标签:mysql5.7 安装
操作系统:rhel7.2
MySQL版本:5.7.11
1、MySQL下载
http://dev.mysql.com/downloads/
2、上传MySQL软件到操作系统
[root@rhel7 ~]# ls -l mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -rw-r--r--. 1 root root 548193637 Dec 4 21:16 mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
3、添加mysql用户和组
[root@rhel7 ~]# groupadd mysql [root@rhel7 ~]# useradd -r -g mysql -s /bin/false mysql [root@rhel7 ~]# id mysql uid=996(mysql) gid=1000(mysql) groups=1000(mysql)
4、创建目录、改属组及解压文件
[root@rhel7 ~]# mkdir -p /opt/mysql/ [root@rhel7 ~]# mkdir /mysqldata [root@rhel7 ~]# mv /root/mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz /opt/mysql/ [root@rhel7 ~]# cd /opt/mysql/ [root@rhel7 mysql]# ls mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz [root@rhel7 mysql]# tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz ...... [root@rhel7 mysql]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql5.7.11 [root@rhel7 mysql]# ls -l total 535352 drwxr-xr-x. 9 7161 wheel 4096 Feb 2 2016 mysql5.7.11 -rw-r--r--. 1 root root 548193637 Dec 4 21:16 mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz [root@rhel7 mysql]# chown mysql:mysql -R /opt/mysql/ [root@rhel7 mysql]# chown mysql:mysql -R /mysqldata/
5、初始化库
[root@rhel7 mysql]# cd mysql5.7.11/ [root@rhel7 mysql5.7.11]# ./bin/mysqld --initialize --user=mysql --basedir=/opt/mysql/mysql5.7.11/ --datadir=/mysqldata/ 2016-12-04T13:33:01.318081Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2016-12-04T13:33:01.729086Z 0 [Warning] InnoDB: New log files created, LSN=45790 2016-12-04T13:33:02.027182Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2016-12-04T13:33:02.111882Z 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: 2dca0cf3-ba26-11e6-b4ff-080027e818bc. 2016-12-04T13:33:02.118970Z 0 [Warning] Gtid table is not ready to be used. Table ‘mysql.gtid_executed‘ cannot be opened. 2016-12-04T13:33:02.120080Z 1 [Note] A temporary password is generated for root@localhost: rqwPw!9iNEEP [root@rhel7 mysql5.7.11]# ls /mysqldata/ auto.cnf ib_buffer_pool ibdata1 ib_logfile0 ib_logfile1 mysql performance_schema sys
注意:root的初始密码已经在日志中给出:rqwPw!9iNEEP
在5.7.6之前的版本中使用bin/mysql_install_db --user=mysql初始化库。
6、启动MySQL数据库
#替换系统自带的my.cnf文件 [root@rhel7 mysql5.7.11]# mv /etc/my.cnf /etc/my.cnf.bak [root@rhel7 mysql5.7.11]# cp support-files/my-default.cnf /etc/my.cnf #在my.cnf中添加如下两条 [root@rhel7 mysql5.7.11]# vi /etc/my.cnf basedir = /opt/mysql/mysql5.7.11 datadir = /mysqldata #启动MySQL [root@rhel7 mysql5.7.11]# ./bin/mysqld_safe --user=mysql & [1] 1756 [root@rhel7 mysql5.7.11]# 2016-12-04T13:44:30.046089Z mysqld_safe Logging to ‘/mysqldata/rhel7.err‘. 2016-12-04T13:44:30.097978Z mysqld_safe Starting mysqld daemon with databases from /mysqldata [root@rhel7 mysql5.7.11]# ps -ef |grep mysql root 1756 1182 0 21:44 pts/0 00:00:00 /bin/sh ./bin/mysqld_safe --user=mysql mysql 1876 1756 1 21:44 pts/0 00:00:00 /opt/mysql/mysql5.7.11/bin/mysqld --basedir=/opt/mysql/mysql5.7.11 --datadir=/mysqldata --plugin-dir=/opt/mysql/mysql5.7.11/lib/plugin --user=mysql --log-error=/m ysqldata/rhel7.err --pid-file=/mysqldata/rhel7.pidroot 1905 1182 0 21:44 pts/0 00:00:00 grep --color=auto mysql
7、登录MySQL,使用安装时给出密码登录并更改root密码
[root@rhel7 mysql5.7.11]# ./bin/mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.11 Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. mysql> set password=‘1qaz!QAZ‘; Query OK, 0 rows affected (0.01 sec)
注意:5.6之前使用set password=password(‘newpassword‘)进行改密码,5.7版本不再建议这样改密码,会有如下提示:
mysql> set password=password(‘123456‘); Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> show warnings; +---------+------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Level | Code | Message | +---------+------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Warning | 1287 | ‘SET PASSWORD = PASSWORD(‘<plaintext_password>‘)‘ is deprecated and will be removed in a future release. Please use SET PASSWORD = ‘<plaintext_password>‘ instead | +---------+------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec)
到此,MySQL5.7.11安装完成。
