Posted 2022-01-12 冰原2010

（1）二进制安装mysql 5.7

1）下载MySQL包文件并解压：

[root@localhost ~]# tar xf mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz -C /usr/local
[root@localhost ~]# cd /usr/local/
[root@localhost local]# ln -sv mysql-5.7.33-linux-glibc2.12-x86_64 mysql

2）添加mysql用户：

[root@localhost ~]# groupadd mysql && useradd -r -g mysql mysql

3）数据库初始化：

[root@localhost local]# chown -R mysql:mysql /usr/local/mysql
[root@localhost local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

4）编写数据库配置文件：vim /etc/my.cnf

[mysqld]

datadir=/usr/local/mysql/data

basedir=/usr/local/mysql

socket=/var/lib/mysql/mysql.sock

port = 3306

user=mysql

# Disablingsymbolic-links is recommended to prevent assorted security risks

symbolic-links=0

[mysqld_safe]

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

pid-file=/var/run/mysqld/mysqld.pid

[client]

port=3306

socket=/var/lib/mysql/mysql.sock

5）准备服务文件：

[root@localhost local]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@localhost local]# chmod 755 /etc/init.d/mysqld
[root@localhost local]# chkconfig --add mysqld
[root@localhost local]# chkconfig mysqld on
[root@localhost local]# chkconfig --list

6）数据库启动：

[root@localhost local]# service mysqld start

7）添加环境变量：

[root@localhost local]# vim /etc/profile
        export PATH=$PATH:/usr/local/mysql/bin
        
[root@localhost local]# source /etc/profile

8）数据库安全配置：

[root@localhost local]# /usr/local/mysql/bin/mysql_secure_installation
