Source installation!!!
After three nights of trials + for Baidu and CSDN, I finally concluded that I encountered various errors during the period and created 3 virtual machines. Finally, I concluded that there was no problem after two tests.
Second, I found that I wrote before Not easy to understand
0. First of all preparations, source code package
mysql-boost-5.7.14.tar.gz
Download link https://downloads.mysql.com/archives/community/ and find the version you want
1. First create a directory
mkdir /soft
to store the package, and transfer the package to the soft root in Linux .
Using xfpttransfer, you can also directly shortcut keys in xshellctrl+alt+f
Drag the mysql-boost-5.7.14.tar.gz file into the virtual machine /soft/directory, and then enter the /softdirectory
2. Install development tools and development kits
yum install -y cmake gcc-c++* make ncurses-devel
yum install libaio libaio-devel openssl-devel -y
yum install perl-Data-Dumper -y
yum install net-tools vim -y
After the installation is complete, and no error is reported, proceed to the next step
3. After decompressing the file
, the directory where you are at this time must be the directory where the source file /softis located, that is, the directory where the file was just stored/soft
cd /soft/
tar xf mysql-boost-5.7.14.tar.gz -C /usr/local/src/
4. To mysqlcreate users and groups
groupadd -r -g 306 mysql
useradd -g 306 -r -u 306 mysql
5. cmake compile source code to install MySQL database
! ! ! ! ! ! !
Be sure to enter the directory where the file is decompressed first,
cd /usr/local/src/mysql-5.7.14/
and then execute the following codes in sequence
下面代码很长，不要少复制了
========
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DMYSQL-USER=mysql \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=./boost
=========================================================================================
等待上面执行完
=========================================================================================
make -j 4 && make install
The length of the code must not be less copied
\
This waiting time is quite long, if it gets stuck, please turn off the virtual machine, and then set the configuration to 4G+4 cores (better than this)
and restart
===!!!重新执行就行了！！！但是一定要记得切换目录，要不然会报错===
cd /usr/local/src/mysql-5.7.14/
make -j 4 && make install
The installation is complete and no error is reported, proceed to the next step
6. Change the folder owner and group
chown -R mysql.mysql /usr/local/mysql/
7. Initialize mysql, a random password will be given at the end of initialization
Initialization code
=========
/usr/local/mysql/bin/mysqld --initialize \
--user=mysql --datadir=/usr/local/mysql/data \
--basedir=/usr/local/mysql/
=========
The random password looks like the following, in the last line
root@localhost: FhvqcGRy9W#8
8. Provide the main configuration file for mysql
cd /usr/local/mysql/
\cp support-files/my-default.cnf /etc/my.cnf
================================
vim /etc/my.cnf
添加如下行指定mysql数据文件的存放位置
[mysqld]
datadir = /usr/local/mysql/data
Just change it to the picture like this
9. Provide sysv service script for mysql
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld --添加为系统服务
chkconfig mysqld on --添加为系统服务
10. Modify the PATH environment variable so that the system can directly use mysql related commands
vim /etc/profile.d/mysql.sh
=========将下面这段内容写入保存
export PATH=$PATH:/usr/local/mysql/bin
=========
！！！！！！！！！一定要做下面这步
source /etc/profile.d/mysql.sh 这个是为了现在应用环境
Start MySQL
systemctl start mysqld
=========================================================================================
查看MySQL运行状态
systemctl status mysqld.service --如果为active则表示MySQL已经运行了
或者
systemctl is-active mysql.service --显示为active也是启动了
So far, all installation is complete
11. If you don’t remember the random password, you can check it with the following method. If you can’t check it, there is a high probability that the initialization was not successful. It is recommended to reinstall it.
默认有个随机密码：
more /var/log/mysql.log
也可以使用grep命令查询密码：
grep 'temporary password' /var/log/mysqld.log
