RHEL 7.2 安装 MySQL 5.7.11 二进制版

共计 4604 个字符，预计需要花费 12 分钟才能阅读完成。

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).

2016-12-04T13:33:02.120080Z 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:

mysql> set password=’1qaz!QAZ’;

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;

到此，MySQL5.7.11 安装完成。
