MySQL server的搭建
无意间发现之前搭建MySQL的时候，有将操作过程记录下来，涉及主机系统配置修改，MySQL用户和目录创建，初始化等操作。未免日后遗忘，特保存在这里。有些步骤可能会有错，需要甄别。注：mysql-5.7.9
1、关闭防火墙和SELINUX
2、建立mysql用户组和用户
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql
3、 配置系统内核参数，增加如下配置
# vim /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6553560
启用刚刚所做的变更， 输入命令： # /sbin/sysctl -p
4、修改系统资源限制编辑系统资源限制配置文件 vim /etc/security/limits.conf，在该文件下添加
如下行：
# vim /etc/security/limits.conf
mysql soft nproc 2047
mysql hard nproc 16384
mysql soft nofile 1024
mysql hard nofile 65536
编辑 vim /etc/profile 文件，添加如下行
ulimit -u 16384 -n 65536
5、执行cmake命令，生成编译配置文件
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=../boost_1_59_0 \
-DSYSCONFDIR=/etc \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DENABLE_DTRACE=0 \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DWITH_EMBEDDED_SERVER=1
编译安装 make && make install
6、修改mysql所在目录的所有者为mysql用户
chown -R mysql.mysql /usr/local/mysql
7、创建mysql数据目录
mkdir -p /data/mysql
chown -R mysql.mysql /data/mysql
8、设置mysql开机启动
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig mysqld on
vi /etc/profile 默认mysql命令路径，增加如下内容
export PATH=/usr/local/mysql/bin:$PATH
执行source使路径生效source /etc/profile
9、创建my.cnf文件，添加如下内容vi /etc/my.cnf
port = 3306
socket = /tmp/mysql.sock
default-character-set = utf8mb4
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/mysql

pid-file = /data/mysql/mysql.pid
user = mysql
bind-address = 0.0.0.0
server-id = 1
init-connect = 'SET NAMES utf8mb4'
character-set-server = utf8mb4

#skip-networking

max_allowed_packet = 4M
binlog_cache_size = 1M
max_heap_table_size = 8M
tmp_table_size = 16M
read_buffer_size = 2M
read_rnd_buffer_size = 8M
sort_buffer_size = 8M
join_buffer_size = 8M
key_buffer_size = 4M
thread_cache_size = 8
query_cache_type = 1
query_cache_size = 8M
query_cache_limit = 2M
ft_min_word_len = 4
log_bin = mysql-bin
binlog_format = mixed
expire_logs_days = 30
log_error = /data/mysql/mysql-error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /data/mysql/mysql-slow.log
performance_schema = 0
explicit_defaults_for_timestamp
#lower_case_table_names = 1
skip-external-locking
default_storage_engine = InnoDB
#default-storage-engine = MyISAM
innodb_file_per_table = 1
innodb_open_files = 500
innodb_buffer_pool_size = 64M
innodb_write_io_threads = 4
innodb_read_io_threads = 4
innodb_thread_concurrency = 0
innodb_purge_threads = 1
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 2M
innodb_log_file_size = 32M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
bulk_insert_buffer_size = 8M
myisam_sort_buffer_size = 8M
myisam_max_sort_file_size = 10G
myisam_repair_threads = 1

wait_timeout = 28800
quick
max_allowed_packet = 16M
key_buffer_size = 8M
sort_buffer_size = 8M
read_buffer = 4M
write_buffer = 4M
EOF
10、初始化数据库
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
11、启动mysql数据库
service mysqld start
