一、安装依赖环境：
yum -y install libaio libaio-devel libtool make automake autoconf numactl numactl-devel bzip2 gcc gcc-c++ perl perl-DBI perl-ExtUtils-MakeMaker perl-devel perl-Time-HiRes perl-DBD-MySQL pcre-devel time jemalloc gperf cmake zlib-devel openssl-devel readline-devel readline glib2-devel mysql-devel qpress which netstat
wget http://repositories.voole.com/jemalloc-4.0.4.tar.bz2 tar xjf jemalloc-4.0.4.tar.bz2 cd jemalloc-4.0.4 ./autogen.sh make && make install echo '/usr/local/lib' >> /etc/ld.so.conf.d/local.conf ldconfig
二、下载二进制包并部署： cd /opt/soft wget http://repositories.voole.com/Percona-Server-5.7.21-20-Linux.x86_64.ssl101.tar.gz tar zxvf Percona-Server-5.7.21-20-Linux.x86_64.ssl101.tar.gz mv Percona-Server-5.7.21-20-Linux.x86_64.ssl101 /usr/local/mysql
三、创建mysql用户组 groupadd mysql && useradd -g mysql -M -s /sbin/nologin mysql
四、创建数据库文件my.cnf ，统一放到程序目录里 mv /etc/my.cnf /etc/my.cnf.bak SSD固态盘：wget http://repositories.voole.com/my57_19.cnf -O /etc/my.cnf SATA磁盘：wget http://repositories.voole.com/my57_19_sata.cnf -O /etc/my.cnf 从库：wget http://repositories.voole.com/my_slave.cnf -O /etc/my.cnf 主库：wget http://repositories.voole.com/my_master.cnf -O /etc/my.cnf
五、初始化，记得加上配置文件 /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize
六、设置环境变量 echo "export PATH=/usr/local/mysql/bin:$PATH">>/etc/profile && source /etc/profile which mysql
七、修改属主属组 chown -R mysql.mysql /opt/mysql_data
八、启动mysql5.7服务 cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql chmod 755 /etc/init.d/mysql /etc/init.d/mysql start
九、重置密码（mysql5.7和其他版本不同、初次安装会生成一个随机密码在/opt/mysql_data/logerr.err日志内） 密码在logerr.err 中会默认生成一个
set password=password('123456'); 如果需要再次修改root密码 update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';
十、设置访问权限
grant all on . to root@"%" identified by "mysql*()";
