-- 1. Create a group and user for mysql

# useradd -M -s /sbin/nologin mysql

-- 2. Install the required library and Compiler

# yum install ncurses-devel openssl-devel cmake -y

-- 3. Extract

# tar zxvf mysql-5.6.35.tar.gz# cd mysql-5.6.35

-- 4. Compile and install

# cmake \-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DMYSQL_DATADIR=/usr/local/mysql/data \-DSYSCONFDIR=/etc \-DWITH_MYISAM_STORAGE_ENGINE=1 \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_MEMORY_STORAGE_ENGINE=1 \-DWITH_READLINE=1 \-DMYSQL_TCP_PORT=3306 \-DENABLED_LOCAL_INFILE=1 \-DWITH_PARTITION_STORAGE_ENGINE=1 \-DEXTRA_CHARSETS=all \-DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_general_ci \-DMYSQL_USER=mysql \-DWITH_DEBUG=0 \-DWITH_SSL=system# make# make install

CentOS 6.5 minimal compilation and installation mysql 5.5.35 multi-instance Configuration

1. Disable the Firewall

1234567 [root@mysql ~]# service iptables stopiptables: Setting chains to policy ACCEPT: filter   [ OK ]iptables: Flushing firewall rules:       [ OK ]iptables: Unloading modules:        [ OK ][root@mysql ~]# chkconfig iptables off[root@mysql ~]# chkconfig iptables --listiptables  0:off 1:off 2:off 3:off 4:off 5:off 6:off

2. Disable selinux

12 [root@mysql ~]# setenforce 0[root@mysql ~]# vim /etc/sysconfig/selinux

Modify the following line;

SELINUX=disabled12 [root@mysql ~]# getenforce Permissive

3. Install mysql dependency packages and compilation tools;

1234 [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. Preparations before installation;

4.1 installation path:

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

4.2 database path:

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

4.3 create users and user groups

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

4.4 grant the directory storage permission

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

5. Compile and install mysql 5.5.35

1234567 [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 multi-instance database file storage location;

12345678 [root@mysql ~]# mkdir -p /data/{3306,3307}/data[root@mysql ~]# tree /data/data|-- 3306|  `-- data`-- 3307  `-- data4 directories, 0 files 

7. modify the configuration file (my. cnf) into the 3306 and 3307 directories respectively;

123456789 [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 must be specified during database initialization.

123 [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. the startup script can be added to the boot auto-start file.

12 [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 &

9.1 view the port;

12345678 [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 0.0.0.0:3307        0.0.0.0:*          LISTEN   11621/mysqld    tcp    0   0 0.0.0.0:22         0.0.0.0:*          LISTEN   1266/sshd      tcp    0   0 0.0.0.0:3306        0.0.0.0:*          LISTEN   11338/mysqld    tcp    0   0 :::22            :::*            LISTEN   1266/sshd      udp    0   0 0.0.0.0:68         0.0.0.0:*                969/dhclient

10. log on to a multi-instance Database

12 [root@mysql mysql]# /usr/local/mysql/bin/mysql -u root -p -P 3306 -S /data/3306/mysql.sock[root@mysql mysql]# /usr/local/mysql/bin/mysql -u root -p -P 3307 -S /data/3307/mysql.sock

11. Disable mysql multi-instance mode

12 [root@mysql mysql]# /usr/local/mysql/bin/mysqladmin -u root -p -P 3306 -S /data/3306/mysql.sock shutdown  [root@mysql mysql]# /usr/local/mysql/bin/mysqladmin -u root -p -P 3307 -S /data/3307/mysql.sock shutdowncat ​/etc/my.cnf [mysqld1]datadir=/data/mysqlsocket=/tmp/mysql.sockuser=mysqlsymbolic-links=0skip-name-resolveserver-id=1221max_connections = 2000binlog-ignore-db=mysqlbinlog-ignore-db=testbinlog-ignore-db=information_schemabinlog-ignore-db=performance_schemainnodb_buffer_pool_size = 2Ginnodb_additional_mem_pool=16Minnodb_log_file_size=256Minnodb_flush_log_at_trx_commit=2character_set_server=utf8collation_server = utf8_general_cireplicate_ignore_db = mysqlslave-skip-errors=allrelay_log=/data/mysql/[mysqld2]port=3307server-id=1222log-error=/tmp/mysqld2.logdatadir=/data/mysql_livesocket=/tmp/mysql2.sockuser=mysqlsymbolic-links=0skip-name-resolvecharacter_set_server=utf8collation_server = utf8_general_cimax-connections=500default-storage-engine=INNODBinnodb_file_per_tablelog-bin=mysql-binrelay-log-info-repository=TABLEmaster-info-repository=TABLEexpire_logs_days=10binlog_format=ROWtransaction-isolation=READ-COMMITTEDbinlog-ignore-db=mysqlbinlog-ignore-db=testbinlog-ignore-db=information_schemabinlog-ignore-db=performance_schemaslow_query_log=TRUEslow_query_log_file=/tmp/mysqld_slow_query2.loglong_query_time=3replicate_ignore_db = mysqlslave-skip-errors=all[mysqld3]server-id=1223port=3308log-error=/tmp/mysqld3.logdatadir=/data/mysqlsocket=/tmp/mysql3.sockuser=mysqlsymbolic-links=0skip-name-resolvecharacter_set_server=utf8collation_server = utf8_general_cimax-connections=500default-storage-engine=INNODBinnodb_file_per_table​log-bin=mysql-binrelay-log-info-repository=TABLEmaster-info-repository=TABLEexpire_logs_days=10binlog_format=ROWtransaction-isolation=READ-COMMITTEDbinlog-ignore-db=mysqlbinlog-ignore-db=testbinlog-ignore-db=information_schemabinlog-ignore-db=performance_schemaslow_query_log=TRUEslow_query_log_file=/tmp/mysqld_slow_query3.loglong_query_time=3replicate_ignore_db = mysqlslave-skip-errors=all[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/data/mysql/mysqld.pid
