| 服务器 | 软件版本 | 服务器地址 | 项目位置 |
|---|---|---|---|
| CentOS7 | 5.7.19 | X | /usr/local/program/mysql |
| 配置位置 | 数据位置 | 端口 | 账号/密码 |
|---|---|---|---|
| /etc/my.conf和/usr/local/program/mysql/my.conf | /data/mysql | 3306 | root/root |
##下载
##解压并改名
[root@localhost program]# tar zxf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz
[root@localhost program]# mv mysql-5.7.19-linux-glibc2.12-x86_64 mysql
##创建储存目录
[root@localhost program]# cd /data/
[root@localhost data]# ls
mongodb
[root@localhost data]# mkdir mysql
##创建角色组
[root@localhost data]# groupadd mysql
[root@localhost data]# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/program/mysql
[root@localhost data]# chown -R mysql .
[root@localhost data]# chgrp -R mysql .
[root@localhost data]# chown -R mysql /data/mysql
[root@localhost data]# chgrp -R mysql /data/mysql
[root@localhost data]# yum -y install numactl
##安装numactl避免后面的报错
##配置参数
[root@localhost data]# cd /usr/local/program/mysql
[root@localhost mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/program/mysql --datadir=/data/mysql/

##在mysql根目录下创建配置文件
[root@localhost mysql]# vim my.cnf

##修改启动文件
[root@localhost mysql]# vim ./support-files/mysql.server
basedir=/usr/local/program/mysql
datadir=/data/mysql
[root@localhost mysql]# cp ./support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# cp my.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
##设置权限
[root@localhost tmp]# cd /tmp/
[root@localhost tmp]# mkdir mysqld
[root@localhost tmp]# chown -R mysql mysqld
[root@localhost tmp]# chgrp -R mysql mysqld
##启动
[root@localhost tmp]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/data/mysql/localhost.localdomain.err'.
... SUCCESS!
##登录改配置
[root@localhost tmp]# cd /usr/local/program/mysql/bin/
[root@localhost bin]# ./mysql -uroot -p
Enter password: 8k?7*D!u#MQ= （这里是隐藏的）
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
####因为找不到错在哪，怀疑权限问题，所以把下面的话挨着执行了一遍
chown -R mysql /data/mysql
chgrp -R mysql /data/mysql
chown -R mysql /tmp
chgrp -R mysql /tmp
chown -R mysql /usr/local/program/mysql
chgrp -R mysql /usr/local/program/mysql
chown -R mysql /data/mysql .
chgrp -R mysql /data/mysql .
chown -R mysql /tmp .
chgrp -R mysql /tmp .
chown -R mysql /usr/local/program/mysql .
chgrp -R mysql /usr/local/program/mysql .
##然后 ojbk
[root@localhost bin]# service mysqld restart
Shutting down MySQL.. SUCCESS!
Starting MySQL.. SUCCESS!
[root@localhost bin]# ./mysql -uroot
