mysql5.7版本二进制包安装方法

官网下载地址https://dev.mysql.com/downloads/mysql/5.7.html#downloads

系统环境CentOS6.8

一、添加mysql用户组及mysql用户

# groupadd mysql

# useradd -M -s /sbin/nologin mysql -g mysql

二、将二进制文件解压到指定的安装目录：/usr/local/mysql

# tar zxf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz  

 # mv mysql-5.7.24-linux-glibc2.12-x86_64 /usr/local/mysql

三、创建mysql数据存放的目录：/data/mysql

# mkdir -p /data/mysql 

四、更改所属的组和用户

# chown -R mysql:mysql /usr/local/mysql/

# chown -R mysql:mysql /data/mysql/

五、编辑参数文件

# vim /etc/my.cnf 

[client]
port = 3306
socket = /data/mysql/mysql.sock

[mysqld]
port = 3306
user = mysql
socket = /data/mysql/mysql.sock

basedir = /usr/local/mysql
datadir = /data/mysql
 

#以下设置utf8mb4字符集，可忽略
character-set-server = utf8mb4 
init_connect='SET NAMES utf8mb4'
default_storage_engine = innodb

#日志记录路径，需要mysql账户对其有写权限，先touch新建再更改所属组

log-error=/var/log/mysqld.log

六、初始化数据库

# cd /usr/local/mysql/

# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

[Note]部分为自动生成的password 

如果报错：./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

执行以下命令：

# yum -y install numactl

七、配置启动文件

# cp support-files/mysql.server /etc/init.d/mysqld

# chmod 755 /etc/init.d/mysqld

# chkconfig --add mysqld 

# chkconfig --list mysqld

mysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off

八、启动mysql服务

# service mysqld start

注：在/etc/profile中加入以下环境变量，可以用mysql代替/usr/local/mysql/bin/mysql启动

MYSQL_HOME=/usr/local/mysql 

export PATH=$PATH:$MYSQL_HOME/bin

设置后需要重新加载一下：

# source /etc/profile

九、初始化密码

#mysql -uroot -p‘xxxxx‘ #登陆MySQL客户端，密码为之前随机生成
mysql> SET PASSWORD=PASSWORD('root'); 
mysql> flush privileges;

想让root在其他客户端也能管理数据库：

执行 ： GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypassword' ; 

然后 执行：flush privileges; 
 

十、安全配置

# mysql_secure_installation
