1.安装gcc-c++、ncurses依赖包
# yum install gcc-c++ ncurses-devel
2.安装cmake，用来编译mysql
# tar -xvf cmake-3.2.0-.tar.gz # mv cmake-3.2.0 cmake # mv cmake /tmp/ # cd /tmp/cmake/ # ./bootstrap # make # make install # cmake --version
3.安装bison
# tar -xvf bison-3.0.tar.gz # mv bison-3.0 bison # mv bison /tmp # cd /tmp/bison/ # ./cofigure # make # make install # bison --version
4.创建mysql用户
# /usr/sbin/groupadd mysql # useradd -s /sbin/nologin -g mysql -M mysql
5.编译安装
配置
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql
生成可执行文件
# make
安装
# make install
6.创建多实例的数据文件目录
# mkdir -p /data/{3306,3307}/data/
# mkdir -p /data/{3306,3307}/log/
# tree /data
/data #多实例的根目录
├── 3306 #3306实例的根目录
│ ├── data #3306实例的数据目录
│ └── log #3306实例的日志目录
│ └── tmp #3306实例的临时文件目录
└── 3307 #3307实例的根目录
├── data #3307实例的数据目录
└── log #3307实例的日志目录
└── tmp #3307实例的临时文件目录
data - 存放数据文件：数据，索引，二进制日志（bin log），重放日志（replay log）。
log - 存放日志文件：慢查询日志，错误日志。
tmp - 存放临时文件：进程ID文件。
7.配置多实例的配置文件
为每个实例建立一个配置文件
# vi /data/3306/my.cnf [client] default-character-set = utf8 port = 3306 socket = /data/3306/tmp/mysql.sock [mysqld] server-id = 1 collation-server = utf8_unicode_ci init-connect = 'SET NAMES utf8' character-set-server = utf8 port = 3306 socket = /data/3306/tmp/mysql.sock datadir = /data/3306/data/ log-error = /data/3306/log/mysql.err pid-file = /data/3306/tmp/mysql.pid log-bin = /data/3306/data/mysql-bin relay_log = /data/3306/data/relay-bin slow_query_log_file = /data/3306/log/slowquery.log general_log_file = /data/3306/log/general.log skip-external-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M binlog_format = mixed slow_query_log = 1 long_query_time = 1 general_log = off [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
# vi /data/3307/my.cnf [client] default-character-set = utf8 port = 3307 socket = /data/3307/tmp/mysql.sock [mysqld] server-id = 2 collation-server = utf8_unicode_ci init-connect = 'SET NAMES utf8' character-set-server = utf8 port = 3307 socket = /data/3307/tmp/mysql.sock datadir = /data/3307/data/ log-error = /data/3307/log/mysql.err pid-file = /data/3307/tmp/mysql.pid log-bin = /data/3307/data/mysql-bin relay_log = /data/3307/data/relay-bin slow_query_log_file = /data/3307/log/slowquery.log general_log_file = /data/3307/log/general.log skip-external-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M binlog_format = mixed slow_query_log = 1 long_query_time = 1 general_log = off [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
8.配置mysql命令的环境变量
方法一：
# echo 'export PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile
# source /etc/profile
方法二：
把/usr/local/mysql/bin/下面的命令拷贝到全局系统命令路径/usr/local/sbin/下，或者做个link
9.初始化数据库,创建基础的数据库文件
# cd /usr/local/mysql/scripts/ #./mysql_install_db --defaults-file=/data/3306/my.cnf --user=mysql --basedir=/usr/local/mysql #./mysql_install_db --defaults-file=/data/3307/my.cnf --user=mysql --basedir=/usr/local/mysql
10.配置多实例的文件权限
授权mysql用户和组管理多实例目录/data
# chown -R mysql.mysql /data
11.启动
# mysqld_safe --defaults-file=/data/3306/my.cnf 2>&1 > /dev/null & # mysqld_safe --defaults-file=/data/3307/my.cnf 2>&1 > /dev/null &
12.修改的root用户的密码并且限制只能本机登陆
# mysqladmin -S /data/3306/tmp/mysql.sock -u root -h 'localhost' password 'xxxx' # mysqladmin -S /data/3307/tmp/mysql.sock -u root -h 'localhost' password 'xxxx'
13.使用root用户登陆
# mysql -S /data/3306/tmp/mysql.sock -u root -p # mysql -S /data/3307/tmp/mysql.sock -u root -p
14.停止实例
# mysqladmin -S /data/3306/tmp/mysql.sock -u root -p shutdown # mysqladmin -S /data/3307/tmp/mysql.sock -u root -p shutdown
