tar -zxvf MySQL-5.7.23-linux-glibc2.12-x86_64.tar.gz

創(chuàng)建mysql目錄：

mkdir -p /data/mysql
cd /data/mysql/

binlog存儲(chǔ)目錄：

mkdir binlog

mysql數(shù)據(jù)目錄：

mkdir data

mysql日志目錄：

mkdir log

限制mysql導(dǎo)入導(dǎo)出目錄：

mkdir tmp

授權(quán)mysql用戶(hù)：

chown -R mysql:mysql /data/mysql/

移動(dòng)目錄到自定義的位置，這里存放位置為/usr/local下：

mv mysql-5.7.23-linux-glibc2.12-x86_64 /usr/local/mysql

cd /usr/local/

程序目錄授權(quán)：

chown -R mysql:mysql /usr/local/mysql/

備份自帶的配置文件：

cp my.cnf my.cnf.back

編輯新的配置文件：

vi my.cnf

保存退出

cd /usr/local/mysql/

初始化數(shù)據(jù)庫(kù)：

./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysql/data/

cd /data/mysql/log/

查看日志，初始化會(huì)生成初始密碼：

tail -f error.log

拷貝啟動(dòng)腳本到系統(tǒng)啟動(dòng)目錄：

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

加入開(kāi)機(jī)啟動(dòng)服務(wù)：

chkconfig --add mysql

設(shè)置開(kāi)機(jī)啟動(dòng)：

chkconfig mysql on

拷貝命令到系統(tǒng)路徑下，便于全局調(diào)用：

cp /usr/local/mysql/bin/* /usr/local/sbin/

/etc/init.d/mysql start ##啟動(dòng)數(shù)據(jù)庫(kù)

登錄到數(shù)據(jù)庫(kù)內(nèi)修改root用戶(hù)的初始化密碼：

mysql -u root -p --->輸入mysql數(shù)據(jù)庫(kù)root用戶(hù)的密碼
SET PASSWORD = PASSWORD('新密碼'); ##修改root用戶(hù)的密碼。（alter user user() identified by '新密碼';）

到這里整個(gè)初始化過(guò)程就完成了。
