mysql 5.7已經作為資料庫可選項新增到《oneinstack》
安裝依賴包
yum -y install gcc gcc-c++ ncurses ncurses-devel cmake
cd /root/oneinstack/src
wget
wget
新增mysql使用者
useradd -m -s /sbin/nologin mysql
預編譯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 \
-ddownload_boost=1 \ #從mysql 5.7.5開始boost庫是必需的

編譯安裝
make -j `grep processor /proc/cpuinfo | wc -l` #編譯很消耗系統資源，小記憶體可能編譯通不過
make install
啟動指令碼，設定開機自啟動

初始化資料庫
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"會生成乙個隨機密碼(~/.mysql_secret)，而"--initialize-insecure"不會生成密碼
--datadir目標目錄下不能有資料檔案
啟動資料庫
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
設定資料庫密碼
dbrootpwd=oneinstack #資料庫root密碼
/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;"
