源码编译安装mysql5.7.30

1、环境准备

[root@localhost conf]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core) 
[root@localhost conf]# uname -r
3.10.0-957.el7.x86_64
[root@localhost conf]# 

2、先卸载本机版本安装过的mysql软件

#查看是否安装过mysql和mariadb
  rpm -qa | grep mysql
  rpm -qa | grep mariadb
#卸载历史版本
rpm -e --nodeps mariadb-libs

3. 下载mysql包

https://downloads.mysql.com/archives/community/

wget -c https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.30.tar.gz
wget -c https://cdn.mysql.com/archives/mysql-5.7/mysql-boost-5.7.30.tar.gz

4.安装mysql-boost

MySQL从5.7版本之后，boost是必须的，这里需要解压到相应的安装目录，后面Cmake会用到

mkdir -p /usr/local/mysql-boost
tar xvf mysql-boost-5.7.30.tar.gz -C /usr/local/mysql-boost

5、安装依赖包

yum install -y cmake make gcc gcc-c++ bison ncurses ncurses-devel libaio autoconf

6、添加mysql用户和用户组

 groupadd mysql
 useradd -M -s /sbin/nologin -r -g mysql mysql
 #注释 -M 不创建家目录 -s 指定默认登录shell -r创建系统账户 -g指定用户登录组的GID或组名

7、解压及规划安装目录

解压下载的源文件

tar xvf mysql-5.7.30.tar.gz
cd mysql-5.7.30

规划安装目录

#安装目录
mkdir -p /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql

#数据目录
mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql

8、开始编译mysql

进入解压后的源文件目录

cd mysql-5.7.30

cmake:

cmake -DMYSQL_USER=mysql \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql/ \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
 -DWITH_MEMORY_STORAGE_ENGINE=1 \
 -DWITH_READLINE=1 \
 -DMYSQL_UNIX_ADDR=/data/mysql/mysqld.sock \
 -DMYSQL_TCP_PORT=3306 \
 -DENABLED_LOCAL_INFILE=1 \
 -DDOWNLOAD_BOOST=1 \
 -DWITH_PARTITION_STORAGE_ENGINE=1 \
 -DEXTRA_CHARSETS=all \
 -DDEFAULT_CHARSET=utf8 \
 -DDEFAULT_COLLATION=utf8_general_ci \
 -DWITH_BOOST=/usr/local/mysql-boost/mysql-5.7.30/boost

注：-DWITH_BOOS参数就是第四步骤的解压后路径,注意要写到boost目录
说明：如果编译出错，没有通过，检测参数后重新运行配置，需要删除CMakeCache.txt文件
#make clean
#rm -f CMakeCache.txt

参数从哪里找：
http://www.mysql.com→→Documentation→→选择对应的版本（5.7）Installation & Upgrades→→Installing MySQL from Source →→MySQL Source-Configuration Options
直接点击url: https://dev.mysql.com/doc/refman/5.7/en/source-configuration-options.html

编译安装

make -j 4&&make install

7、编辑mysql配置文件

7.1、my.cnf 默认是没有的，需要手动输入

/etc/my.cnf 
[mysqld]
port=3306
user=mysql
basedir=/usr/local/mysql
datadir=/data/mysql
socket=/data/mysql/mysqld.sock
log-error=/data/mysql/mysql.err
pid-file=/data/mysql/mysql.pid
character-set-server=utf8

7.2添加path路径，让系统能够读到mysql命令

#把mysql的bin路径加入PATH
echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
#让PATH变量修改立即生效 
source /etc/profile   

7.3生成启动脚本并做成服务

#设置服务自动启动
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
#设置服务自动启动
chkconfig mysql on 

7.4创建软链接

由于系统默认会查找/usr/bin下的命令，如果这个命令不在这个目录下，当然会找不到命令，我们需要做的就是映射一个链接到/usr/bin目录下，相当于建立一个链接文件。

ln -s /usr/local/mysql-5.7.30/bin/mysql /usr/bin

8、修改权限并初始化数据库

chown -R mysql:mysql /usr/local/mysql
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

9、启动mysql测试

/etc/init.d/mysql start

10、查看初始密码并修改

#查看临时密码
grep password /data/mysql/mysql.err
#使用临时密码登录后修改密码
SET PASSWORD = PASSWORD('123456');
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
FLUSH PRIVILEGES;  

一键部署脚本

#!/bin/bash
#auto install MYSQL
#by MR.xu 2020-07
#MYSQL define path variable
#auto install mysql

#mysql define path variable
M_FILES=mysql-5.7.30.tar.gz
M_FILES_DIR=mysql-5.7.30
M_URL=https://cdn.mysql.com/archives/mysql-5.7/
M_PREFIX=/usr/local/mysql
BOOST_FILES=mysql-boost-5.7.30.tar.gz
