CentOS7.5源码编译安装mysql5.7.29

#查看系统版本

[root@ctos3 ~]# cat /etc/redhat-release

CentOS Linux release 7.5. (Core)

#下载源码包，需要注意的是mysql5.7 编译安装需要boost 库，可以在官网下载含boost的源码包

https://dev.mysql.com/downloads/mysql/5.7.html#downloads

#提示，下载的时候如果不想进行登录或注册，就点不用，开始下载

#开始源码编译安装

#1.安装相关依赖包

yum install -y gcc gcc-c++ cmake ncurses ncurses-devel bison wget openssl-devel.x86_64

#2.创建用户和组

groupadd  mysql

useradd mysql -s /sbin/nologin -M -g mysql

#3.下载mysql和解压,也可以下载好使用rz(包名lrzsz)上传

mkdir /home/demo/tools/

cd /home/demo/tools/
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.29.tar.gz
tar xf mysql-boost-5.7.29.tar.gz

#4.配置相关参数

[root@ctos3 tools]# cd mysql-5.7./

[root@ctos3 mysql-5.7.]# pwd

/home/demo/tools/mysql-5.7.

[root@ctos3 mysql-5.7.29]# cmake -DCMAKE_INSTALL_PREFIX=/application/mysql  -DMYSQL_DATADIR=/application/mysql/data -DMYSQL_UNIX_ADDR=/application/mysql/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost

#参数介绍

DCMAKE_INSTALL_PREFIX  #指定MySQL程序的安装目录

DMYSQL_DATADIR         #数据文件目录

DMYSQL_UNIX_ADDR       #socket文件路径

DDEFAULT_CHARSET       #指定服务器默认字符集，默认latin1

DDEFAULT_COLLATION     #指定服务器默认的校对规则，默认latin1_general_ci

#5.编译安装

[root@ctos3 mysql-5.7.]# make -j  && make install

#-j参数作用：编译时会占用大量的系统资源，可以通过-j参数指定多个编译命令进行并行编译来提高速度,使用以下命令查看系统CPU核数

[root@ctos3 ~]# cat /proc/cpuinfo | grep processor |wc -l

#6.创建数据目录和修改权限

[root@ctos3 mysql-5.7.]# mkdir /application/mysql/data  #存放数据目录

[root@ctos3 mysql-5.7.29]# mkdir /application/mysql/tmp #存放sock目录

[root@ctos3 mysql-5.7.]# chown -R mysql.mysql /application/mysql/

#7.配置/etc/my.cnf文件

#注意：5.7版本没有模板文件/application/mysql/support-files/my-default.cnf，可根据需要自行添加

[root@ctos3 ~]# cat /etc/my.cnf

[mysqld]

port =

socket = /application/mysql/tmp/mysql.sock

user = mysql

basedir = /application/mysql

datadir = /application/mysql/data

pid-file = /application/mysql/data/mysql.pid

sql_mode='ONLY_FULL_GROUP_BY'

log_error = /application/mysql/mysql-error.log

!includedir /etc/my.cnf.d

[client]

port =

socket = /application/mysql/tmp/mysql.sock

#8.初始化数据库

[root@ctos3 support-files]# /application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

#9.生成服务启动脚本

#设置环境变量

[root@ctos3 support-files]# echo 'export PATH=/application/mysql/bin:$PATH' >> /etc/profile

[root@ctos3 support-files]# source /etc/profile

[root@ctos3 support-files]# tail - /etc/profile

export PATH=/application/mysql/bin:$PATH

#生成启动脚本

[root@ctos3 ~]# cd /application/mysql/support-files/

[root@ctos3 support-files]# ls

magic  mysqld_multi.server  mysql-log-rotate  mysql.server

[root@ctos3 support-files]# cp mysql.server /etc/init.d/mysqld

#启动服务和设置开机自启

[root@ctos3 support-files]# /etc/init.d/mysqld start

Starting MySQL. SUCCESS! 
[root@ctos3 support-files]# chkconfig --add mysqld

[root@ctos3 support-files]# chkconfig mysqld on

#10.登录MySQL(没有密码登录)

[root@ctos3 ~]# mysql -uroot -p

Enter password:

#11.查看版本

mysql> select version();

+-----------+

| version() |

+-----------+
