三、初始化
1.创建用户和datadir目录
groupadd mysql
useradd -m -d /home/mysql -g mysql mysql
su - mysql
mkdir data
2.初始化my.cnf
[root@TPCC2 ~]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/home/mysql/data
socket=/home/mysql/data/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-error=/home/mysql/data/mysqld.log
pid-file=/home/mysql/data/mysqld.pid
3.初始化数据库
mysqld --initialize --user=mysql
默认使用/etc/my.cnf
[mysql@localhost data]$ pwd
/home/mysql/data
[mysql@localhost data]$ ll
total 110624
-rw-r-----. 1 mysql mysql 56 Oct 23 12:59 auto.cnf
-rw-r-----. 1 mysql mysql 407 Oct 23 12:59 ib_buffer_pool
-rw-r-----. 1 mysql mysql 12582912 Oct 23 12:59 ibdata1
-rw-r-----. 1 mysql mysql 50331648 Oct 23 12:59 ib_logfile0
-rw-r-----. 1 mysql mysql 50331648 Oct 23 12:59 ib_logfile1
drwxr-x---. 2 mysql mysql 4096 Oct 23 12:59 mysql
-rw-r-----. 1 mysql mysql 991 Oct 23 12:59 mysqld.log
drwxr-x---. 2 mysql mysql 4096 Oct 23 12:59 performance_schema
drwxr-x---. 2 mysql mysql 12288 Oct 23 12:59 sys
4.临时密码
查找初始用户、密码
[mysql@localhost data]$ grep "A temporary password" mysqld.log
2015-10-23T04:59:09.504285Z 1 [Note] A temporary password is generated for root@localhost: BdwK<Crzy08g
四、启动
[mysql@localhost ~]$ mysqld_safe --user=mysql &
[1] 11255
[mysql@localhost ~]$ 151023 13:01:37 mysqld_safe Logging to '/home/mysql/data/mysqld.log'.
151023 13:01:37 mysqld_safe Starting mysqld daemon with databases from /home/mysql/data

五、登陆并修改临时密码
[mysql@TPCC2 ~]$ mysql -u root -h localhost -p -S /home/mysql/data/mysql.sock
Enter password:

六、测试
1.新密码登陆
[mysql@localhost ~]$ mysql -u root -h localhost -S /home/mysql/data/mysql.sock -pmysql
mysql: [Warning] Using a password on the command line interface can be insecure.
