(2)编译安装lamp三部曲之mysql-技术流ken

1.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.

2.系统环境及服务版本

centos7.5

服务器IP:172.20.10.7/28

mysql-5.5.33

3.上传mysql安装包并解压

[[email protected] ~]# rz
[[email protected] ~]# ls
mysql-5.5.33-linux2.6-x86_64.tar.gz
[[email protected] ~]# tar xf mysql-5.5.33-linux2.6-x86_64.tar.gz

4.移动解压包至/usr/local/目录之下

[[email protected] ~]# mv mysql-5.5.33-linux2.6-x86_64 /usr/local[[email protected] ~]# cd /usr/local
[[email protected] local]# ls
bin    include  libexec                       share
etc    lib      mysql-5.5.33-linux2.6-x86_64  src
games  lib64    sbin
[[email protected] 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

5.创建用户mysql

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

6.创建数据库数据目录

[[email protected] mysql]# mkdir /ken
[[email protected] mysql]# chown -R mysql.mysql /ken 

7.初始化mysql

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

8.生成mysql的配置文件

[[email protected] scripts]# cd ..
[[email protected] mysql]# cd support-files/
[[email protected] support-files]# cp my-huge.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
[[email protected] 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,
...

9. 生成mysql的服务管理脚本

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

10.启动mysql

[[email protected] support-files]# systemctl start mysqld
[[email protected] support-files]# ss -tnl
State       Recv-Q Send-Q               Local Address:Port                              Peer Address:Port
LISTEN      0      50                               *:3306                                         *:*
LISTEN      0      128                              *:22                                           *:*
LISTEN      0      100                      127.0.0.1:25                                           *:*
LISTEN      0      128                             :::22                                          :::*
LISTEN      0      100                            ::1:25                                          :::*    

11.导出二进制程序

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

12.登录mysql

[[email protected] support-files]# mysql -uroot -p
