[MySQL] Linux下MySQL-5.6源码安装
本文主要介绍centos下源码安装MySQL 5.6的方法，centos的版本为5.8.
注：以下操作没有特殊说明，都是以root账户执行。
2）先安装cmake（mysql5.5以后源码安装都得通过cmake编译）
[plain]
# yum install cmake
并确保以下两个包已安装最新版：
ncurses
ncurses-devel
3）添加MySQL用户组和用户
[plain]
# groupadd mysql
# useradd mysql
4）创建MySQL软件安装目录和数据存放目录
[plain]
mkdir -p /opt/mysql #MySQL安装目录
chown -R mysql:mysql /opt/mysql
mkdir -p /data/mysql #MySQL数据存放目录
mkdir -p /data/mysql/data #存放数据
mkdir -p /data/mysql/log #存放日志
mkdir -p /data/mysql/tmp #存放临时文件
chown -R mysql:mysql /data/mysql
5）cmake编译安装MySQL
[plain]
tar zxvf mysql-5.6.13.tar.gz
cd mysql-5.6.13
cmake . -DCMAKE_INSTALL_PREFIX=/opt/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/opt/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1
make
make install
参数说明：
-DCMAKE_INSTALL_PREFIX=/opt/mysql //指定安装目录
-DINSTALL_DATADIR=/data/mysql //指定数据存放目录
-DSYSCONFDIR=/opt/mysql //指定配置文件目录（本例的配置文件为/opt/mysql/my.cnf）
-DDEFAULT_CHARSET=utf8 //指定字符集
-DDEFAULT_COLLATION=utf8_general_ci //指定校验字符
-DEXTRA_CHARSETS=all //安装所有扩展字符集
-DENABLED_LOCAL_INFILE=1 //允许从本地导入数据
上述步骤执行成功后，MySQL软件已成功安装至/opt/mysql目录下。
7）编辑配置文件my.cnf
[plain]
[client]
socket = /opt/mysql/run/mysql.sock
[innotop]
socket = /opt/mysql/run/mysql.sock
[mysql]
prompt = \\u@\\d \\r:\\m:\\s>
no-auto-rehash
[mysqld_safe]
pid-file = /opt/mysql/run/mysqld.pid
[mysqld]
#### Baes dir ####
basedir = /opt/mysql
datadir = /data/mysql/data
tmpdir = /data/mysql/tmp
socket = /opt/mysql/run/mysql.sock
#### Base configure info ####
port = 3306
skip-name-resolve
old_passwords = 0
lower_case_table_names = 1
open_files_limit = 65535
read_rnd_buffer_size = 5M
max_allowed_packet = 24M
max_connect_errors = 50000
max_connections = 1000
max_user_connections = 950
thread_cache_size=64
table_open_cache=1024
thread_stack=262144
wait_timeout=864000
#### Log info ####
log-error = /data/mysql/log/alert.log
slow_query_log=1
slow_query_log_file= /data/mysql/log/slow.log
log-slow-admin-statements
long_query_time = 0.1
slow_launch_time=1
#### Binary log && Relay log ####
binlog_format='MIXED'
log-bin = /data/mysql/log/mysql-bin
log-slave-updates = 1
relay-log = /data/mysql/log/mysqld-relay-bin
relay-log-index = /data/mysql/log/mysqld-relay-bin.index
master-info-file = /data/mysql/log/master.info
relay-log-info-file = /data/mysql/log/relay-log.info
max_binlog_size = 500M
max_binlog_cache_size = 2G
#### query cache ####
query_cache_size = 100M
query_cache_limit = 1K
query_cache_min_res_unit = 1K
query_cache_type=2
#myisam
concurrent_insert = 2
key_buffer_size = 100M
sort_buffer_size = 100K
join_buffer_size = 100K
read_buffer_size = 1M
myisam_sort_buffer_size = 100M
#innodb plugin
#innodb
default-storage-engine = INNODB
innodb_flush_method = O_DIRECT
innodb_file_per_table = 1
innodb_open_files=60000
innodb_flush_log_at_trx_commit = 2
innodb_lock_wait_timeout = 100
innodb_additional_mem_pool_size = 20M
innodb_buffer_pool_size = 16G
innodb_log_buffer_size= 400M
innodb_log_file_size = 100M
innodb_log_files_in_group = 4
innodb_file_io_threads = 4
innodb_thread_concurrency = 16
innodb_max_dirty_pages_pct = 50
transaction-isolation = READ-COMMITTED
innodb_data_file_path = ibdata1:10G;ibdata2:5G:autoextend
innodb_buffer_pool_instances=4
innodb_thread_concurrency=32
### Server id ####
log_bin_trust_function_creators=1
read_only=0
server_id=5
8）创建数据库
[plain]
cd /opt/mysql
./scripts/mysql_install_db --user=mysql
上述建库语句将根据my.cnf里设置的数据文件目录和日志文件目录，生成相应的数据文件和日志文件，并创建系统数据库（如mysql,test,information_schema,performance_schema)
9）设置root密码，创建只读账号
[plain]
export PATH=$PATH:/opt/mysql/bin
mysqladmin -u root password '***'
mysql -uroot -p
root@(none) 06:08:34>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '***' WITH GRANT OPTION;
root@(none) 06:08:44>GRANT SELECT ON *.* TO 'rnd'@'%' IDENTIFIED BY '***';
10）最后，把MySQL加入系统启动项和开机启动
[plain]
cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld #把Mysql加入系统启动
chmod 755 /etc/init.d/mysqld #增加执行权限
chkconfig mysqld on #加入开机启动
这样，执行service mysqld start即可启动MySQL了：）。
