前期准备：

yum install gcc gcc-c++ make cmake ncurses-devel bison perl #依赖包

建用户：

groupadd mysql

useradd mysql -s /sbin/nologin -M -g mysql

建立安装目录：

mkdir /data/mysql3306 -pv

chown -R mysql. /data/mysql3306/

下载&解压：

wget –c http://download.softagency.net/MySQL/Downloads/MySQL-5.5/mysql-5.5.44.tar.gz

tar xf mysql-5.5.44.tar.gz

cd mysql-5.5.44

编译安装：

cmake \

-DCMAKE_INSTALL_PREFIX=/data/app/mysql3306 \

-DMYSQL_DATADIR=/data/mysql3306 \

-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 \

-DWITH_DEBUG=0 \

-DMYSQL_USER=mysql \

-DMYSQL_UNIX_ADDR=/data/mysql3306/mysql3306.sock

make && make install ;echo $?           #echo 输出执行结果，0表示成功

配置：

cp -arp /tmp/mysql-5.5.44/support-files/my-large.cnf /data/mysql3306/my.cnf

chown -R mysql. /data/mysql3306/my.cnf

vim /data/mysql3306/my.cnf

添加以下黄底部分参数

[mysqld]

port            = 3306

datadir = /data/mysql3306 #数据目录

basedir = /data/app/mysql3306 #程序目录

socket          = /data/mysql3306/mysql3306.sock

key_buffer_size = 256M

max_allowed_packet = 1M

table_open_cache = 256

sort_buffer_size = 1M

read_buffer_size = 1M

read_rnd_buffer_size = 4M

myisam_sort_buffer_size = 64M

thread_cache_size = 8

query_cache_size= 16M

# Try number of CPU‘s*2 for thread_concurrency

thread_concurrency = 8

log-bin=mysql-bin  #二进制日志，主从复制用

binlog_format=mixed #混合模式复制(mixed-based replication,

server-id = 1 #多服务器时，区分mysql服务器身份的ID

初始化mysql:

cd /data/app/mysql3306/

./scripts/mysql_install_db --basedir=/data/app/mysql3306/ --datadir=/data/mysql3306/ --user=mysql

添加为系统服务：

cp /tmp/mysql-5.5.44/support-files/my-medium.cnf /etc/my.cnf

cp /tmp/mysql-5.5.44/support-files/mysql.server /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

chkconfig --level 35 mysqld on

chkconfig --list |grep mysql  #验证

启动

/etc/init.d/mysqld restart

ERROR! MySQL server PID file could not be found! #再次restart 没有再报错

设置密码为123456

/data/app/mysql3306/bin/mysqladmin -uroot password ‘123456‘

登陆

mysql -uroot -p123456
