1. First install the dependency package
yum install -y gcc gcc-c++ ncurses-devel perl openssl-devel
The most important thing is, don’t forget to install openssl-devel
(free learning video tutorial recommended : mysql video tutorial)
2. Install cmake
tar -xzvf cmake-3.8.1.tar.gz cd cmake-3.8.1 ./bootstrap make && make install
3. Install MySQL5.7.18
First download the installation package. My installation version is ：mysql-boost-5.7.18.tar.gz
You need to download boost. I am matching the boost_1_59_0 version
Download, decompress it in the /usr/local directory, and rename it to boost
First add the system account corresponding to MySQL to ensure its local file permission allocation:
groupadd mysql useradd -r -g mysql mysql
Create the database directory:
mkdir -p /var/mysql/data chown mysql:mysql /var/mysql/data
Enter the decompressed MySQL installation package:
cd mysql-boost-5.7.18 cmake . \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ \ -DINSTALL_DATADIR=/usr/local/mysql/data/master \ -DSYSCONFDIR=/usr/local/mysql/etc \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DEXTRA_CHARSETS=all \ -DWITH_SSL=system \ -DWITH_EMBEDDED_SERVER=1 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_ARCHIVE_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_FEDERATED_STORAGE_ENGINE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \ -DMYSQL_USER=mysql \ -DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysql.sock \ -DDOWNLOAD_BOOST=1 \ -DWITH_BOOST=/usr/local/boost
If an error occurs, after modification, you need to delete the CMakeCache.txt file in the current directory, and then restart cmake
make && make install
After completing the above steps, you need to change the owner of the mysql installation directory. For example, the directory we installed is /usr/local/mysql. Use the command
chown -R mysql:mysql /usr/local/mysql
to modify the directory owner. At this time, copy a copy of the default configuration file
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
After the blogger has completed the installation, there is no my-default.cnf file. You need to create it yourself. Attach the content of the file:
#For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.

If the prompt already exists If the file is overwritten, just overwrite it.
Then perform the initialization operation of the database.
/usr/local/mysql/bin/mysqld --initialize --user=mysql，
At this time, the database will be initialized and a database root account will be created. However, please note that this account has a default password. During initialization, the screen will Output the initialized password. If you missed it, you can see the default password by looking at /root/.mysql_secret.
Execute cp /usr/local/mysql/support-files/mysql.server /etc/init.d, copy the mysql service startup script, and then execute service mysql.server start to start mysql.
Finally /usr/local/mysql/bin/mysql -rroot -p, enter the password and press Enter. If Access denied for user 'root'@'localhost' (using password: YES) appears, under normal circumstances
service mysql.server restart Restart
After passing, you can use the following command to reset the root password
set password=password('你的密码');
At this point, the basic installation process is completed
The following method can be used to set up the startup
Commandecho "service mysqld start" >> /etc/rc.local
Or enter the /etc/ directory, Directly edit the rc.local file with vim rc.local, add "service mysqld start" in the last line, save and exit.
