3. Install mysql dependency packages and compilation tools

[root@mysql ~] # yum install libaio-devel-y [root@mysql ~] # yum install-y ncurses-devel [root@mysql] # yum install-y gcc gcc-c++ [root@mysql ~] # yum install-y cmake

4. Prepare before installation

4.1. Installation path:

[root@mysql ~] # mkdir / usr/local/mysql

4.2. Database path:

[root@mysql ~] # mkdir / data/mysql-p

4.3. Create users and user groups

[root@mysql ~] # groupadd mysql [root@mysql ~] # useradd-r-g mysql-s / bin/false mysql

4.4. Give permission to the data storage directory

[root@mysql] # chown mysql:mysql-R / data/mysql

5. Compile and install mysql 5.5.35

[root@mysql] # yum install-y lrzszroot@mysql ~] # mkdir / package [root@mysql ~] # cd / package/ [root@mysql package] # tar xf mysql-5.5.32.tar.gz [root@mysql package] # cd mysql-5.5.32 [root@mysql mysql-5.5.32] # cmake. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock-DDEFAULT_CHARSET=utf8-DDEFAULT_COLLATION=utf8_general_ci-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk-DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_READLINE=1-DENABLED_LOCAL_INFILE=1-DMYSQL_DATADIR=/data/mysql/-DMYSQL_USER=mysql-DMYSQL_TCP_PORT= 3306 [root @ mysql mysql-5.5.32] # make & & make install

6. Create a location for storing multi-instance database files

[root@mysql ~] # mkdir-p / data/ {3306 data/ 3307} / data [root@mysql ~] # tree / data/data |-- 3306 | `--data`-- 3307`-- data4 directories, 0 files

7. Modify the configuration file (my.cnf), such as the following line, and put it in the 3306 and 3307 directories respectively.

[root@mysql 3306] # vim my.cnf [client] port = 3306socket = / data/3306/ mysql.sock [mysqld] port = 3306socket = / data/3306/mysql.sockdatadir = / data/3306server-id = 3306

8. Initialize the database

Note: different data directories need to be specified when initializing the database

[root@mysql mysql-5.5.32] # cd / usr/local/mysql/ [root@mysql mysql] # scripts/mysql_install_db-user=mysql-basedir=/usr/local/mysql-datadir=/data/3306 [root@mysql mysql] # scripts/mysql_install_db-user=mysql-basedir=/usr/local/mysql-datadir=/data/3307

9. Start multiple instances, and the startup script can be added to the boot file.

[root@mysql mysql] # / usr/local/mysql/bin/mysqld_safe-- defaults-file=/data/3306/my.cnf 2 > & 1 > / dev/null & [root@mysql mysql] # / usr/local/mysql/bin/mysqld_safe-- defaults-file=/data/3307/my.cnf 2 > & 1 > / dev/null &

[root@mysql mysql] # netstat-tunlpActive Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0 tunlpActive Internet connections 3307 0.0.0.015 * LISTEN 11621/mysqld tcp 0 0 0.0.0.015 0.0.0.0 * LISTEN 1266/sshd tcp 0 00.0.0.0 3306 0.0.0.0 0 0: 22:: * LISTEN 1266/sshd udp 0 0 0.0.0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 8. 0. 0. 0. 0. 0. 0. 0. 0
