首先需要下載安裝文件3個：
MySQL-client-5.6.37-1.el7.x86_64.rpm?
MySQL-devel-5.6.37-1.el7.x86_64.rpm?
MySQL-server-5.6.37-1.el7.x86_64.rpm
使用rpm安裝
rpm -ivh ./MySQL-server-5.6.37-1.el7.x86_64.rpm
若需查詢移除：
rpm -qa | grep -i MySQL
rpm -e MySQL-server-5.6.37-1.el7.x86_64.rpm
然后配置my.cnf到/etc下
my.cnf內容如下：
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
innodb_buffer_pool_size = 64M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
user=mysql
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
join_buffer_size = 64M
sort_buffer_size = 2M
read_rnd_buffer_size = 2M
key_buffer_size = 64M
performance_schema_max_table_instances=400
table_definition_cache=400
table_open_cache=256
[client]
socket=/var/lib/mysql/mysql.sock
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
使用如下命令啟動
/etc/init.d/mysql start
第一次啟動會創(chuàng)建一個隨機密碼，位于
/root/.mysql_secret最后一行
修改登陸密碼百新，登陸
mysql -u root -p
輸入剛才的隨機密碼，進入mysql命令行
第一次登陸不能輸入其它命令址貌，需執(zhí)行修改密碼命令
SET PASSWORD=PASSWORD('123456');
然后修改遠程登陸的用戶名和密碼
use mysql;
update user set password=PASSWORD("123456") where user='root';
FLUSH PRIVILEGES;
quit;
若遠程登陸失敗，可mysql執(zhí)行如下胸嘁，插入遠程登陸用戶名
use mysql;
update user set host='%' where user='root';
FLUSH PRIVILEGES;
安裝完成虑椎，
