pxc测试机搭建过程

环境：

[root@pxc23 ~]# uname -r2.6.39-400.17.1.el6uek.x86_64

192.168.56.21

192.168.56.22

192.168.56.23

1、下载：

http://www.percona.com/redir/downloads/Percona-XtraDB-Cluster/LATEST/binary/tarball/Percona-XtraDB-Cluster-5.5.39-rel36.0-25.11.828.Linux.x86_64.tar.gz

2、解压

tar -xzvf Percona-XtraDB-Cluster-5.5.39-rel36.0-25.11.828.Linux.x86_64.tar.gz -C /usr/local
ln -sf /usr/local/Percona-XtraDB-Cluster-5.5.39-rel36.0-25.11.828.Linux.x86_64 /usr/local/mysql

3、检测依赖包

[root@oel64 tmp]#  ldd /usr/local/mysql/bin/mysqld
linux-vdso.so.1 =>  (0x00007fff2d1ff000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x000000395f200000)
libaio.so.1 => /lib64/libaio.so.1 (0x000000395ea00000)
libz.so.1 => /lib64/libz.so.1 (0x000000395fa00000)
librt.so.1 => /lib64/librt.so.1 (0x000000395fe00000)
libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0000003961e00000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f75a20be000)
libssl.so.6 => not found
libcrypto.so.6 => not found
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003963600000)
libm.so.6 => /lib64/libm.so.6 (0x000000395f600000)
libc.so.6 => /lib64/libc.so.6 (0x000000395ee00000)
/lib64/ld-linux-x86-64.so.2 (0x000000395e600000)
libfreebl3.so => /lib64/libfreebl3.so (0x0000003961a00000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003962e00000)

安装依赖包

[root@oel64 tmp]# locate libssl.so libcrypto.so.10
/usr/lib64/.libcrypto.so.10.hmac
/usr/lib64/.libssl.so.1.0.0.hmac
/usr/lib64/.libssl.so.10.hmac
/usr/lib64/libcrypto.so.10
/usr/lib64/libssl.so.1.0.0
/usr/lib64/libssl.so.10


已有更高的版本，直接建个软链就可以了
ln -s /usr/lib64/libcrypto.so.10 /usr/lib64/libcrypto.so.6
ln -s /usr/lib64/libssl.so.10 /usr/lib64/libssl.so.6

4、用户

groupadd -r -g 306 mysql           #-r表示是伪用户，只是用来运行mysql程序，不能登录系统  
useradd -g 306  -r  -u 306 mysql

5、path

[root@OELX64 mysql]# cat ~/.bash_profile 
... ...
PATH=/usr/local/mysql/bin:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
export PATH

6、my.cnf

下面参数，测试机用，正式环境请测试验正后再用

cat /etc/my.cnf

[client]socket                         = /tmp/user_3306.sockuser                           = mysqlport                           = 3306[mysql]#prompt="\\u@\\h:\\p  [\\d]> "prompt="\\p>"#pager="less -i -n -S"#tee=/home/mysql/query.logno-auto-rehash[mysqld]#miscuser                           = mysqlbasedir                        = /usr/local/mysqldatadir                        = /data/mysql/user_3306/datatmpdir                         = /data/mysql/user_3306/tmpport                           = 3306socket                         = /tmp/user_3306.sockserver_id                      = 213306lower_case_table_names         = 1#timeoutinteractive_timeout = 300wait_timeout        = 300#character setcharacter-set-server = utf8open_files_limit = 65535max_connections = 100max_connect_errors = 100000#logslog-output= fileslow_query_log= 1slow_query_log_file= slow.loglog-error= error.loglog_warnings= 2pid-file= mysql.pidlong_query_time= 1#log-slow-admin-statements= 1#log-queries-not-using-indexes= 1log-slow-slave-statements= 1#binlogbinlog_format= rowlog-bin= mysql-binbinlog_cache_size= 1Mmax_binlog_size= 200Mmax_binlog_cache_size= 2Gsync_binlog= 0expire_logs_days= 10#relay logskip_slave_start= 1max_relay_log_size= 500Mrelay_log_purge= 1relay_log_recovery= 1log_slave_updates= 1#slave-skip-errors=1032,1053,1062#buffers & cachetable_open_cache = 2048table_definition_cache = 2048table_open_cache = 2048max_heap_table_size = 96Msort_buffer_size = 2Mjoin_buffer_size = 2Mthread_cache_size = 256query_cache_size = 0query_cache_type = 0query_cache_limit = 256Kquery_cache_min_res_unit = 512thread_stack = 192Ktmp_table_size = 96Mkey_buffer_size = 8Mread_buffer_size = 2Mread_rnd_buffer_size = 16Mbulk_insert_buffer_size = 32M#myisammyisam_sort_buffer_size = 128Mmyisam_max_sort_file_size = 10Gmyisam_repair_threads = 1#innodbinnodb_buffer_pool_size = 100Minnodb_buffer_pool_instances = 1innodb_data_file_path = ibdata1:100M:autoextendinnodb_flush_log_at_trx_commit = 2innodb_log_buffer_size = 64Minnodb_log_file_size = 256Minnodb_log_files_in_group = 3innodb_max_dirty_pages_pct = 90innodb_file_per_table = 1innodb_rollback_on_timeoutinnodb_status_file = 1innodb_io_capacity = 2000transaction_isolation = READ-COMMITTEDinnodb_flush_method = O_DIRECT#pxcdefault_storage_engine=Innodbinnodb_locks_unsafe_for_binlog=1innodb_autoinc_lock_mode=2wsrep_cluster_name=pxc_jz  #cluster的名字 wsrep_cluster_address=gcomm://192.168.56.21,192.168.56.22,192.168.56.23 #cluster 中的节点ip wsrep_node_address=192.168.56.21 #cluster当前节点的 ip wsrep_provider=/usr/local/mysql/lib/libgalera_smm.so#wsrep_sst_method=rsyncwsrep_sst_method=xtrabackupwsrep_sst_auth=sst:26856649sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

server_id                      = 213306
wsrep_node_address=192.168.56.21 #cluster当前节点的 ip 
不同的机子，改上面这两个参数

7、建库

rm /data/mysql/user_3306/ -rf
mkdir /data/mysql/user_3306/data -p
mkdir /data/mysql/user_3306/logs -p
mkdir /data/mysql/user_3306/tmp -p
chown -R mysql:mysql /data/mysql/*


cd /data/mysql/user_3306/data/
openssl genrsa -out private_key.pem 1024
openssl rsa -in private_key.pem -pubout > public_key.pem
chmod 444 public_key.pem
chmod 444 private_key.pem
chown mysql:mysql public_key.pem
chown mysql:mysql private_key.pem


cd /usr/local/mysql
# 必须在mysql目录下执行
scripts/mysql_install_db --user=mysql  --defaults-file=/etc/my.cnf


cp /usr/local/mysql/support-files/mysql.server /data/mysql/user_3306/ 
chown -R mysql:mysql /data/mysql/*
cd /data/mysql/user_3306/


启动时要注意第一个节点：
./mysql.server bootstrap-pxc
其它节点
./mysql.server start

安装完成，去测试同步吧
