(2)编译安装lamp三部曲之mysql-技术流ken

简介

采用yum安装lamp简单，快捷，在工作中也得到了普遍应用。但是如果我们需要某些特定模块功能，以及制定安装位置等，就需要用到编译安装了，接下来将编译安装lamp之mysql. mysql的简介网上已经有很多材料，这里就不再赘述，注重演示如何安装mysql.

系统环境及服务版本

centos7.5

服务器IP:172.20.10.7/28

mysql-5.5.33

上传mysql安装包并解压

[root@ken ~]# rz
[root@ken ~]# ls
mysql-5.5.33-linux2.6-x86_64.tar.gz
[root@ken ~]# tar xf mysql-5.5.33-linux2.6-x86_64.tar.gz

移动解压包至/usr/local/目录之下

[root@ken ~]# mv mysql-5.5.33-linux2.6-x86_64 /usr/local
[root@ken ~]# cd /usr/local
[root@ken local]# ls
bin    include  libexec                       share
etc    lib      mysql-5.5.33-linux2.6-x86_64  src
games  lib64    sbin
[root@ken local]# ln -s mysql-5.5.33-linux2.6-x86_64 mysql  #对这个包做一个软连接名为mysql

创建用户mysql

[root@ken local]# groupadd -r mysql
[root@ken local]# useradd -g mysql -r -s /sbin/nologin mysql
[root@ken local]# cd mysql
[root@ken mysql]# chown -R mysql.mysql ./*  #以mysql用户来运行mysql

创建数据库数据目录

[root@ken mysql]# mkdir /ken
[root@ken mysql]# chown -R mysql.mysql /ken 

初始化mysql

[root@ken mysql]# cd scripts
[root@ken scripts]# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/ken --user=mysql
Installing MySQL system tables...
OK
Filling help tables...
OK

生成mysql的配置文件

[root@ken scripts]# cd ..
[root@ken mysql]# cd support-files/
[root@ken support-files]# cp my-huge.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
[root@ken support-files]# vim /etc/my.cnf
 ...
33 read_buffer_size = 2M
 34 read_rnd_buffer_size = 8M
 35 myisam_sort_buffer_size = 64M
 36 thread_cache_size = 8
 37 query_cache_size = 32M
 38 # Try number of CPU's*2 for thread_concurrency
 39 thread_concurrency = 8
 40 datadir=/ken               #40行左右添加刚才创建的数据保存路径
 41 
 42 # Don't listen on a TCP/IP port at all. This can be     a security enhancement,
...

生成mysql的服务管理脚本

[root@ken support-files]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@ken support-files]# chkconfig --add mysqld
[root@ken support-files]# chkconfig mysqld on

启动mysql

[root@ken support-files]# systemctl start mysqld
[root@ken support-files]# ss -tnl
State       Recv-Q Send-Q               Local Address:Port                              Peer Address:Port

LISTEN      0      128                             :::22                                          :::*                  
LISTEN      0      100                            ::1:25                                          :::*    

导出二进制程序

[root@ken support-files]# vim /etc/profile.d/mysql.sh
  export PATH=$PATH:/usr/local/mysql/bin
[root@ken support-files]# source /etc/profile

登录mysql

[root@ken support-files]# mysql -uroot -p
