MySQL安装文档
1. 安装依赖包
yum install -y autoconf automake imake libxml2-devel expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel numactl
2. 安装MySQL软件
mv /etc/my.cnf /etc/my.cnf.`date +%Y%m%d%H%M%S`.bak
cd /usr/local/src
tar zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.19-linux-glibc2.12-x86_64 /usr/local/mysql
groupadd mysql -g 512
useradd -u 512 -g mysql -s /sbin/nologin -d /home/mysql mysql
mkdir -p /data/mysql
mkdir -p /data/slowlog
chown -R mysql:mysql /data/mysql
chown -R mysql:mysql /usr/local/mysql
chown -R mysql:mysql /data/slowlog
mkdir -p /var/run/mysql
chown mysql:mysql /var/run/mysql
3. 配置MySQL

4. 初始化MySQL
/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --datadir=/data/mysql --basedir=/usr/local/mysql --initialize-insecure
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod 700 /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
cat >> /etc/ld.so.conf.d/mysql-x86_64.conf<<EOF
/usr/local/mysql/lib
EOF
ldconfig
if [ -d "/proc/vz" ];then
ulimit -s unlimited
fi
/etc/init.d/mysqld start
cat >> /etc/profile <<EOF
export PATH=$PATH:/usr/local/mysql/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/mysql/lib
EOF
5. 配置数据库密码
/usr/local/mysql/bin/mysqladmin -u root password 密码
cat > /tmp/mysql_sec_script<<EOF
use mysql;
delete from mysql.user where user!='root' or host!='localhost';
#grant all privileges on *.* to 'sys_admin'@'%' identified by '123456';
flush privileges;
EOF
/usr/local/mysql/bin/mysql -u root -p -h localhost < /tmp/mysql_sec_script
rm -f /tmp/mysql_sec_script
/etc/init.d/mysqld restart
