CentOs7.x 安装 MySQL 5.7.36二进制版本
下载地址
1.准备工作
依赖环境
关闭防火墙
systemctl stop firewalld.service
MySQL依赖于libaio 库
yum search libaio
yum install libaio
下载，解压，重命名
通常解压在 /usr/local/mysql
cd /opt
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.36-linux-glibc2.12-x86_64.tar.gz
tar -zxvf /opt/mysql-5.7.36-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
mv /usr/local/mysql-5.7.36-linux-glibc2.12-x86_64/ /usr/local/mysql
解压目录内容
bin mysqld服务器，客户端和实用程序
data 日志文件，数据库
docs MySQL手册信息格式
man Unix手册页
include 包含（标题）文件
lib 库
share 其他支持文件，包括错误消息，示例配置文件，用于数据库安装的SQL
2.安装MySQL
1. 新建用户组和用户
cd /usr/local/mysql/
groupadd mysql
useradd mysql -g mysql
2. 创建目录并授权
mkdir data mysql-files
chmod 750 mysql-files
chown -R mysql .
chgrp -R mysql .
3. 初始化MySQL
bin/mysqld --initialize --user=mysql
4. mysql 临时密码
2017-08-26T03:23:35.368366Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2017-08-26T03:23:35.748679Z 0 [Warning] InnoDB: New log files created, LSN=45790
2017-08-26T03:23:35.793190Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2017-08-26T03:23:35.848286Z 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: f210c54b-8a0d-11e7-abbd-000c29129bb0.
2017-08-26T03:23:35.848889Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2017-08-26T03:23:35.849421Z 1 [Note] A temporary password is generated for root@localhost: ;b;s;)/rn6A3
5. 生成RSA私钥，可以跳过此步骤
mysql_ssl_rsa_setup需要openssl支持，用于启用数据量ssl连接，需要进一步配置。
参考-MySQL 使用 SSL 连接
bin/mysql_ssl_rsa_setup
6. 授予读写权限
chown -R root .
chown -R mysql data mysql-files
7. 添加到MySQL 启动脚本到系统服务
cp support-files/mysql.server /etc/init.d/mysql.server
3.启动MySQL服务
启动脚本有两个分别是：
当启动mysqld时，mysqld_safe同时启动
mysqld_safe监控mysqld服务,记录错误日志，并在mysqld因故障停止时将其重启
启动方式一
bin/mysqld_safe --user=mysql &
或者
/usr/local/mysql/support-files/mysql.server start
如若出现报错
Starting MySQL.2017-08-26T07:31:24.312411Z mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
ERROR! The server quit without updating PID file (/var/lib/mysql/node1.pid).
给日志目录授予读写权限
mkdir /var/log/mariadb
touch /var/log/mariadb/mariadb.log
chown -R mysql:mysql /var/log/mariadb
4.登录MySQL
/usr/local/mysql/bin/mysql -uroot -p
Enter password:
设置MySQL密码
登陆成功后，设置MySQL密码
mysql> ALTER USER 'root'@'localhost' identified by 'mima';
或者
mysql> set password=password("mima");
刷新权限
mysql> flush privileges;
mysql> exit;
开启远程登录
关闭防火墙
systemctl stop firewalld.service
以权限用户root登录
$ /usr/local/mysql/bin/mysql -uroot -p
mysql> use mysql;
mysql> update user set host = '%' where user ='root';
mysql> flush privileges;
第1行：选择mysql库
第2行：修改host值（以通配符%的内容增加主机/IP地址），当然也可以直接增加IP地址
第3行：刷新MySQL的系统权限相关表
或者
mysql> grant all privileges on *.* to 'root'@'%' identified by 'mima' with grant option;
mysql> flush privileges;
