安装mysql-5.7.25-linux-glibc2.12
在减压包的时候注意将包压缩到 、/usr/local/ 下面
在官网：http://dev.mysql.com/downloads/mysql/ 中，选择以下版本的mysql下载：
1、解压压缩包到目标位置
--解压压缩包
[[email protected] tools]# tar -zxvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz
--移动并修改文件名
[[email protected] tools]# mv mysql-5.7.25-linux-glibc2.12-x86_64 /usr/local/mysql [[email protected] mysql]# pwd
| /home/usr/mysql |
2、创建数据仓库目录
[[email protected] mysql]# mkdir data/mysql
新建mysql用户、组及目录
[[email protected] mysql]# groupadd mysql [[email protected] mysql]# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql
3、改变目录属有者
[[email protected] mysql]# chown -R mysql . [[email protected] mysql]# chgrp -R mysql . [[email protected] mysql]# chown -R mysql /data/mysql [[email protected] data]# cd .. [[email protected] mysql]# chown -R mysql data/mysql [[email protected] mysql]# ls bin COPYING data docs include lib man README share support-files
4、配置参数
[[email protected] mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mysql
| 2019-01-28T07:37:54.141689Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2019-01-28T07:37:54.468955Z 0 [Warning] InnoDB: New log files created, LSN=45790 2019-01-28T07:37:54.533436Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2019-01-28T07:37:54.599965Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 9fcb80c7-22cf-11e9-92c7-fa163ef336d3. 2019-01-28T07:37:54.602975Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened. 2019-01-28T07:37:54.603403Z 1 [Note] A temporary password is generated for [email protected]: q0_wqowE8gk5 |
此处需要注意记录生成的临时密码，如上文结尾处的：q0_wqowE8gk5
5、使用脚本工具生成**文件
[[email protected] mysql]# bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data/mysql
Generating a 2048 bit RSA private key ......................................................................+++ ..................+++ writing new private key to 'ca-key.pem' ----- Generating a 2048 bit RSA private key ..................................................................................+++ ....................................................+++ writing new private key to 'server-key.pem' ----- Generating a 2048 bit RSA private key ...............................................+++ ....................................+++ writing new private key to 'client-key.pem' -----
6、修改系统配置文件
[[email protected] mysql]# cd support-files/ [[email protected] support-files]# ls magic mysqld_multi.server mysql-log-rotate mysql.server [[email protected] support-files]# cp mysql.server /etc/init.d/mysql
7、修改以下内容
[[email protected] mysql]# vi /etc/my.cnf
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
port=3307
datadir=/usr/local/mysql/data/mysql
skip-grant-tables
[[email protected] mysql]# /etc/init.d/mysql start
Starting MySQL.Logging to '/home/yoodb/mysql/data/mysql/ecs-1b35-0002.novalocal.err'.
SUCCESS!
8、启动mysql
[[email protected] mysql]# ln -s /usr/local/mysql/bin/mysql /usr/bin [[email protected] my.cnf.d]# service mysql start [[email protected] mysql]# mysql -hlocalhost -uroot -p Enter password: 输入生成的临时密码 Welcome to the MySQL monitor.

Type '\c' to clear the current input statement. --修改密码 mysql> set password=password('[email protected]#'); Query OK, 0 rows affected, 1 warning (0.00 sec) --设置root账户的host地址（修改可以远程连接） mysql> grant all privileges on *.* to 'root'@'%' identified by 'root'; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> exit; Bye
这样就可以使用远程连接数据了。
9、添加系统路径
# vim /etc/profile
添加：
export PATH=/home/yoodb/mysql/bin:$PATH [[email protected] mysql]# source /etc/profile
10、配置mysql自动启动
[[email protected] mysql]# chmod 755 /etc/init.d/mysql [[email protected] mysql]# chkconfig --add mysql [[email protected] mysql]# chkconfig --level 345 mysql on
