1.簡介

采用yum安裝lamp簡單，快捷，在工作中也得到了普遍應用。但是如果我們需要某些特定模塊功能，以及制定安裝位置等，就需要用到編譯安裝了，接下來將編譯安裝lamp之mysql. mysql的簡介網上已經有很多材料，這裏就不再贅述，註重演示如何安裝mysql.

2.系統環境及服務版本

centos7.5

服務器IP:172.20.10.7/28

mysql-5.5.33

3.上傳mysql安裝包並解壓

[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

4.移動解壓包至/usr/local/目錄之下

[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  #對這個包做一個軟連接名為mysql

5.創建用戶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用戶來運行mysql

6.創建數據庫數據目錄

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

7.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
...

8.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行左右添加剛才創建的數據保存路徑
 41 
 42 # Don‘t listen on a TCP/IP port at all. This can be     a security enhancement,
...

9. 生成mysql的服務管理腳本

[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

10.啟動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      50                               *:3306                                         *:*                  
LISTEN      0      128                              *:22                                           *:*                  
LISTEN      0      100                      127.0.0.1:25                                           *:*                  
LISTEN      0      128                             :::22                                          :::*                  
LISTEN      0      100                            ::1:25                                          :::*    

11.導出二進制程序

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

12.登錄mysql

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