Linux-CentOS6.9安装MySQL-5.7.22

Linux-CentOS6.9安装MySQL-5.7.22

创建mysql用户组和用户

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql   # 使用-r参数表示mysql用户是一个系统用户 不能登录 /usr/sbin/useradd -r -g mysql mysql

安装mysql依赖

yum install libaio

下载mysql

cd /data0/software
wget -c https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

或手动下载

进入
https://dev.mysql.com/downloads/mysql/

进入
https://dev.mysql.com/downloads/mysql/5.7.html#downloads

选择 Linux - Generic

Linux - Generic (glibc 2.12) (x86, 64-bit), Compressed TAR Archive

下载
mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

解压到安装目录 /usr/local

tar -zxvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local

重命名

cd /usr/local
mv mysql-5.7.22-linux-glibc2.12-x86_64 mysql-5.7.22

mysql权限

chmod +w /usr/local/mysql-5.7.22
chown -R mysql:mysql /usr/local/mysql-5.7.22

到此mysql安装完毕；接下来我们创建一个mysql实例

创建mysql数据库存放目录

mkdir -p /data0/mysql/3306/data/
mkdir -p /data0/mysql/3306/binlog/
mkdir -p /data0/mysql/3306/relaylog/
chown -R mysql:mysql /data0/mysql/

初始化数据库

在5.7.6版本以前使用 mysql_install_db

/usr/local/mysql-5.7.22/bin/mysql_install_db --basedir=/usr/local/mysql-5.7.22 --datadir=/data0/mysql/3306/data --user=mysql

mysql-5.7.22 使用 mysqld –initialize

/usr/local/mysql-5.7.22/bin/mysqld --user=mysql --basedir=/usr/local/mysql-5.7.22 --datadir=/data0/mysql/3306/data --initialize

显示信息如下；记录下最后一行 root@localhost: Oeh5jU%nrYpy mysql生成的root临时密码；Oeh5jU%nrYpy

mysql配置

vi /etc/my3306.cnf

[mysqld]
basedir=/usr/local/mysql-5.7.22/
datadir=/data0/mysql/3306/data/
socket=/tmp/mysql3306.sock
user=mysql
port=3306

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysqld_safe]
log-error=/tmp/mysqld3306.log
pid-file=/tmp/mysqld3306.pid

[client]
socket = /tmp/mysql3306.sock

启动mysql服务

/usr/local/mysql-5.7.22/bin/mysqld_safe --defaults-file=/etc/my3306.cnf &

查看是否启动成功

ps -ef |grep mysql

能看到类似下面的信息，说明启动成功；

/bin/sh /usr/local/mysql-5.7.22/bin/mysqld_safe --defaults-file=/etc/my3306.cnf
/usr/local/mysql-5.7.22/bin/mysqld --defaults-file=/etc/my3306.cnf --basedir=/usr/local/mysql-5.7.22/ --datadir=/data0/mysql/3306/data --plugin-dir=/usr/local/mysql-5.7.22//lib/plugin --user=mysql --log-error=/tmp/mysqld3306.log --pid-file=/tmp/mysqld3306.pid --socket=/tmp/mysql3306.sock

连接mysql

/usr/local/mysql-5.7.22/bin/mysql -uroot -pOeh5jU%nrYpy -P3306 -hlocalhost

如果连接不上加 -S参数

/usr/local/mysql-5.7.22/bin/mysql -uroot -pOeh5jU%nrYpy -S /tmp/mysql3306.sock

连上后，在做任何操作前，mysql要求要改掉root的临时密码后才能进行操作；

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> alter user 'root'@'localhost' identified by 'xxxxxxx';

alter user 'root'@'localhost' identified by '123456';

接下来我们再创建一个mysql实例，与第一个实例步骤一样，换一下端口就可以了；

创建mysql数据库存放目录

mkdir -p /data0/mysql/3307/data/
mkdir -p /data0/mysql/3307/binlog/
mkdir -p /data0/mysql/3307/relaylog/
chown -R mysql:mysql /data0/mysql/

初始化mysql3307数据库，记录临时密码

/usr/local/mysql-5.7.22/bin/mysqld --user=mysql --basedir=/usr/local/mysql-5.7.22 --datadir=/data0/mysql/3307/data --initialize

2018-04-25T04:25:30.859338Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use –explicit_defaults_for_timestamp server option (see documentation for more details).

2018-04-25T04:25:33.195451Z 1 [Note] A temporary password is generated for root@localhost: phHPJKKOr0/_

mysql3307配置 与3306配置一样，把全部3306改为3307

vi /etc/my3307.cnf

启动mysql3307

/usr/local/mysql-5.7.22/bin/mysqld_safe --defaults-file=/etc/my3307.cnf &

连接mysql3307 并更改临时密码

/usr/local/mysql-5.7.22/bin/mysql -uroot -p'phHPJKKOr0/_' -P3307 -hlocalhost

mysql> alter user 'root'@'localhost' identified by '123456';

创建快捷方式

ln -s /usr/local/mysql-5.7.22/bin/mysql /usr/bin/mysql

连接mysql不用输入全路径了

mysql -uroot -p123456

mysql -uroot -p123456 -P3307
