本文實(shí)例講述了centos7環(huán)境下二進(jìn)制安裝包安裝 mysql5.6的方法。分享給大家供大家參考，具體如下：
centos7 二進(jìn)制安裝包安裝 mysql5.6
一、下載mysql5.6二進(jìn)制安裝包
http://mirrors.sohu.com/mysql/MySQL-5.6/
如:mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
二、安裝mysql5.6(安裝在/data/mysql56)
(1)、創(chuàng)建mysql用戶賬號(hào)
> useradd -s /sbin/nologin -M mysql
(2)、解壓壓縮包
> tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
(3)、重命名
> mv mysql-5.6.34-linux-glibc2.5-x86_64 mysql56
(4)、復(fù)制配置文件
> cp /data/mysql56/support-files/my-default.cnf /etc/my.cnf
修改配置文件
[client]
port = 3306
socket = /data/mysql56/mysql.sock
default-character-set = utf8
[mysqld]
skip-name-resolve
user = mysql
basedir = /data/mysql56
datadir = /data/mysql56/data
port = 3306
server_id = 10
socket = /data/mysql56/mysql.sock
pid-file = /data/mysql56/mysql.pid
log-error = /data/mysql56/data/mysql.err
log-bin = /data/mysql56/data/mysql-bin
character-set-server = utf8
(*二進(jìn)制安裝，默認(rèn)配置文件在/etc/my.cnf)
(5)、初始化數(shù)據(jù)庫(kù)
> chown -R mysql.mysql /data/mysq56
> /data/mysql56/scripts/mysql_install_db \
--defaults-file=/etc/my.cnf \
--user=mysql \
--basedir=/data/mysql56 \
--datadir=/data/mysql56/data
如果出現(xiàn)如下信息
FATAL ERROR: please install the following Perl modules before executing
Data::Dumper
> yum -y install autoconf
此包安裝時(shí)會(huì)安裝Data:Dumper模塊
三、配置并啟動(dòng)mysql
> cp /data/mysql56/support-files/mysql.server /etc/init.d/mysqld
> chmod 755 /etc/init.d/mysqld
(*注意,mysql二進(jìn)制安裝默認(rèn)的路徑為/usr/local/mysql,啟動(dòng)腳本里/usr/local/mysql需要替換)
> sed -i 's#/usr/local/mysql#/data/mysql56#g' /data/mysql56/bin/mysqld_safe /etc/init.d/mysqld
啟動(dòng)mysql
四、添加自啟動(dòng)
> chkconfig --add mysqld
> chkconfig mysqld on
> chkconfig --list mysqld
五、配置環(huán)境變量
> echo 'export PATH=/data/mysql56/bin:$PATH' >> /etc/profile
> source /etc/profile
六、修改mysql密碼(mysql5.6安裝默認(rèn)root密碼為空)
> mysqladmin -u root password '123456'
七、清理無(wú)用的mysql用戶及庫(kù)
登陸mysql
查詢用戶
> select user,host from mysql.user;
如下所示
+------+-----------------------+
| user | host |
+------+-----------------------+
| root | 127.0.0.1 |
| root | ::1 |
| | localhost |
| root | localhost |
| | localhost.localdomain |
| root | localhost.localdomain |
+------+-----------------------+
> drop user "root"@"::1";
> drop user ""@"localhost";
> drop user ""@"localhost.localdomain";
> drop user "root"@"localhost.localdomain";
刪除無(wú)用庫(kù)
