执行用户 root , 安装使用用户 centralight
1.更新yum
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm
2.安装
yum install Percona-Server-client-56 Percona-Server-server-56
安装如果有冲突，之前已经安装过mysql，则需要卸载
rpm -qa | grep mysql
rpm -qa | grep mariadb
rpm -e [软件标识]
3.非多实例配置及启动
默认配置文件路径 /etc/my.cnf
初始化
mysql_install_db --user=centralight --datadir=/cl/data/mysql/percona3311
启动
mysqld_safe --user=centralight --datadir=/cl/data/mysql --defaults-file=/cl/dist/conf/mysql/my.cnf
4.多实例配置及启动
chown -R centralight /cl/data/mysql/percona3311
mysql_install_db --datadir=/cl/data/mysql/percona3311 --user=centralight
所有配置文件目录
默认配置文件路径 /etc/my.cnf,修改成如下
[client]
user = root
password = 123
# Here follows entries for some specific programs
[mysqld_multi]
mysqld = /usr/bin/mysqld_safe
mysqladmin = /usr/bin/mysqladmin
[mysqld3311]
socket = /var/lib/mysql/mysql3311.sock
port = 3311
datadir = /cl/data/mysql/percona3311
pid-file = /var/lib/mysql/hostname.pid3311
user = centralight
skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
启动
mysqld_multi --defaults-file=/etc/my.cnf --log=/cl/log/mysql/mysql.log start 3311
报告状态
mysqld_multi --defaults-file=/etc/my.cnf report 3311
5.登陆数据库修改用户及权限，并能远程连接
mysql -uroot -p -h127.0.0.1 -P3311
mysql> use mysql;
mysql> update user set host='%’ where host = ‘localhost’ and user=‘root’
mysql> flush privileges;
设置密码
mysql> UPDATE user SET Password=password("123") WHERE user='root' and host='%’;
mysql> flush privileges;
如果不能远程连接，请关闭防火墙尝试
CentOS 7.0默认使用的是firewall作为防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
