Centos6.6安装通用二进制版mysql5.6.38

安装过程中的命令

[root@host3 mysql_5.6.38]# groupadd mysql #创建用户组
[root@host3 mysql_5.6.38]# useradd -r -g mysql -s /bin/false mysql #创建用户mysql且指定组为mysql
[root@host3 mysql_5.6.38]# tar -zxvf mysql-5.6.38-linux-glibc2.12-x86_64.tar.gz -C /usr/local/ #解压文件至/usr/local目录下
[root@host3 mysql_5.6.38]# mv mysql-5.6.38-linux-glibc2.12-x86_64/ mysql_5.6.38 #重命名
[root@host3 mysql_5.6.38]# cd /usr/local/mysql_5.6.38 #进入安装目录
[root@host3 mysql_5.6.38]# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql_5.6.38 --datadir=/data/mysql #运行安装数据库脚本,perl脚本.
[root@host3 mysql_5.6.38]# bin/mysqld_safe --user=mysql &
# Next command is optional
[root@host3 mysql_5.6.38]# vi support-files/mysql.server #修改basedir和datadir的值为安装时的设定值,若安装目录为/usr/local/mysql则不需要修改,系统模式数据放在/var/lib/mysql目录
[root@host3 mysql_5.6.38]# cp support-files/mysql.server /etc/init.d/mysql #拷贝至可用于service 启动,文件名就是server后面的服务
[root@host3 mysql_5.6.38]# service mysql start #启动服务器
[root@host3 mysql_5.6.38]# ./bin/mysqladmin -u root password '123456' #设置密码为123456

安装之后的服务器默认是空密码,即无密码

操作系统信息

[root@host3 mysql_5.6.38]# cat /proc/version

[root@host3 mysql_5.6.38]# cat /etc/issue

安装过程中遇到的问题

没有安装perl

[root@host3 scripts]# ./mysql_install_db –user=mysql

-bash: ./mysql_install_db: /usr/bin/perl: bad interpreter: No such file or directory

[root@host3 scripts]# yum -y install perl perl-devel

找不到libnuma.so.1库,因为是64位系统,故安装numactl.x86_64

[root@host3 mysql_5.6.38]# ./scripts/mysql_install_db –user=mysql

Installing MySQL system tables…./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

Answer：

yum -y install numactl.x86_64

安装的实际过程输出

mysql服务安装过程,该阶段必须要有my.cnf文件指定mysql数据的存储位置，否则会将数据文件默认安装到/var/lib/mysql目录

[root@host3 mysql_5.6.38]# ./scripts/mysql_install_db --user=mysql

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h host3 password 'new-password'

Alternatively you can run:

./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

WARNING: Found existing config file ./my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as ./my-new.cnf,
please compare it with your file and take the changes you need.

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
