scripts/mysql_install_db --basedir=/opt/data/mysql/ --datadir=/opt/data/var/ --user=mysql  #初始化

bin/mysqld_safe --user=mysql &  #启动

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

service mysql start  --启动MySQL

注：在启动MySQL服务时，会按照一定次序搜索my.cnf，先在/etc目录下找，找不到则会搜索"$basedir/my.cnf"，在本例中就是 /usr/local/mysql/my.cnf，这是新版MySQL的配置文件的默认位置！

注意：在CentOS 6.4版操作系统的最小安装完成后，在/etc目录下会存在一个my.cnf，需要将此文件更名为其他的名字，如：/etc/my.cnf.bak，否则，该文件会干扰源码安装的MySQL的正确配置，造成无法启动。

在使用"yum update"更新系统后，需要检查下/etc目录下是否会多出一个my.cnf，如果多出，将它重命名成别的。否则，MySQL将使用这个配置文件启动，可能造成无法正常启动等问题。

二进制安装mysql 5.6

tar xf mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz 

ln -sv mysql-5.6.29-linux-glibc2.5-x86_64 mysql

useradd -r -s /sbin/nologin -M  mysql

chown mysql.mysql mysql-5.6.29-linux-glibc2.5-x86_64 -R 

cd scripts/

./mysql_install_db --basedir=/opt/mysql --datadir=/opt/mysql/data/ --user=mysql

./bin/mysqld_safe --defaults-file=my.cnf &

netstat -tnulp

二进制安装mysql 5.7

shell> groupadd mysql

shell> useradd -r -g mysql -s /bin/false mysql

shell> cd /usr/local

shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz

shell> ln -s full-path-to-mysql-VERSION-OS mysql

shell> cd mysql

shell> mkdir mysql-files

shell> chmod 770 mysql-files

shell> chown -R mysql .

shell> chgrp -R mysql .

shell> bin/mysql_install_db --user=mysql    # Before MySQL 5.7.6

shell> bin/mysqld --initialize --user=mysql # MySQL 5.7.6 and up

shell> bin/mysql_ssl_rsa_setup              # MySQL 5.7.6 and up

shell> chown -R root .

shell> chown -R mysql data mysql-files

shell> bin/mysqld_safe --user=mysql &

初始化数据库，注意密码

./bin/mysqld --initialize  --basedir=/opt/mysql7/ --datadir=/opt/mysql7/data/ --user=mysql

./bin/mysqld_safe --user=mysql &

# ./bin/mysqladmin -u root -p password "wqh"

mysql>  alter user ‘root‘@‘localhost‘ identified by ‘mysql‘;

mysql> flush privileges;
