【Linux】Mysql5.7.12源码编译安装及配置

安装环境

　　Linux（CentOS7.0 版）、boost_1_59_0.tar.gz、mysql-5.7.12.tar.gz

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

步骤一

   创建mysql用户组及用户：

groupadd mysql
useradd -r -g mysql mysql

   创建数据库相关目录：

mkdir -p /home/program/mysql
mkdir -p /home/data
mkdir -p /home/data/mysql

步骤二

   解压

tar xzf boost_1_59_0.tar.gz 
tar xzf mysql-5.7.12.tar.gz 

   预编译

cmake . -DCMAKE_INSTALL_PREFIX=/home/program/mysql 
-DMYSQL_DATADIR=/home/data/mysql 
-DDOWNLOAD_BOOST=1    #从MySQL 5.7.5开始Boost库是必需的
-DWITH_BOOST=/home/software/boost_1_59_0 
-DSYSCONFDIR=/etc 
-DWITH_INNOBASE_STORAGE_ENGINE=1 
-DWITH_PARTITION_STORAGE_ENGINE=1 
-DWITH_FEDERATED_STORAGE_ENGINE=1 
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 
-DWITH_MYISAM_STORAGE_ENGINE=1 
-DENABLED_LOCAL_INFILE=1 
-DENABLE_DTRACE=0 
-DDEFAULT_CHARSET=utf8mb4 
-DDEFAULT_COLLATION=utf8mb4_general_ci 
-DWITH_EMBEDDED_SERVER=1

   编译安装

mark
mark install
注意：如果需要重装mysql，在/home/software/mysql-5.7.12再执行下make install就可以了，不需要再cmake和make

步骤三

   清除安装临时文件

make clean

   修改目录拥有者

chown -Rf mysql:mysql /home/program/mysql
chown -Rf mysql:mysql /home/data/mysql

   配置启动文件

cp /home/program/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
service mysql start

/etc/my.cnf，仅供参考

初始化数据库

注：

1. 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
2. "--initialize"会生成一个随机密码(~/.mysql_secret)，而"--initialize-insecure"不会生成密码
3. --datadir目标目录下不能有数据文件

/home/program/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/home/program/mysql --datadir=/home/data/mysql

   配置环境变量

mysql_home=/usr/local/mysql
PATH=$PATH:$mysql_home/bin

source /etc/profile
