mysql-5.7.26 安装

一、准备环境

Mysql 安装包

下载地址

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

 

二、解压安装包

2.1我这里使用的目录/home/ap

tar -zvxf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz -C

2.2修改名称

mv mysql-5.7.26-linux-glibc2.12-x86_64 mysql

2.3创建data 和 log目录（我这里没有创建，初始化失败，可以不创建初始化尝试一下）

三、创建Mysql用户

useradd mysql

3.1 赋予mysql 目录 Mysql权限

chown mysql.mysql -R /home/ap/mysql

3.2初始化

/home/ap/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/home/ap/mysql --datadir=/home/ap/mysql/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp

3.2查询登录密码

grep 'password' /home/ap/mysql/log/mysql-error.log

3.3修改启动服务指定data 和 base目录(可以忽略这步)

vi /home/ap/mysql/support-files/mysql.server

basedir=/home/ap/mysql
datadir=/home/ap/mysql/data

3.4拷贝启动配置文件

cp /home/ap/mysql/support-files/mysql.server /etc/init.d/mysql

3.5赋予执行权限

chmod +x  /etc/init.d/mysql

四、编辑/etc/my.cnf配置文件

4.1

vi /etc/my.cnf

[client]
port = 31061
socket = /home/ap/mysql/mysql.sock
[mysqld]
server_id=10
port = 3306
user = mysql
character-set-server = utf8mb4
default_storage_engine = innodb
log_timestamps = SYSTEM
socket = /home/ap/mysql/mysql.sock
basedir =/home/ap/mysql
datadir = /home/ap/mysql/data
pid-file = /home/ap/mysql/mysql.pid
max_connections = 1000
max_connect_errors = 1000
table_open_cache = 1024
max_allowed_packet = 128M
open_files_limit = 65535
server-id=1
gtid_mode=on
enforce_gtid_consistency=on
log-slave-updates=1
log-bin=master-bin
log-bin-index = master-bin.index
relay-log = relay-log
relay-log-index = relay-log.index
binlog_format=row
log_error = /home/ap/mysql/log/mysql-error.log 
skip-name-resolve
log-slave-updates=1
relay_log_purge = 0 
slow_query_log = 1
long_query_time = 1 
slow_query_log_file = /home/ap/mysql/log/mysql-slow.log 

4.1启动Mysql

/etc/init.d/mysql start

4.2登录mysql  

mysql -uroot -p查询的密码

4.3修改密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Aipf@123'; 

4.4成功
