MySql5.7.25源码安装记录

在官网：http://dev.mysql.com/downloads/mysql/ 中下载要安装的版本的数据库：

mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

解压

tar -zxvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

移动并修改文件名

#mv /data/software/mysql-5.7.25-linux-glibc2.12-x86_64 /usr/local/mysql

创建数据存放目录

#mkdir /data/mysql5.7_3306 

新建mysql用户、组及目录

#useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql

改变目录属有者

#cd /usr/local/mysql
#chown -R mysql .
#chgrp -R mysql .

初始化数据库

#bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql5.7_3306

记录下初始密码：:+uJDQDtF6/u

#bin/mysql_ssl_rsa_setup --datadir=/data/mysql5.7_3306

修改系统配置文件（ 5.7.18开始后面的版本没有my-default.cnf 需要的可以复制以前的my.cnf文件）

cd /usr/local/mysql/support-files

#复制启动文件
# cp mysql.server /etc/init.d/mysql
# vim /etc/init.d/mysql

# vim /etc/init.d/mysql   修改文件存放路径

basedir=/usr/local/mysql
datadir=/data/mysql5.7_3306

 

从别的地方复制了一个5.5.59的my.cnf放到了/etc目录下，启动mysql /etc/init.d/mysql start 报错

查看日志发现（/data/mysql5.7_3306/localhost.localdomain.err）

thread_concurrency 这个变量提示未定义，mysql在5.7.2后废除了这个配置，删掉后重新启动

登录

mysql -hlocalhost -uroot -p  

如果出现：-bash: mysql: command not found

就执行： # ln -s /usr/local/mysql/bin/mysql /usr/bin

没有出现就不用执行
 

修改密码
mysql>set password for [email protected] = password('123456'); 
mysql>flush privileges; 

设置root账户可以被远程登录
mysql>grant all privileges on *.* TO'root'@'%' identified by 'root' with grant option; 
mysql>flush privileges;

修改密码
mysql>set password for [email protected]'%'= password('123456'); 
mysql>flush privileges; 

查看表
mysql> use mysql;
mysql> select host,user from user;

配置mysql自动启动

# chmod 755 /etc/init.d/mysql
# chkconfig --add mysql
# chkconfig --level 345 mysql on

复制的5.5.59版本的my.cnf

# Example MySQL config file for large systems.
#
# This is for a large system with memory = 512M where the system runs mainly
# MySQL.
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients

#password	= your_password

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
