本博客為源碼安裝mysql5.7.23案例全過程
環境ubuntu18.04
安裝規划：
配置文件：/etc/my.cnf
數據目錄:/r2/mysqldata
安裝目錄：/usr/local/mysql
1.下載mysql-boost
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.23.tar.gz
2.安裝工具
sudo apt-get install cmake -y
apt-get install gcc g++ -y
apt-get install git -y
apt-get install libncurses5 libncurses5-dev -y
sudo apt-get install -y build-essential
sudo apt-get install flex bison -y
sudo apt-get install mpi-default-dev libicu-dev python-dev libbz2-dev -y
3.下載並安裝boost
3.1下載boost部署包
sudo wget https://nchc.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
3.2解壓
tar -zxvf boost_1_59_0.tar.gz
3.3編譯
cd /r2/soft/boost_1_59_0 && ./bootstrap.sh
3.4b2
cd /r2/soft/boost_1_59_0 && ./b2 -a -sHAVE_ICU=1 # the parameter means that it support icu or unicode #執行時間稍微長
3.5安裝
cd /r2/soft/boost_1_59_0 && sudo ./b2 install
這時就把包給裝到/usr/local/include/boost目錄下了
4.創建目錄
cd /r2 && mkdir mysqldata
cd /usr/local && mkdir mysql
5.預編譯msyql
cd /r2/soft/mysql-5.7.23 && sudo cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/r2/mysqldata \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/r2/mysqldata/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLE_DOWNLOADS=1
注意：如果出現錯誤，再次編譯的時候需要刪除CMakeCache.txt文件
6.編譯並安裝
6.1編譯
cd /r2/soft/mysql-5.7.23 && make -j4
6.2安裝
cd /r2/soft/mysql-5.7.23 && make install
7.新建mysql組和用戶並授權
groupadd mysql
useradd -g mysql mysql
mkdir /usr/local/mysql/data
chown -R mysql /usr/local/mysql
chgrp -R mysql /usr/local/mysql
chown -R mysql /r2/mysqldata
chgrp -R mysql /r2/mysqldata
8.添加mysql的環境變量
vim /etc/profile
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
export PATH
讓其生效source /etc/profile
9.初始化
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/r2/mysqldata
這里可以看到初始化密碼2018-10-04T09:36:02.519395Z 1 [Note] A temporary password is generated for root@localhost: p&Lta1fdsD,j
這個就是初始化密碼：p&Lta1fdsD,j
10.優化便捷化操作
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
update-rc.d mysqld defaults
11.啟動mysql
service mysqld start
12.登陸並創建賬號
mysql -uroot -p 之后輸入密碼p&Lta1fdsD,j
set password=password("test123456");
grant insert,update,select,create,index,trigger,alter on *.* to maef@'%' identified by 'test123456';
grant insert,update,select,create,index,trigger,alter on *.* to maef@'localhost' identified by 'test123456';
flush privileges;
13.安裝客戶端
apt install mysql-client-core-5.7 -y
apt install mariadb-client-core-10.1 -y
注意：這時默認的配置什么都沒有，位置/etc/mysql/my.cnf
14.編寫腳本
啟動腳本
啟動腳本start.sh
start.sh腳本內容：
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql --datadir=/r2/mysqldata &```
停止腳本：
```#!/bin/bash
/usr/local/mysql/bin/mysqladmin -uroot -p shutdown &```
#15.優化配置
執行停掉數據庫之后vim /etc/my.cnf之后執行啟動./start.sh即可正常使用
#16.my.cnf附錄如下：
本配置文件主要適用於MySQL 5.7.23版本
