一、環境介紹：
系統：Cerntos6.6
Mysql版本：mysql-5.6.34
二、安裝操作：
1、卸載舊版本：
rpm -qa |grep mysql mysql-server-5.1.73-8.el6_8.x86_64 mysql-libs-5.1.73-8.el6_8.x86_64 mysql-5.1.73-8.el6_8.x86_64 刪除/etc/my.cnf: rm -f /etc/my.cnf rpm -e mysql-libs-5.1.73-8.el6_8.x86_64 mysql-5.1.73-8.el6_8.x86_64 --nodeps #強制刪除
注：在CentOS 6.4版操作系統最小安裝完成后，默認會在/etc目錄下存在一個my.cnf，需要將此文件更名為其他的名字，如：/etc/my.cnf.bak，否則，該文件會干擾源碼安裝的MySQL的正確配置，造成無法啟動。
在使用"yum update"更新系統后，需要檢查下/etc目錄下是否會多出一個my.cnf，如果多出，將它重命名成別的。否則，MySQL將使用這個配置文件啟動，可能造成無法正常啟動等問題。
2、安裝依賴包：
yum -y install make gcc-c++ cmake bison-devel ncurses-devel groupadd mysql #有用戶的話刪除就行 userdel mysql useradd -g mysql mysql -M -s /sbin/nologin
3、下載MySQL，源碼編譯安裝：
cd /usr/local/src 下載安裝包： 百度雲盤鏈接：http://pan.baidu.com/s/1hs8awRU 密碼：ly4d tar -zxvf mysql-5.6.34.tar.gz cd mysql-5.6.34/ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci make && make install
4、配置MySQL：
修改/usr/local/mysql權限 mkdir -p /data/mysql/data chown -R mysql:mysql /usr/local/mysql chown -R mysql:mysql /data/mysql/data 執行初始化配置腳本，創建系統自帶的數據庫和表 cd /usr/local/mysql ./scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data --user=mysql #如果后續不小心刪除了這個數據目錄或這個目錄下的文件被誤操作刪除了，可以利用這個命令重新初始化。 cp support-files/mysql.server /etc/init.d/mysql chkconfig mysql on service mysql start //啟動前，要先配置my.cnf文件（如下）， 並確保/data/mysql/data和/usr/local/mysql的mysql權限
[client] port = 3306 socket = /usr/local/mysql/var/mysql.sock [mysqld] port = 3306 socket = /usr/local/mysql/var/mysql.sock basedir = /usr/local/mysql/ datadir = /data/mysql/data pid-file = /data/mysql/data/mysql.pid user = mysql bind-address = 0.0.0.0 server-id = 1 sync_binlog=1 log_bin = mysql-bin skip-name-resolve back_log = 600 max_connections = 3000 max_connect_errors = 3000 table_open_cache = 512 max_allowed_packet = 16M binlog_cache_size = 16M max_heap_table_size = 16M tmp_table_size = 256M read_buffer_size = 1024M read_rnd_buffer_size = 1024M sort_buffer_size = 1024M join_buffer_size = 1024M key_buffer_size = 8192M thread_cache_size = 8 query_cache_size = 512M query_cache_limit = 1024M ft_min_word_len = 4 binlog_format = mixed expire_logs_days = 30 log_error = /data/mysql/data/mysql-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /data/mysql/data/mysql-slow.log performance_schema = 0 explicit_defaults_for_timestamp skip-external-locking default_storage_engine = InnoDB innodb_file_per_table = 1 innodb_open_files = 500 innodb_buffer_pool_size = 1024M innodb_write_io_threads = 1000 innodb_read_io_threads = 1000 innodb_thread_concurrency = 8 innodb_purge_threads = 1 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 4M 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 interactive_timeout = 28800 wait_timeout = 28800 [mysqldump] quick max_allowed_packet = 16M [myisamchk] key_buffer_size = 8M sort_buffer_size = 8M read_buffer = 4M write_buffer = 4M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES port = 3306
啟動報錯的話：
[root@localhost mysql]# ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) 登錄報以上錯誤的話，刪除/var/lib/mysql/mysql.sock這個文件： rm -f /var/lib/mysql/mysql.sock ln -s /usr/local/mysql/var/mysql.sock /var/lib/mysql/mysql.sock
