mysql数据库安装及配置
安装前的准备
yum install \ vim \ git \ gcc \ gcc-c++ \ wget \ make \ cmake \ automake \ autoconf \ libaio \ libtool \ net-tools \ bison-devel \ libaio-devel \ ncurses-devel \ perl-Data-Dumper \ -y下载boost_1_59_0
cd /usr/local wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz下载mysql-5.7.18
cd /root wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18.tar.gz tar -zxvf mysql-5.7.18.tar.gz cd mysql-5.7.18运行cmake
cmake . \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DWITH_SYSTEMD=1 \ -DDOWNLOAD_BOOST=1 \ -DWITH_BOOST=/usr/local \ -DDEFAULT_CHARSET=utf8mb4 \ make make install添加mysql用户
useradd -s /sbin/nologin -M mysql创建数据文件目录、所属组、用户改为mysql
mkdir /data/ mkdir /data/mysql/ chown -R mysql:mysql /etc/my.cnf chown -R mysql:mysql /data/mysql/ chown -R mysql:mysql /var/*/mysql* chown -R mysql:mysql /usr/local/mysql/修改SELinux

exit cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/mysqld.service详细配置

systemctl enable mysqld systemctl start mysqld systemctl daemon-reload测试配置是否正确，没有任何输出则表示一切正常
/usr/local/mysql/bin/mysqld_pre_systemd数据文件所属用户修改为mysql（如果‘初始化数据库配置’时完全按文档进行，可不执行本步骤，不确定则执行）
chown -R mysql:mysql /data/mysql/启动mysql
systemctl enable mysqld systemctl start mysqld添加mysql到mysql用户环境变量
su mysql vim /home/mysql/.bash_profile PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/mysql/bin ESC :wq source /home/mysql/.bash_profile尝试连接mysql
