安裝環境
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：對於多核CPU、固態硬盤、鎖有着更好的優化，每秒100W QPS已不再是MySQL的追求，下個版本能否上200W QPS才是吾等用戶更關心的
- 更好的InnoDB存儲引擎
- 更為健壯的復制功能：復制帶來了數據完全不丟失的方案，傳統金融客戶也可以選擇使用MySQL數據庫。此外，GTID在線平滑升級也變得可能
- 更好的優化器：優化器代碼重構的意義將在這個版本及以后的版本中帶來巨大的改進，Oracle官方正在解決MySQL之前最大的難題
- 原生JSON類型的支持
- 更好的地理信息服務支持：InnoDB原生支持地理位置類型，支持GeoJSON，GeoHash特性
- 新增sys庫：以后這會是DBA訪問最頻繁的庫
步驟一
創建mysql用戶組及用戶：
groupadd mysql useradd -r -g mysql mysql
創建數據庫相關目錄：
mkdir -p /home/program/mysql mkdir -p /home/data mkdir -p /home/data/mysql
步驟二
解壓
tar xzf boost_1_59_0.tar.gz tar xzf mysql-5.7.12.tar.gz
預編譯
cmake . -DCMAKE_INSTALL_PREFIX=/home/program/mysql \ -DMYSQL_DATADIR=/home/data/mysql \ -DDOWNLOAD_BOOST=1 \ #從MySQL 5.7.5開始Boost庫是必需的 -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
編譯安裝
mark mark install 注意：如果需要重裝mysql，在/home/software/mysql-5.7.12再執行下make install就可以了，不需要再cmake和make
步驟三
清除安裝臨時文件
make clean
修改目錄擁有者
chown -Rf mysql:mysql /home/program/mysql chown -Rf mysql:mysql /home/data/mysql
配置啟動文件
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，僅供參考

初始化數據庫
注：
- 之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目錄下,且已被廢棄
- "--initialize"會生成一個隨機密碼(~/.mysql_secret)，而"--initialize-insecure"不會生成密碼
- --datadir目標目錄下不能有數據文件
/home/program/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/home/program/mysql --datadir=/home/data/mysql配置環境變量
mysql_home=/usr/local/mysql PATH=$PATH:$mysql_home/bin
source /etc/profile
