这篇文章将为大家详细讲解有关linux php安装mysql数据库的方法,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
linux php安装mysql数据库的方法:首先关闭linux的防火墙;然后从mysql官网上下载自己适合的mysql版本;接着在mysql当前目录下设定目录的访问权限;最后查看mysql状态即可。
1、首先关闭linux的防火墙,执行命令
chkconfig iptables off
2、
从mysql官网上下载自己适合的mysql版本
https://dev.mysql.com/downloads/mysql/5.6.html#downloads,进入mysql官网,依次点击
3、下载后的mysql文件
mysql-5.6.40-linux-glibc2.12-i686.tar.gz
将下载好的mysql压缩文件放置在linux的/usr/local文件夹下,解压该压缩文件
tar -zxvf mysql-5.6.40-linux-glibc2.12-i686.tar.gz
将解压后的文件重命名为mysql
mv mysql-5.6.40-linux-glibc2.12-i686 mysql
4、创建mysql用户组及用户
groupadd mysql useradd -r -g mysql mysql
5、进入到mysql目录,执行添加MySQL配置的操作
cp support-files/my-medium.cnf /etc/my.cnf 或: cp support-files/my-default.cnf /etc/my.cnf
是否覆盖?按y 回车
6、编辑/etc/my.cnf文件;
vi /etc/my.cnf
在my.cnf文件中添加或者修改相关配置,更改完成后保存退出

7、在mysql当前目录下设定目录的访问权限(注意后面的小点,表示当前目录)
chown -R mysql . chgrp -R mysql . scripts/mysql_install_db --user=mysql chown -R root . chown -R mysql data
8、初始化数据(在mysql/bin或者mysql/scripts下有个 mysql_install_db 可执行文件初始化数据库),进入mysql/bin或者mysql/scripts目录下,执行下面命令
./mysql_install_db --verbose --user=root --defaults-file=/etc/my.cnf --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp
9、启动mysql,进入/usr/local/mysql/bin目录,执行下面命令
./mysqld_safe --defaults-file=/etc/my.cnf --socket=/tmp/mysql.sock --user=root &
注意,如果光标停留在屏幕上,表示启动成功,需要我们先关闭shell终端,再开启一个新的shell终端,不要执行退出操作。如果出现 mysql ended这样的语句,表示Mysql没有正常启动,你可以到log中查找问题.
10、设置开机启动,新开启shell中断后,进入mysql目录,执行下面命令
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
chmod 700 /etc/init.d/mysql chkconfig --add mysqld chkconfig --level 2345 mysqld on chown mysql:mysql -R /usr/local/mysql/
重启linux
reboot
查看mysql状态
service mysqld status
11、添加远程访问权限
(1)、添加mysql命令
ln -s /usr/local/mysql/bin/mysql /usr/bin (mysql的安装路径)
(2)、更改访问权限
登录mysql,执行下面命令 mysql -uroot -p 密码为空直接回车,运行以下两条命令 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'duan' with grant option; Flush privileges;
退出mysql
exit
重启linux,就完成了
reboot
注:本机访问mysql,root账户默认是没有密码的,端口号默认3306,如果需要修改root账户密码,在/usr/local/mysql/bin目录下,执行下面命令
./mysqladmin -h 127.0.0.1 -P3306 -uroot password 'duan'exit
