原始碼包安裝Mysql
前期準備
mkdir /usr/local/src/mysql5.7.10-glibc
cd /usr/local/src/mysql5.7.10-glibc
#下載mysql包
wget https://mirrors.aliyun.com/mysql/MySQL-5.7/mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz

開始安裝
關閉防火牆
systemctl stop firewalld
setenforce 0
建立使用者
groupadd mysql && useradd -M -g mysql -s /sbin/nologin mysql
安裝依賴
yum install -y libaio.x86_64
刪除已存在檔案
mv /etc/my.cnf /etc/my.cnf.bak
建立資料存放資料夾
mkdir /home/mysqldata && mkdir /home/mysqlbinloginfo
拷貝檔案
cd /usr/local/src/mysql5.7.10-glibc && cp -f /usr/local/src/mysql5.7.10-glibc/my.cnf /etc/my.cnf
解壓
tar -xvf mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz -C /usr/local && mv /usr/local/mysql-5.7.10-linux-glibc2.5-x86_64 /usr/local/mysql
授權檔案許可權
chown -R mysql:mysql /usr/local/mysql/* /home/mysqldata /home/mysqlbinloginfo && chmod -R 755 /home/mysqldata
安裝
cd /usr/local/mysql/bin && ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysqldata
拷貝啟動檔案
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld && sed -i '47 c\datadir=/home/mysqldata' /etc/init.d/mysqld
新增環境變數
echo -e "export PATH=/usr/local/mysql/bin:\$PATH" > /etc/profile.d/mysql.sh
設定自啟
chkconfig --add mysqld && chkconfig mysqld on && systemctl start mysqld
檢視初始密碼
mima=`cat /root/.mysql_secret | sed -n '2p'`
設定新密碼
mysqlpw=*hy7uBHf6
生效系統檔案
source /etc/profile
修改初始密碼（按要求必須修改初始密碼）
mysql -uroot -p$mima --connect-expired-password -e "alter user 'root'@'localhost' identified by '${mysqlpw}';flush privileges;"
