quick
说明：
请一定记得上面 配置模板文件中的server-id 参数一定要修改。
否则在配置 主从复制，或者MHA时会报错。
例如错误信息 ：
2018-10-09T16:13:53.205115+08:00 11 [ERROR] [MY-013117] [Repl] Slave I/O for channel ‘‘: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the --replicate-same-server-id option must be used on slave but this does not always make sense; please check the manual before using it). Error_code: MY-013117
3. 创建目录并授权
cd /data/mysql
mkdir mysql_log
chown -R mysql.mysql mysql_log/
mkdir tmp
chown -R mysql.mysql tmp/
说明：
有时候，可能我们只是将MYSQL的二进制文件从其它的服务器Copy至本地。
例如我们在安装MYSQL8.0 时，安装文件从其它的服务，Copy到本地，文件命名为mysql80。如下图：
此时还需要执行以下权限，所以 我手动增加了一下权限，执行代码如下：
chmod -R 755 /data/mysql80/bin/
4.初始化MySQL
/data/mysql57/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/data/mysql57 --datadir=/data/mysql/data
说明：
主参数--defaults-file=/etc/my.cnf必须紧接在mysqld后面，如果做第二个以后的参数加入时，则会出现报错：
[ERROR] unknown variable ‘defaults-file=/etc/my.cnf‘！
注意密码：5.7初始化后会生成一个临时密码，存在mysql.err
[Note] A temporary password is generated for root@localhost: XXXXXXXX
也就是root@localhost:后的字符串。
5.添加到MySQL启动脚本到系统服务,并且设置开启启动
cp -a /data/mysql57/support-files/mysql.server /etc/init.d/mysqld
设置开机启动和检查是否成功
chkconfig mysqld on
chkconfig --list | grep mysqld
6. 创建mysql软链接至/usr/bin下
ln -s /data/mysql57/bin/mysql /usr/bin
7.启动MySQL服务
service mysqld start
说明：
如果还是使用的Copy文件的方式，例如我们前面 Copy的mysql80 二进制文件， 此处就会报错：
此时 还要执行以下赋权命令 ：
chmod -R 755 ./mysql.server （这个文件是 /data/mysql80/support-files）
和
chmod -R 755 /etc/init.d/mysqld
8. 登录MySQL，修改root密码
mysql -uroot -pXXXXXXX
mysql> set password=password(‘XXXXXXX2‘);
说明 ：
MySQL 8.0 是报错的：
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘password(‘XXXXX‘)‘ at line 1
在登录MySQL，修改root密码时，使用就方法 SET PASSWORD=PASSWORD(‘[新密码]’) 报错。
查看网上的相关解释为：
以前版本的MySQL的密码认证插件是“mysql_native_password”，而现在使用的是“caching_sha2_password”。
解决方案：
ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘新密码‘;
FLUSH PRIVILEGES;
Linux系统下 MySQL 安装 指南（5.7和8.0 版本）
