Mysql5.7 Linux安装教程
1系统约定
安装文件下载目录：/data/software
Mysql目录安装位置：/mysql
数据库保存位置：/mysql/data
日志保存位置：/mysql/data/log
卸载maridb和原有的mysql服务
> [root@localhost ~]# rpm -qa|grep mysql
qt-mysql-4.8.7-2.el7.x86_64
akonadi-mysql-1.9.2-4.el7.x86_64
[root@localhost ~]# rpm -qa|grep mariadb
mariadb-5.5.56-2.el7.x86_64
mariadb-libs-5.5.56-2.el7.x86_64
mariadb-server-5.5.56-2.el7.x86_64

/sbin/ldconfig: /lib64/libcrypto.so.1.0.0 is not a symbolic link
/sbin/ldconfig: /lib64/libssl.so.1.0.0 is not a symbolic link
[root@localhost ~]# rpm -e --nodeps mariadb-server-5.5.56-2.el7.x86_64
2下载mysql
在官网：http://dev.mysql.com/downloads/mysql/ 中，选择以下版本的mysql下载：
–解压压缩包
#tar -xvf /data/software/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
–移动并修改文件名
#mv /data/software/mysql-5.7.17-linux-glibc2.5-x86_64 /mysql
[root@oceadatabase mysql]# ls
bin docs include lib LICENSE lost+found man mysql-5.7.29-linux-glibc2.12-x86_64 README share support-files
4创建数据仓库目录
#mkdir /mysql/data
#ls /data/
5新建mysql用户、组及目录
—新建一个msyql组
#useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql
—新建msyql用户禁止登录shell
6改变目录属有者
#cd /mysql
#pwd
#chown -R mysql
#chgrp -R mysql .#chown -R mysql /mysql/data
7mysql数据库初始化
#/mysql/bin/mysqld --initialize --user=mysql --basedir=/mysql --datadir=/mysql/data
[root@oceadatabase bin]# /mysql/bin/mysqld --initialize --user=mysql --basedir=/mysql --datadir=/mysql/data
2020-10-13T18:19:08.372727Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2020-10-13T18:19:08.574671Z 0 [Warning] InnoDB: New log files created, LSN=45790
2020-10-13T18:19:08.610122Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2020-10-13T18:19:08.678267Z 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: 95e5f430-0d80-11eb-a233-000c29184797.

2020-10-13T18:19:09.486587Z 1 [Note] A temporary password is generated for root@localhost: q,l;7llwN2Oh
此处需要注意记录生成的临时密码，如上文结尾处的：YLi>7ecpe;YP
#/mysql/bin/mysql_ssl_rsa_setup --datadir=/mysql/data
8修改系统配置文件
#cd /mysql/support-files
#cp my-default.cnf /etc/my.cnf --文件不存在。
#cp mysql.server /etc/init.d/mysql
> # vim /etc/init.d/mysql
修改以下内容：
9 启动mysql
/etc/init.d/mysql start
[root@oceadatabase support-files]# /etc/init.d/mysql start
Starting MySQL… ERROR! The server quit without updating PID file (/var/lib/mysql/oceadatabase.pid).
#strace /etc/init.d/mysql start
/mysql/bin/mysqld_safe --skip-grant-tables &
—通过删除/etc/my.cnf文件，mysql服务启动成功。
–登陆
mysql -hlocalhost -uroot -p
–如果出现：-bash: mysql: command not found
–就执行： # ln -s /usr/local/mysql/bin/mysql /usr/bin
–没有出现就不用执行
–输入第6步生成的临时密码
mysqld_safe --skip-grant-tables &
mysql
–修改密码
use mysql
desc usermysql
desc user
-> ;

update user set authentication_string=password(‘mysql#123’) where user=‘root’;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> alter user root@localhost identified by “ora#123”;
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘your password’;
update user set password=password(“root1234”) where user=‘root’;
CREATE USER ‘clg’@’%’ IDENTIFIED BY ‘your password’;
GRANT ALL ON . TO ‘langguofeng’@’%’;
ALTER USER ‘langguofeng’@’%’ IDENTIFIED BY ‘your password’ PASSWORD EXPIRE NEVER;
ALTER USER ‘langguofeng’@’%’ IDENTIFIED WITH mysql_native_password BY ‘your password’;
mysql> set password=password(‘root’);
–设置root账户的host地址（修改了才可以远程连接）
mysql>grant all privileges on . to ‘root’@’%’ identified by ‘root’;
mysql>flush privileges;
–查看表
mysql> use mysql;
mysql> select host,user from user;
–这里就可以使用远程连接测试了；
10 添加系统路径
vim /etc/profile
添加： export PATH=/usr/local/mysql/bin:$PATH 如下：
source /etc/profile
11 配置mysql自动启动
chmod 755 /etc/init.d/mysql
> # chkconfig --add mysql
> # chkconfig --level 345 mysql on
以上就是linux环境Mysql 5.7.13安装教程，
–查看mysql状态
#service mysql status
[root@oceadatabase ~]# ps -ef|grep mysqld
root 5748 1 0 20:41 pts/1 00:00:00 /bin/sh /mysql/bin/mysqld_safe --datadir=/mysql/data --pid-file=/mysql/data/oceadatabase.pid
mysql 5835 5748 0 20:41 pts/1 00:00:02 /mysql/bin/mysqld --basedir=/mysql --datadir=/mysql/data --plugin-dir=/mysql/lib/plugin --user=mysql --log-error=oceadatabase.err --pid-file=/mysql/data/oceadatabase.pid
–停止mysql
#service mysql stop
–启动mysql
#service mysql start
创建别名连接mysql数据库
[root@oceadatabase ~]# alias mysql=‘mysql -uroot -pmysql#123’
ch
一种添加系统自动启动的办法
chmod 755 /etc/init.d/sh文件
> # chkconfig --add sh文件
> # chkconfig --level 345 mysql on
