mysql进阶

mysql进阶

  • 1.下载二进制格式的mysql软件包
[root@mr ~]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz
[root@mr ~]# cd /usr/src/
[root@mr src]# ls
debug  kernels  mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz
[root@mr src]#

  • 2.创建用户和组,解压软件至/usr/local/,修改目录/usr/local/mysql的属主属组
[root@mr src]# id mysql
id: 'mysql': no such user
[root@mr src]# useradd -M -r -s /sbin/nologin mysql
[root@mr src]# id mysql
uid=993(mysql) gid=990(mysql) groups=990(mysql)
[root@mr src]# tar xf mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
[root@mr src]# cd /usr/local/
[root@mr local]# ll

1. 添加环境变量

[root@mr ~]# cd /usr/local/mysql
[root@mr mysql]# ls
bin  docs  include  lib  LICENSE  man  README  share  support-files
[root@mr mysql]# cd bin/
[root@mr bin]# pwd
/usr/local/mysql/bin
[root@mr bin]# echo 'export PATH=$PATH:/usr/local/mysql/bin' > /etc/profile.d/mysql.sh
[root@mr bin]# source /etc/profile.d/mysql.sh
[root@mr bin]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/mysql/bin
[root@mr bin]# which mysql
/usr/local/mysql/bin/mysql
[root@mr bin]#
[root@mr mysql]# ln -sv /usr/local/mysql/include/ /usr/include/mysql
'/usr/include/mysql' -> '/usr/local/mysql/include/'
[root@mr mysql]# vim /etc/ld.so.conf.d/mysql.conf

/usr/local/mysql/lib/
[root@mr mysql]# ldconfig
[root@mr mysql]# vim /etc/man_db.conf
MANDATORY_MANPATH                       /usr/man
MANDATORY_MANPATH                       /usr/share/man
MANDATORY_MANPATH                       /usr/local/share/man
MANDATORY_MANPATH                       /usr/local/mysql/man

*
1. 建立数据存放目录,初始化数据库

[root@mr ~]# mkdir /opt/data
[root@mr ~]# ll /opt/data/
total 0
[root@mr ~]# chown -R mysql.mysql /opt/data/
[root@mr ~]# mysqld --initialize --user mysql --datadir /opt/data/

[root@mr ~]#
[root@mr ~]# echo '-ff3uq#Fee%k' > pass
[root@mr ~]# cat pass

*
1. 生成配置文件

[root@mr ~]# vim /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/data/mysql.pid
user = mysql
skip-name-resolve
sql-mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

*
1. 配置服务启动脚本,启动mysql


[root@mr mysql]# cd support-files/
[root@mr support-files]# ls
magic  mysqld_multi.server  mysql-log-rotate  mysql.server
[root@mr support-files]# file mysql.server
mysql.server: POSIX shell script, ASCII text executable
[root@mr support-files]#
方法一:
[root@mr ~]# /usr/local/mysql/support-files/mysql.server start
Starting MySQL.Logging to '/opt/data/mr.err'.

 SUCCESS!
