[root@localhost Desktop]$ rpm -qa | grep mysql mysql-libs-5.1.52-1.el6_0.1.x86_64 [root@localhost ~]# rpm -e mysql-libs-5.1.52.x86_64 --nodeps [root@localhost ~]#
3.创建mysql用户及组
[root@localhost ~]#groupadd mysql
[root@localhost ~]#useradd -r -g mysql mysql
之后可以查看一下成功创建没
[root@localhost ~]# cat /etc/group | grep mysql
[root@localhost ~]# cat /etc/passwd | grep mysql4.
[root@promote local]# tar -zxvf mysql-5.7.15-linux-glibc2.5-i686.tar.gz
5. 解压成功后将文件改个名字
[root@promote local]# mv mysql-5.7.15-linux-glibc2.5-i686 mysql
6.安装和初始化数据库
[root@promote local]# mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
[root@promote local]# cd mysql
[root@promote local]#
[root@promote mysql]#cp -a ./support-files/my-default.cnf /etc/my.cnf
问你是否覆盖时，yes
[root@promote local]#cp -a ./support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# cd bin/
[root@localhost bin]# ./mysqld_safe --user=mysql &
[1] 1986

mysql> use mysql; mysql> update user set host = ‘%‘ where user = ‘root‘; mysql>quit [root@promote bin]# /etc/init.d/mysqld restart
9.开放端口3306（也可以用其他端口）
[root@localhost bin]#/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT;
[root@localhost bin]#/etc/init.d/iptables status
[root@localhost bin]#/etc/rc.d/init.d/iptables save
