二进制安装mysql

1. 首先。要有软件包mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

1. [root@bogon ~]#yum -y install libaio
2. [root@bogon ~]#tar zxf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz -C /usr/local
3. [root@bogon ~]# cd /usr/local/
4. [root@bogon local]# mv mysql-5.7.24-linux-glibc2.12-x86_64/ mysql
5. [root@bogon local]# useradd -M -s /sbin/nologin mysql
6. [root@bogon local]# cd mysql/
7. [root@bogon mysql]# chown -R mysql:mysql ./
8. [root@bogon mysql]# ./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize
9. [Note] A temporary password is generated for root@localhost: ho19hx,%sZNq

记住上面这一行的密码。这个是初始密码。每一台机器的初始密码都不一样。

　　10. 修改/etc/my.cnf文件。(因为我们的mysql安装在/usr/local/下的，所以需要重新定义)

[mysqld]

datadir=/usr/local/mysql/data

socket=/tmp/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

# Settings user and group are ignored when systemd is used.

# If you need to run mysqld under a different user or group,

# customize your systemd unit file for mariadb according to the

# instructions in http://fedoraproject.org/wiki/Systemd

 

[mysqld_safe]

log-error=/usr/local/mysql/data/mysql.log

pid-file=/usr/local/mysql/data/mysql.pid

到这一步其实就已经做完了，后面的都是起服务跟优化

　　11. [root@bogon mysql]# ./support-files/mysql.server start

　　12 . [root@bogon mysql]# netstat -anpt |grep 3306

　　13. [root@bogon mysql]# cp support-files/mysql.server /etc/init.d/mysqld

　　14. [root@bogon mysql]# service mysqld restart

　　15. [root@bogon mysql]# ./bin/mysqladmin -u root -p password '123123'

　　16. [root@bogon mysql]# ln -s /usr/local/mysql/bin/* /usr/local/bin

　　17. [root@bogon mysql]#service mysql restart
