OEL7.6源码安装MYSQL5.7的好代码教程

首先官网下载安装包https://dev.mysql.com/downloads/mysql/5.7.html#downloads

然后上传解压至/usr/local目录

[root@localhost db]# tar -xf mysql-5.7.26-linux-glibc2.12-x86_64.tar 
[root@localhost db]# tar -xzf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz 
[root@localhost db]# mv mysql-5.7.26-linux-glibc2.12-x86_64 /usr/local/mysql
[root@localhost db]# 

然后创建mysql用户和组以及数据目录

[root@localhost db]# mv mysql-5.7.26-linux-glibc2.12-x86_64 /usr/local/mysql
[root@localhost db]# groupadd mysql
[root@localhost db]# useradd mysql -g mysql
[root@localhost db]# cd /usr/local/mysql
[root@localhost mysql]# mkdir data
[root@localhost mysql]# chown mysql: -R /usr/local/mysql/
[root@localhost mysql]# 

然后初始化数据并记录临时密码

[root@localhost mysql]# bin/mysqld --initialize --user=mysql --datadir /usr/local/mysql/data
2019-07-26T01:34:24.479757Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2019-07-26T01:34:24.724629Z 1 [Note] A temporary password is generated for root@localhost: ucZ5w5ZkSq;1
[root@localhost mysql]#

然后修改/etc/my.cnf配置文件中datadir为/usr/local/mysql/data

[root@localhost mysql]# cat /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
[root@localhost mysql]# 

然后将mysql加入init.d目录并启动mysql

[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/usr/local/mysql/data/localhost.localdomain.err'.
 SUCCESS! 
[root@localhost mysql]# ps -ef|grep mysql
root   12957   1 0 09:37 pts/0  00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/localhost.localdomain.pid
mysql  13057 12957 4 09:37 pts/0  00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=localhost.localdomain.err --pid-file=/usr/local/mysql/data/localhost.localdomain.pid
root   13092 10198 0 09:37 pts/0  00:00:00 grep --color=auto mysql
[root@localhost mysql]# 

最后mysql/bin加入path,并登陆数据库并重设密码

[root@localhost bin]# ./mysql -u root -p
Enter password:
