接数据库 ##

**安装完成之后，显示如图**

![70 2][]

**显示无连接，应该是数据库的问题了，检查日志一切正常，看到个帖子说mysql -u 可以直接登录，试了下，果真。**

搜索了几个网上的答复：

**检查mysql扩展是否安装**

**mysql连接数不够**

更改主机名：[https://blog.csdn.net/leedaning/article/details/46380097][https_blog.csdn.net_leedaning_article_details_46380097]

**试了以上方法，都行不通。于是将源码编译的mysql删除，重新安装，又提示报错。**

**百度说是php7不支持mysql扩展，于是再删除php，换个低版本的安装。**
