mysql 8.0.18 手工安装记录
为了日常方便，特记录如下。
一、安装系统依赖包
#1、系统依赖包安装 yum -y install make gcc-c++ cmake bison-devel ncurses-devel readline-devel libaio-devel perl libaio wget lrzsz vim libnuma* bzip2 xz
二、关闭防火墙和selinux
#2、关闭selinux sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config setenforce 0 #3、修改系统限制参数 cat >> /etc/security/limits.conf << EOF # ###custom # * soft nofile 20480 * hard nofile 65535 * soft nproc 20480 * hard nproc 65535 EOF
三、修改系统限制参数
修改系统限制参数 cat >>/etc/sysctl.conf <<"EOF" ################################## vm.swappiness=0 #增加tcp支持的队列数 net.ipv4.tcp_max_syn_backlog = 65535 #减少断开连接时 ，资源回收 net.ipv4.tcp_max_tw_buckets = 8000 net.ipv4.tcp_tw_reuse = 1 #net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_fin_timeout = 10 #改变本地的端口范围 net.ipv4.ip_local_port_range = 1024 65535 #允许更多的连接进入队列 net.ipv4.tcp_max_syn_backlog = 4096 #对于只在本地使用的数据库服务器 net.ipv4.tcp_fin_timeout = 30 #端口监听队列 net.core.somaxconn=65535 #接受数据的速率 net.core.netdev_max_backlog=65535 net.core.wmem_default=87380 net.core.wmem_max=16777216 net.core.rmem_default=87380 net.core.rmem_max=16777216 EOF sysctl -p
四、修改系统参数限制
# 修改系统限制参数 cat >>/etc/sysctl.conf <<"EOF" ################################## vm.swappiness=0 #增加tcp支持的队列数 net.ipv4.tcp_max_syn_backlog = 65535 #减少断开连接时 ，资源回收 net.ipv4.tcp_max_tw_buckets = 8000 net.ipv4.tcp_tw_reuse = 1 #net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_fin_timeout = 10 #改变本地的端口范围 net.ipv4.ip_local_port_range = 1024 65535 #允许更多的连接进入队列 net.ipv4.tcp_max_syn_backlog = 4096 #对于只在本地使用的数据库服务器 net.ipv4.tcp_fin_timeout = 30 #端口监听队列 net.core.somaxconn=65535 #接受数据的速率 net.core.netdev_max_backlog=65535 net.core.wmem_default=87380 net.core.wmem_max=16777216 net.core.rmem_default=87380 net.core.rmem_max=16777216 EOF sysctl -p
五、下载安装包
# 下载安装包：社区版 8.0.18 cd /opt/ wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
六、解压安装包
# 解压安装包 tar -xJf mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
cd /usr/local/
ln -s /opt/mysql-8.0.18-linux-glibc2.12-x86_64 mysql
七、创建用户
#7、创建用户 groupadd mysql useradd -g mysql mysql -d /home/mysql -s /sbin/nologin
八、创建对应的目录
#创建对应的目录 mkdir -p /data/mysql/mysql_3306/{data,logs,tmp,undolog}
九、创建配置文件
#9、创建my.cnf配置文件 # 排除干扰因素 if [ -f /etc/my.cnf ]; then mv /etc/my.cnf /etc/my.cnf.`date +%Y%m%d%H%M`.bak fi cat >/data/mysql/mysql_3306/my_3306.cnf <<"EOF" [client] port = 3306 #tee = "/data/mysql/mysql_3306/logs/mysql_output.log" socket = /data/mysql/mysql_3306/tmp/mysql_3306.sock [mysql] prompt="u@h R:m:s [d]> " no-auto-rehash [mysqld] user = mysql port = 3306 admin_address = 127.0.0.1 basedir = /usr/local/mysql datadir = /data/mysql/mysql_3306/data socket = /data/mysql/mysql_3306/tmp/mysql_3306.sock pid-file = mysql_3306.pid character-set-server = utf8mb4 skip_name_resolve = 1 #replicate-wild-ignore-table=mysql.% #replicate-wild-ignore-table=test.% #replicate-wild-ignore-table=information_schema.% # Two-Master configure #server-1 #auto-increment-offset = 1 #auto-increment-increment = 2 #server-2 #auto-increment-offset = 2 #auto-increment-increment = 2 # semi sync replication settings # #plugin_dir = /usr/local/mysql/lib/mysql/plugin #plugin_load = "validate_password.so;rpl_semi_sync_master=semisync_master.so;rpl_semi_sync_slave=semisync_slave.so" plugin_dir = /usr/local/mysql/lib/plugin #官方版本的路径 plugin_load = "rpl_semi_sync_master=semisync_master.so;rpl_semi_sync_slave=semisync_slave.so" #官方版本的路径 slave_parallel_workers = 8 slave_parallel_type = LOGICAL_CLOCK open_files_limit = 65535 back_log = 1024 max_connections = 1024 max_connect_errors = 1000000 table_open_cache = 1024 table_definition_cache = 1024 table_open_cache_instances = 64 thread_stack = 512K external-locking = FALSE max_allowed_packet = 32M sort_buffer_size = 4M join_buffer_size = 4M thread_cache_size = 1536 interactive_timeout = 600 wait_timeout = 600 tmp_table_size = 32M max_heap_table_size = 32M slow_query_log = 1 log_timestamps = SYSTEM slow_query_log_file = /data/mysql/mysql_3306/logs/slow.log log-error = /data/mysql/mysql_3306/logs/error.log long_query_time = 0.1 log_queries_not_using_indexes =1 log_throttle_queries_not_using_indexes = 60 min_examined_row_limit = 100 log_slow_admin_statements = 1 log_slow_slave_statements = 1 server-id = 3306 log-bin = /data/mysql/mysql_3306/logs/mysql-bin sync_binlog = 1 binlog_cache_size = 4M max_binlog_cache_size = 2G max_binlog_size = 1G # binlog_expire_logs_seconds=2592000 master_info_repository = TABLE relay_log_info_repository = TABLE gtid_mode = on enforce_gtid_consistency = 1 log_slave_updates #slave-rows-search-algorithms = 'INDEX_SCAN,HASH_SCAN' binlog_format = row binlog_row_image=FULL binlog_checksum = 1 relay_log_recovery = 1 relay-log-purge = 1 key_buffer_size = 32M read_buffer_size = 8M read_rnd_buffer_size = 8M bulk_insert_buffer_size = 64M myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 lock_wait_timeout = 3600 explicit_defaults_for_timestamp = 1 innodb_thread_concurrency = 0 innodb_sync_spin_loops = 100 innodb_spin_wait_delay = 30 #transaction_isolation = REPEATABLE-READ transaction_isolation = READ-COMMITTED #innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 45875M innodb_buffer_pool_instances = 4 innodb_buffer_pool_load_at_startup = 1 innodb_buffer_pool_dump_at_shutdown = 1 innodb_data_file_path = ibdata1:1G:autoextend innodb_flush_log_at_trx_commit = 1 innodb_log_buffer_size = 32M innodb_log_file_size = 2G innodb_log_files_in_group = 3 innodb_max_undo_log_size = 4G innodb_undo_directory = /data/mysql/mysql_3306/undolog # 根据您的服务器IOPS能力适当调整 # 一般配普通SSD盘的话，可以调整到 10000 -
