一、安装依赖包

yum install ncurses-devel libaio-devel -y

二、下载cmake2.8.8和mysql.5.5.32

PS:我这里直接下载好了所以就用rz上传了

三、解压cmake-2.8.8.tar.gz

tar xf cmake-2.8.8..tar.gz

四、编译cmake

cd cmake-2.8.8

./configure

gmake && gmake install

五、解压mysql-5.5.32

tar xf mysql-5.5.32.tar.gz

六、创建mysql用户

useradd -s /sbin/nologin -M mysql

七、进入mysql-5.5.32目录并编译

cd /home/ljx/tools/mysql-5.5.32

cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \

-DMYSQL_DATADIR=/application/mysql-5.5.32/data \

-DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/tmp/mysql.sock \

-DEXTRA_CHARSETS=gbk.gb2312.utf8.ascii \

-DENABLED_LOCAL_INFILE=ON \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \

-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \

-DWITH_FAST_MUTEXES=1 \

-DWITH_ZLIB=bundled \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_READLINE=1 \

-DWITH_EMBEDDED_SERVER=1 \

-DWITH_DEBUG=0

make && make install

八、复制my.cnf

cp /home/ljx/tools/mysql-5.5.32/support-files/my-small.cnf /etc/my.cnf

九、设置软链接

ln -s /application/mysql-5.5.32/ /application/mysql

十、配置环境变量并让其生效

echo ‘export PATH=/application/mysql/bin:$PATH‘>>/etc/profile

source /etc/profile

十一、授权

chown -R mysql.mysql /application/mysql/data/

chmod -R 1777 /tmp/

十二、创建mysql多实例的数据文件目录、

mkdir -p /data/{3306,3307}/data

十三、创建3306和3307的my.cnf文件

vi /data/3306/my.cnf

#############3306##############

#3307的话这里就不写了就是把3306替换成3307,server-id = 1换成server-id = 3就行了；

[client]

port            =3306

socket          =/data/3306/mysql.sock

[mysql]

no-auto-rehash

[mysqld]

user    = mysql

port    = 3306

socket  = /data/3306/mysql.sock

basedir = /application/mysql

datadir = /data/3306/data

open_files_limit                =1024

back_log = 600

max_connections = 800

max_connect_errors = 3000

table_cache = 614

max_allowed_packet =8M

sort_buffer_size = 1M

join_buffer_size = 1M

thread_cache_size = 100M

thread_concurrency = 2

query_cache_size = 2M

query_cache_limit = 1M

query_cache_min_res_unit = 2k

thread_stack = 192K

transaction_isolation = READ-COMMITTED

tmp_table_size = 2M

max_heap_table_size = 2M

long_query_time =1

log-error = /data/3306/error.log

log-slow-queries = /data/3306/slow.log

pid-file = /data/3306/mysql.pid

#log-bin = /data/3306/mysql.bin

relay-log = /data/3306/relay-bin

relay-log-info-file = /data/3306/relay-log.info

binlog_cache_size = 1M

max_binlog_cache_size = 1M

max_binlog_size = 2M

expire_logs_days = 7

key_buffer_size = 16M

read_buffer_size = 1M

bulk_insert_buffer_size = 1M

myisam_sort_buffer_size = 1M

myisam_max_sort_file_size = 10G

myisam_repair_threads = 1

myisam_recover

skip-name-resolve

slave-skip-errors = 1032,1062

replicate-ignore-db=mysql

server-id = 1

innodb_additional_mem_pool_size = 4M

innodb_buffer_pool_size = 32M

innodb_data_file_path = ibdatal:128M:autoextend

innodb_file_io_threads = 4

innodb_thread_concurrency = 8

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 2M

innodb_log_file_size = 4M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 90

innodb_lock_wait_timeout = 120

innodb_file_per_table = 0

[mysqldump]

quick

max_allowed_packet = 2M

[mysqld_safe]

log-error=/data/3306/mysql_oldboy3306.err

pid-file=/data/3306/mysqld.pid

十四、授权data目录

chown -R mysql.mysql /data/

十五、初始化

Cd /application/mysql/scripts/

./mysql_install_db--basedir=/application/mysql --datadir=/data/3306/data --user=mysql

./mysql_install_db--basedir=/application/mysql --datadir=/data/3307/data --user=mysql

十六、启动实例3306、3307

mysqld_safe --defaults-file=/data/3306/my.cnf 2>&1 > /dev/null &

mysqld_safe --defaults-file=/data/3307/my.cnf 2>&1 > /dev/null &

十七、检查3306和3307端口是否启动

netstat -lntup|grep 330

十八、为两个实例增加帐号密码

mysqladmin -u root -S /data/3306/mysql.sock password ‘ljx1‘

mysqladmin -u root -S /data/3307/mysql.sock password ‘ljx2‘

十九、登陆实例

mysql -uroot -pljx1 -S /data/3306/mysql.sock

mysql -uroot -pljx1 -S /data/3306/mysql.sock

mysql-5.5.32多实例配置
