下載路徑：

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

2.1#創建mysql的數據目錄，該目錄在初始化數據庫的候會用到

mkdir -p /data/mysql/data

mkdir -p /data/mysql/log

 

2.2#移動mysql文件到/data/mysql/mysql

tar -zxvf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz -C /usr/local/

cd /usr/local/

ln -s mysql-5.7.26-linux-glibc2.12-x86_64 mysql

2.3 #先創建mysql組

groupadd mysql

2.4#將MySQL用戶加入mysql組

useradd -r -g mysql -s /bin/false mysql     

2.5#修改目錄權限

chown -R mysql:mysql /data/mysql/

chmod 750 /data/mysql

2.6#配置my.cnf

ls -l /etc/my.cnf ##查看是不是已經有my.cnf配置了，如果有可能是centos自帶了Mysql數據庫，我用的是7.5，自帶mysql 的mariadb，下面我將把它卸載，避免受到干擾

rpm -e mariadb-libs --nodeps ##mariadb

       vim /etc/my.cnf

2.7#初始化數據庫

 

/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/data/mysql/mysql --datadir=/data/mysql/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp #初始化mysql

2.7#根據配置了my.cnf的error.log，查看初始密碼

grep 'password' /data/mysql/log/mysql-error.log  

  2.8#創建ssl加密

/usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/data/mysql/data

2.9#將里面的basedir和datadir改為和my.cnf一致

vi /usr/local/mysql/support-files/mysql.server            

basedir=/usr/local/mysql

datadir=/data/mysql/data

2.10#拷貝和配置啟動文件

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld     

2.11設置開機啟動

chkconfig --add mysqld

chkconfig mysqld on

 

2.12配置環境變量

echo 'PATH=/usr/local/mysql/bin:$PATH'>>/etc/profile

tail -1 /etc/profile

source /etc/profile   #讓環境變量生效

echo $PATH #檢查變量是否添加成功

2.13#啟動mysql

service mysqld start 

2.14#進入mysql

mysql -uroot -p         #密碼通過前面的2.2.7找到

2.15#修改初始密碼

ALTER USER ' root'@'localhost ' IDENTIFIED BY ' 123456 ';    

2.16#刷新權限

flush privileges; 

2.17加入開機啟動項
