把mysql安装文件(除了data)的主人都改为root，避免数据库恢复为出厂设置。
shell># chown -R root /usr/local/mysql
shell># chown -R mysql /usr/local/mysql/data
& 后台运行mysql服务
shell># /usr/local/mysql/bin/mysqld_safe --user=mysql &
//查看mysql是否有启动
shell># ps –A | grep mysql
测试数据库
shell># /usr/local/mysql/bin/mysql –u root
mysql> show databases;
接上步,修改mysql密码(可不做此步,默认无密码)
mysql> UPDATE user SET Password=password('123456') WHERE user='root';
mysql> flush privileges;
配置开机自启动服务项
shell># cp 安装包解压目录/support-files/mysql.server /etc/init.d/mysqld
shell># chmod +x /etc/init.d/mysqld
shell># chkconfig --add mysqld
shell># chkconfig mysqld on //设置开机自启动
配置文件路径：
shell># vi /etc/rc.d/rc.local
在文件中增加启动相关服务的命令如下：
/usr/local/http2/bin/apachectl start
/usr/local/mysql/bin/mysqld_safe --user=mysql &
service vsftpd start
重新安装apache启动失败
[root@localhost httpd-2.2.19]# /usr/local/http2/bin/apachectl restart
httpd not running, trying to start
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
原因是80端口被占用
解决：
查看80端口使用情况
[root@localhost httpd-2.2.19]# netstat -lnp|grep 80
tcp 0 0 :::80 :::* LISTEN 28195/httpd
unix 2 [ ACC ] STREAM LISTENING 6580 1957/gpm /dev/gpmctl
unix 2 [ ACC ] STREAM LISTENING 5422 1800/pcscd /var/run/pcscd.comm
查看80的使用者是谁端口
[root@localhost httpd-2.2.19]# ps 28195
PID TTY STAT TIME COMMAND
28195 ? Ss 0:00 /usr/local/http2/bin/httpd -k restart
经过分析知道了80端口被系统的一个进程占用，这个进程是旧的apache服务
将这个进程杀之
[root@localhost httpd-2.2.19]# kill -9 28195
[root@localhost httpd-2.2.19]#
十一．卸载操作系统自带apache
删除默认apache进程
ps –A | grep http
杀死apache对应进程
killall httpd 杀死全部的httpd进程
把默认apache服务给删除
启动自己的apache
