mysql 5.7數據庫安裝部署

 1、安裝依賴環境：

 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

 2、下載二進制包並部署：
 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

 3、建立mysql用戶組
 groupadd mysql && useradd -g mysql -M -s /sbin/nologin mysql

 4、建立數據庫文件my.cnf ，統一放到程序目錄裏
 mv /etc/my.cnf /etc/my.cnf.bak
 SSD固態盤：wget http://repositories.voole.com/my57_19.cnf -O /etc/my.cnf
 SATA磁盤：wget http://repositories.voole.com/my57_19_sata.cnf -O /etc/my.cnf
 從庫：wget http://repositories.voole.com/my_slave.cnf -O /etc/my.cnf
 主庫：wget http://repositories.voole.com/my_master.cnf -O /etc/my.cnf

 5、初始化，記得加上配置文件
 /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize

 6、設置環境變量
 echo "export PATH=/usr/local/mysql/bin:$PATH">>/etc/profile && source /etc/profile
 which mysql

 7、修改屬主屬組
 chown -R mysql.mysql /opt/mysql_data

 8、啓動mysql5.7服務
 cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
 chmod 755 /etc/init.d/mysql
 /etc/init.d/mysql start

 9、重置密碼（mysql5.7和其餘版本不一樣、初次安裝會生成一個隨機密碼在/opt/mysql_data/logerr.err日誌內）
 密碼在logerr.err 中會默認生成一個
 >set password=password('123456');
 若是須要再次修改root密碼
 update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';

10、設置訪問權限

grant all on *.* to root@"%" identified by "mysql*()";
