CentOS下MySQL 5.6编译安装

卸载mariadb

[root@localhost ~]# yum -y remove mariadb-libs

安装依赖

[root@localhost ~]#  yum -y install gcc gcc-c++ cmake ncurses-devel autoconf perl perl-devel

创建mysql安装目录以及数据存放目录

[root@localhost ~]# mkdir /usr/local/mysql
[root@localhost ~]# mkdir /usr/local/mysql/data

创建用户、用户组

[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -r -g mysql mysql

下载源码包

[root@localhost src]# wget https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.35.tar.gz
[root@localhost src]# tar -zxvf mysql-5.6.35.tar.gz
[root@localhost src]# cd mysql-5.6.35
[root@localhost mysql-5.6.35]# 
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DINSTALL_DATADIR=/usr/local/mysql/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_USER=mysql \
-DMYSQL_TCP_PORT=3306

CMAKE参数说明：

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql //默认安装目录

-DINSTALL_DATADIR=/usr/local/mysql/data //数据库存放目录

-DDEFAULT_CHARSET=utf8 　　　 //使用utf8字符

-DDEFAULT_COLLATION=utf8_general_ci //校验字符

-DEXTRA_CHARSETS=all 　　//安装所有扩展字符集

-DENABLED_LOCAL_INFILE=1 　　//允许从本地导入数据

-DMYSQL_USER=mysql

-DMYSQL_TCP_PORT=3306

CMAKE详细配置请参照mysql官网

编译安装

[root@localhost mysql-5.6.35]# make
[root@localhost mysql-5.6.35]# make install
[root@localhost mysql-5.6.35]# echo $?
0

设置目录权限

[root@localhost mysql-5.6.35]# cd /usr/local/mysql
[root@localhost mysql]# chown -R mysql:mysql .
[root@localhost mysql]# chown -R mysql:mysql data

chown 命令 更改某个文件或目录的属主和属组。

-R : 递归式地改变指定目录及其下的所有子目录和文件的拥有者。

-v : 显示chown命令所做的工作。

将mysql的启动服务添加到系统服务中

[root@localhost mysql]# cd /usr/local/mysql
[root@localhost mysql]# cp support-files/my-default.cnf /etc/my.cnf

初始化

[root@localhost mysql]# cd /usr/local/mysql
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql

看到有两个OK说明成功了

配置环境变量（在文件最后面添加）

[root@localhost mysql]# vim /etc/profile
export MYSQL_HOME="/usr/local/mysql"
export PATH="$PATH:$MYSQL_HOME/bin"
[root@localhost mysql]# source /etc/profile

将mysql加入到可控制启动的服务的文件夹内，并命名mysql，即service可控制的服务名，至此可用service mysql start控制启动mysql

/etc/init.d 是/etc/rc.d/init.d的链接，在/etc/init.d添加一个文件会同步在/etc/rc.d/init.d下添加一个相同文件

[root@localhost mysql]# cd /usr/local/mysql/
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysql

chkconfig命令主要用来更新（启动或停止）和查询系统服务的运行级信息。谨记chkconfig不是立即自动禁止或激活一个服务，它只是简单的改变了符号连接

–add : 加所指定的系统服务，让chkconfig指令得以管理它，并同时在系统启动的叙述文件内增加相关数据。服务脚本必须存放在/etc/ini.d/目录下

让mysql服务加入到开机启动指令管理的服务列表中

chkconfig –add mysql

开机自启动mysql服务

on : 针对的服务有等级限制，具体查询chkconfig详细

[root@localhost mysql]# chkconfig --add mysql
[root@localhost mysql]# chkconfig mysql on
[root@localhost mysql]# service mysql start
Starting MySQL.Logging to '/usr/local/mysql/data/localhost.localdomain.err'.
 SUCCESS! 
[root@localhost mysql]#

给MySQL设置密码(敲击回车输入密码即可）

[root@localhost mysql]# mysqladmin -u root password
New password: 
Confirm new password:

为root添加远程连接

[root@localhost mysql]# mysql -uroot -p123456
