error : Dependency detection failed :
net-tools By MySQL-server-5.5.62-1.el7.x86_64 need
perl(Data::Dumper) By MySQL-server-5.5.62-1.el7.x86_64 need


It's missing net-tools


Two 、 Check if you have this bag :

yum list|grep -i net-tools

[[email protected] java]# yum list|grep -i net-tools

default-character-set =utf8mb4
# MySQL The server monitors by default TCP/IP port
port = 3306
# # Set the default storage engine to InnoDB
# MySQL Server character set
# MySQL Server character set
collation_server = utf8mb4_general_ci
# Library name 、 Whether the table name is case sensitive . The default is 0, Set up 1, Case insensitive , Create a table 、 Databases are stored in lower case on disks .
# MySQL Software installation path
# MySQL Data file storage path
# For local connection Unix Socket file storage path
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M


twenty 、 restart mysql

# Two master databases are slaves to each other
# Without the following configuration , There is a slave library that does not synchronize data , Only 2 Main library 、1 Synchronization of slave Libraries
# Whether the slave library is written to the binary log . If you need to be a multi master, you can enable . Read only, you don't need to
# The initial value of the server auto increment column .( And Master2,...... MasterN The difference between ), As the Lord 1 The value of is 1, Then the Lord 2 The value of is 2
# The server will increment columns automatically . The default value is 1, The value range is 1 .. 65535
===== Two masters and two slaves end =====
#===== Master slave copy Main library end =====
# ===== Master slave copy Slave Library Start =====
# Set up the database to be synchronized
# Shield system library synchronization
# ===== Master slave copy Slave Library end =====
View firewall status :
