# preparegroupadd mysqluseradd -r -g mysql -s /bin/false mysqlyum install -y autoconfmkdir /appsmkdir /logsmkdir /datamkdir -p /data/mysql7006/data && chown -R mysql:mysql /data/mysql7006mkdir /logs/mysql7006 && chown -R mysql:mysql /logs/mysql7006touch /logs/mysql7006/error-log.err && chown -R mysql:mysql /logs/mysql7006/error-log.err

4.安装

cd /tmptar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gzmv mysql-5.7.18-linux-glibc2.5-x86_64 mysqlmv mysql /apps/mysqlcp my.cnf /apps/mysql/chown -R mysql:mysql /apps/mysql/# 初始化数据库，cd /apps/mysql./bin/mysqld --initialize --user=mysql --basedir=/apps/mysql/ --datadir=/data/mysql7006/data/

初始化过程中会生成一个默认密码记得记下来，后续修改用。

5.注册service（可以不做）

# 依据情况修改support-files/mysql.servercp support-files/mysql.server /etc/init.d/mysqlsystemctl start mysql.service# 添加开机启动chkconfig mysql.server on

6.启动数据库/apps/mysql/bin/mysqld_safe --defaults-file=/apps/mysql/my.cnf &

7.修改默认密码：

/apps/mysql/bin/mysqladmin -u root password 'password' --port=7006 --socket=/data/mysql7006/mysql.sock -p# 修改后清空linux的history记录history -c# 登陆测试：/apps/mysql/bin/mysql -u root --port=7006 --socket=/data/mysql7006/mysql.sock -p

8.防火墙、赋权（按需做）

# 防火墙firewall-cmd --zone=public --add-port=7006/tcp --permanentsystemctl restart firewalldfirewall-cmd --zone=public --query-port=7006/tcp# 赋权给登陆用户use mysql;grant all privileges on *.* to user@'ip' identified by "password";flush privileges;select host,user,password from user;

9.本地隐藏密码登录（可以不做）

## 使用mysql_config_editor 制作登录文件/apps/mysql/bin/mysql_config_editor set --login-path=root_pass --user=root --port=7006 --socket=/data/mysql7006/mysql.sock --password## 输入密码：******## 文件会加密存储于用户根目录下.mylogin.cnf/apps/mysql/bin/mysql_config_editor print --all## 下次登录时直接敲：/apps/mysql/bin/mysql --login-path=root_pass# 再省事一些：set alias# 打开file .bashrc，添加alias db7006='/apps/mysql/bin/mysql --login-path=root_pass'# 然后退出执行：source .bashrc## 下次登录时直接敲：db7006

my.cnf文件

主要功能：全局utf8字符集、自定义端口、数据文件夹、日志文件夹、默认引擎innodb（支持事务，对xtrabackup友好）、跳过客户端登陆时的dns解析
