0.创建mysql用户和组信息[root@gxoradb1 ~]# groupadd mysql [root@gxoradb1 ~]# useradd -r -g mysql -s /bin/false mysql
1.指定安装目录[root@gxoradb1 ~]# cd /usr/local [root@gxoradb1 local]# ls mysql-advanced-5.7.15-linux-glibc2.5-x86_64.tar.gz
2.解压mysql[root@gxoradb1 local]# tar -zxvf mysql-advanced-5.7.15-linux-glibc2.5-x86_64.tar.gz [root@gxoradb1 local]# mv mysql-advanced-5.7.15-linux-glibc2.5-x86_64/ mysql-5.7.15 [root@gxoradb1 local]# ln -s mysql-5.7.15 mysql [root@gxoradb1 local]# ls -la lrwxrwxrwx  1 root root   12 Oct  4 14:58 mysql -> mysql-5.7.15 drwxr-xr-x  9 root root  4096 Oct  4 14:56 mysql-5.7.15
3.调整目录权限[root@gxoradb1 local]# cd mysql [root@gxoradb1 mysql]# mkdir mysql-files[root@gxoradb1 mysql]# chmod 750 mysql-files [root@gxoradb1 mysql]# chown -R mysql:mysql .
The mysql-files directory provides a convenient location to use as the value of the secure_file_priv system variable that limits import/export operations to a specific directory.
4.初始化mysql[root@gxoradb1 mysql]# bin/mysqld --initialize --user=mysql2016-10-04T07:07:05.044029Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2016-10-04T07:07:05.351321Z 0 [Warning] InnoDB: New log files created, LSN=45790 2016-10-04T07:07:05.396915Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2016-10-04T07:07:05.454329Z 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: 2825c52a-8a01-11e6-abb2-080027b5eb23. 2016-10-04T07:07:05.456104Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened. 2016-10-04T07:07:06.265334Z 0 [Warning] CA certificate ca.pem is self signed. 2016-10-04T07:07:06.503976Z 1 [Note] A temporary password is generated for root@localhost: <5Tk+Gs7frb7 //临时口令[root@gxoradb1 mysql]# bin/mysql_ssl_rsa_setup
5.调整目录权限[root@gxoradb1 mysql]# chown -R root . [root@gxoradb1 mysql]# chown -R mysql data mysql-files
6.启动mysql[root@gxoradb1 mysql]# bin/mysqld_safe --user=mysql & [1] 11211 [root@gxoradb1 mysql]# 2016-10-04T07:10:20.032700Z mysqld_safe Logging to '/usr/local/mysql/data/gxoradb1.err'. 2016-10-04T07:10:20.058270Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
7.创建自启动脚本[root@gxoradb1 mysql]# cp support-files/mysql.server /etc/init.d/mysql.server [root@gxoradb1 mysql]# chkconfig --add mysql.server [root@gxoradb1 mysql]# chkconfig --list mysql.server   mysql.server   0:off  1:off  2:on   3:on   4:on   5:on   6:off
8.登录mysql数据库[root@gxoradb1 ~]# mysql -u root -h localhost -p Enter password: Welcome to the MySQL monitor.  Commands end with ; or \g. Your MySQL connection id is 5 Server version: 5.7.15-enterprise-commercial-advanced Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved.
