Detailed explanation of how to install MySQL5.7.18 under centos system

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:

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.
