CentOS MySQL 5.7编译安装步骤详细说明_Centos

CentOS　MySQL 5.7编译安装

MySQL 5.7 GA版本的发布，也就是说从现在开始5.7已经可以在生产环境中使用，有任何问题官方都将立刻修复。

MySQL 5.7主要特性：

更好的性能：对于多核CPU、固态硬盘、锁有着更好的优化，每秒100W QPS已不再是MySQL的追求，下个版本能否上200W QPS才是吾等用户更关心的
更好的InnoDB存储引擎
更为健壮的复制功能：复制带来了数据完全不丢失的方案，传统金融客户也可以选择使用MySQL数据库。此外，GTID在线平滑升级也变得可能
更好的优化器：优化器代码重构的意义将在这个版本及以后的版本中带来巨大的改进，Oracle官方正在解决MySQL之前最大的难题
原生JSON类型的支持
更好的地理信息服务支持：InnoDB原生支持地理位置类型，支持GeoJSON，GeoHash特性
新增sys库：以后这会是DBA访问最频繁的库

MySQL 5.7已经作为数据库可选项添加到《OneinStack》

安装依赖包

									wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.11.tar.gz

添加mysql用户

				?

									useradd -M -s /sbin/nologin mysql

预编译

				?

									tar xzf boost_1_59_0.tar.gz

									tar xzf mysql-5.7.11.tar.gz

									mkdir -p /data/mysql

									cd mysql-5.7.11

									cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

									-DMYSQL_DATADIR=/data/mysql \

编译安装

				?

									make -j `grep processor /proc/cpuinfo | wc -l` #编译很消耗系统资源，小内存可能编译通不过

									make install

启动脚本，设置开机自启动

				?

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

									chmod +x /etc/init.d/mysqld

									chkconfig --add mysqld

									chkconfig mysqld on

初始化数据库

注：

之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃
"--initialize"会生成一个随机密码(~/.mysql_secret)，而"--initialize-insecure"不会生成密码
--datadir目标目录下不能有数据文件

启动数据库

				?

									/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

设置数据库密码

				?

									dbrootpwd=oneinstack #数据库root密码

									/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'127.0.0.1' identified by \"$dbrootpwd\" with grant option;"

									/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'localhost' identified by \"$dbrootpwd\" with grant option;"
