二进制安装mysql5.7_CentOS-7 二进制安装mysql5.7.31

1、环境准备

虚拟机：centos 7 ip：192.168.137.128

mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz   https://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz

2、开始安装

添加mysql用户

useradd mysql -s /sbin/nologin

解压mysql二进制包并重命名

tar -zxf mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz

mv mysql-5.7.31-linux-glibc2.12-x86_64 mysql

新建mysql 数据存储目录data，以及创建my.cnf配置文件

my.cnf配置文件参考

[mysql]

port=3306

socket=/usr/local/mysql/mysql.sock

default-character-set=utf8

[mysqld_safe]

log-error=/usr/local/mysql/data/mysql.error

[mysqld]

port=3306

user=mysql

basedir=/usr/local/mysql

datadir=/usr/local/mysql/data

socket=/usr/local/mysql/mysql.sock

pid-file=/usr/local/mysql/mysql.pid

character-set-server=utf8

skip-name-resolve

lower_case_table_names=1

query_cache_size=0

transaction_isolation=READ-COMMITTED

tmp_table_size=128M

max_heap_table_size=96M

max_connections=1000

max_connect_errors=6000

long_query_time=1

innodb_buffer_pool_size=2G

innodb_flush_log_at_trx_commit=0

innodb_log_buffer_size=8M

innodb_log_file_size=128M

innodb_log_files_in_group=2

innodb_file_per_table=1

innodb_flush_method=O_DIRECT

innodb_file_format=Barracuda

innodb_write_io_threads=8

innodb_read_io_threads=4

innodb_doublewrite=0

innodb_purge_threads=1

innodb_stats_on_metadata=OFF

innodb_io_capacity=1000

log-bin-trust-function-creators=1

event_scheduler=on

初始化数据库

修改mysql目录的属主和属组

chown mysql:mysql mysql -R

初始化数据库

/usr/local/mysql/bin/mysqld --defaults-file=/usr/local/mysql/my.cnf --initialize  --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

记录mysql初始化临时密码

修改mysql目录下support-files目录中的mysql.server文件

修改basedir和datadir

启动mysql服务

./mysql.server start

使用mysql临时随机密码登录数据库修改root密码，密码为强制修改，否则无法正常使用

./mysql -S/usr/local/mysql/mysql.sock -uroot -p

修改密码

ALTER USER USER() IDENTIFIED BY '密码';

flush privileges;       # 刷新mysql表授权

到此，mysql二进制安装完成！
