First, MySQL is a relational database, what is the relational relational database, we also talked about the advantages and disadvantages, in a blog: https://blog.51cto.com/14573101/2447264
Now let's talk about, MySQL installation, which has several:
1.RPM | yum install fast speed, easy to install, can not be customized
2. Binary: no need to install, extract that is used, can not be customized
3. Compile Installation: Slow can be customized
prior to 5.5: ./configure make make install
after 5.5: CMake gmake
4. compile and then an RPM, library production yum, yum then install
simple and fast, can be customized, slightly more complex, long production time
Here we choose 3. Compile install, ready to install the first package, here we are using MySQL5.6.36
click on the official download mysql-5.6.36.tar.gz
Baidu cloud disk to download the official website MySQL5.6.36: extraction code: r46x
1 installation and dependencies CMake: yum install -y ncurses-devel libaio-devel cmake
2. Create mysql user useradd -s /sbin/nologin -M mysql
to check the user: id mysql
3. Place the downloaded installation package uploaded to the system software storage directory
4. decompressed tar xf mysql-5.6.36
5. after entering extract the directory cd mysql-5.6.36
6. start the installation;
cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.6.36 \
-DMYSQL_DATADIR=/application/mysql-5.6.36/data \
-DMYSQL_UNIX_ADDR=/application/mysql-5.6.36/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_ZLIB=bundled \
-DWITH_SSL=bundled \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLE_DOWNLOADS=1 \
-DWITH_DEBUG=0
make && make installThese are our own metadata definitions, can be common
so far compiled start optimizing the configuration
7. soft connection to make mysql directory (the role of making soft connections: easy to upgrade, optimization commands, etc.) ln -s /application/mysql-5.6.36/ /application/mysql
8. copy of the configuration file
\cp support-files/my*.cnf /etc/my.cnf9. initialize the database /application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data --user=mysql
10. Create tmp directory (as above, we define the sock file here) mkdir -p /application/mysql/tmp
11. mysql folder to set permissions to prevent insufficient privileges and other issues chown -R mysql.mysql /application/mysql/
12. Set the startup script \cp -a support-files/mysql.server /etc/init.d/mysqld
13. mysql can start up!
/etc/init.d/mysqld start
checking whether the start
netstat -lntup|grep 3306
ps -ef|grep mysql
lsof -i:330614. The configuration environment variable
echo 'PATH=/application/mysql/bin/:$PATH' >>/etc/profile
tail -1 /etc/profile
source /etc/profile在命令行输入mysql即可进入，默认空密码
