網易cetus數據庫中間件安裝-讀寫分離版本

安裝前提：一、數據庫主從關係要作好；二、受權用戶登陸要作好；三、mysql最大鏈接數設置好，否則會報鏈接錯誤；四、版本最好是5.6以上。

一、安裝依賴

yum install cmake gcc glib2-devel flex libevent-devel mysql-devel gperftools-libs -y

二、下載源碼

cd /root/tools && git clone https://github.com/Lede-Inc/cetus.git

三、編譯安裝

cd cetus/ && mkdir build/ && cd build/
   cmake ../ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=/usr/local/cetus -DSIMPLE_PARSER=ON && make install

四、配置文件

cd /usr/local/cetus/conf/ &&  cp -rp proxy.conf.example  proxy.conf &&cp users.json.example  users.json && chmod 660 conf/proxy.conf

vim users.json

{
    "users":    [{
            "user": "用於登陸mysql的帳戶",
            "client_pwd":   "用於登陸mysql的密碼",
            "server_pwd":   "用於登陸mysql的密碼"
        }]
}

vim proxy.conf

[cetus]
# For mode-switch
daemon = true

plugins=proxy,admin

# Defines the number of worker processes.

# File and Log Configuration, put log in /data and marked by proxy port, /data/cetus needs to be created manually and has rw authority for cetus os user
max-open-files = 65536

5 主庫建立心跳錶

create database if not exists proxy_heart_beat; use proxy_heart_beat;
CREATE TABLE if not exists tb_heartbeat ( p_id varchar(128) NOT NULL , p_ts timestamp(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3), PRIMARY KEY (p_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

六、啓動

/usr/local/cetus/bin/cetus --defaults-file=/usr/local/cetus/conf/proxy.conf ;tailf logs/cetus_6001.log
