Mysql编译

Mysql编译

1、编译环境

硬件环境：香橙派5 aarch64架构
软件环境：Ubuntu 22.04.3 LTS
编译版本：mysql-5.7.43.tar.gz
编译目录：/data/make_test/mysql_for_make/mysql-5.7.43 #根据需要调整，本次测试使用

2、编译操作

（1）、获取源码包

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.43.tar.gz
tar -zxf mysql-5.7.43.tar.gz 

（2）、添加mysql用户

#创建用户，-M表示不创建家目录,/bin/nologin禁止用户登录
useradd -r mysql -M -s /bin/nologin
cat /etc/passwd | grep mysql
mysql:x:1001:1001::/home/mysql:/bin/nologin

（3）、安装编译工具

apt update
apt install build-essential cmake bison libncurses5-dev libssl-dev libtirpc-dev libaio-dev libedit-dev libxml2-dev libboost-dev liblz4-dev libzstd-dev

（4）、编译配置

#注：目录、端口配置根据需求自行调整，以下目录仅用于演示
cmake . \
-DDOWNLOAD_BOOST=1 \															#自动下周boost库,下载较慢
-DWITH_BOOST=boost/boost_1_59_0/ \ 												#指定 Boost 库路径
-DCMAKE_INSTALL_PREFIX=/usr/local/src/mysql-5.7.43/ \   						#MySQL 安装目录
-DSYSCONFDIR=/etc \																#配置文件目录（默认 my.cnf 存放位置）
-DMYSQL_DATADIR=/usr/local/src/mysql-5.7.43/data \								#数据库数据文件存放目录
-DMYSQL_TCP_PORT=3305 \															#MySQL 默认端口
-DDEFAULT_CHARSET=utf8 \														#设置默认字符集
-DDEFAULT_COLLATION=utf8_general_ci \											#设置默认排序规则
-DWITH_SSL=system \																#使用系统自带的 OpenSSL
-DWITH_INNOBASE_STORAGE_ENGINE=1												#启用 InnoDB 存储引擎

#boost自动下载网速较慢，建议手动下载解压,
wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
mkdir -p /data/make_test/mysql_for_make/mysql-5.7.43/boost/
tar -zxvf boost_1_59_0.tar.gz -C /data/make_test/mysql_for_make/mysql-5.7.43/boost/

（5）编译安装

#编译
make

#多线程编译
make -j 线程数

#安装
make install

#修改目录权限
chown mysql:mysql -R /usr/local/src/mysql-5.7.43/

（6）、配置my.cnf文件

vi /etc/my.cnf 
#内容如下
[client]
port = 3306
default-character-set=utf8
socket = /usr/local/src/mysql-5.7.43/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/src/mysql-5.7.43/mysql.sock

[mysqld]
user = mysql
basedir = /usr/local/src/mysql-5.7.43
datadir = /usr/local/src/mysql-5.7.43/data
port = 9080
character_set_server=utf8
# 0：区分大小写，1：不区分大小写
#lower_case_table_names=1
pid-file = /usr/local/src/mysql-5.7.43/mysqld.pid
socket = /usr/local/src/mysql-5.7.43/mysql.sock
server-id = 1

（7）、初始化

./bin/mysqld --initialize --console --user=mysql --basedir=/usr/local/src/mysql-5.7.43 --datadir=/usr/local/src/mysql-5.7.43/data

（7）、登录验证

#启动
cd /usr/local/src/mysql-5.7.43/support-files
./mysql.server start 

#连接
mysql -u root -p -P9080

#修改root密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
FLUSH PRIVILEGES;

#允许任意主机使用密码登录root，you_root_passwd替换为自己root密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'you_root_passwd' WITH GRANT OPTION;
