zookeeper 伪集群安装和 zkui管理UI配置

#=======================【VM机器,二进制安装】

# 安装环境
# OS System = Linux CNT7XZKPD02 4.4.190-1.el7.elrepo.x86_64 #1 SMP Sun Aug 25 07:32:44 EDT 2019 x86_64 x86_64 x86_64 GNU/Linux

# JDK = java version "1.8.0_231" / Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

# zookeeper = zookeeper-3.6.1-x64

# zkui = zkui-2.0 , 备注：main.java有修复一个bug关于config.cfg路径获取。

#========================install zookeeper========================================================================                                              

# step  设置系统swap 分区大小，参考如下公式：

# RAM                    /     Swap Space

# Between  GB and  GB  /     1.5 times the size of the RAM

# Between  GB and  GB /     Equal to the size of the RAM

# More than  GB        /      GB

# 执行如下命令

# 然后，检查和设置swap那一行是否有被注释，如果被注释就要开启

cat /etc/fstab

# 查看swap 空间大小(总计)：

free -m

# 查看swap 空间(file(s)/partition(s))：

swapon -s

# 查看磁盘路径的空间

df -h /home

# 关闭所有的swap空间

swapoff -a

# 创建新的swap文件，bs=表示每个block分块大小是1024 byte，count表示多少个block分块，所以总大小是bs*count=4GB

dd if=/dev/zero of=/home/system-swap bs= count=

# 输出如下

# + records in

# + records out

#  bytes (4.3 GB) copied, 29.991 s,  MB/s

# 设置这个分区的权限为600

chmod -R  /home/system-swap

# 把这个新建分区，变成swap分区

/sbin/mkswap /home/system-swap

# 输出如下

# Setting up swapspace version , size =  KiB

# no label, UUID=941e36a8-d389--ad7d-07387e1da776

# 把这个新建分区，设置状态为open。

# 备注：重启之后，该swap分区还是失效，只有执行下面配置后才会永久生效。

/sbin/swapon /home/system-swap

# 设置重启后，swap分区仍然有效

# 编辑如下文件，修改swap行内容为新加分区/home/system-swap

cat /etc/fstab

##### /dev/mapper/centos-swap swap                    swap    defaults

# /home/system-swap  swap                    swap    defaults         

# 关闭SELINUX，设置参数SELINUXTYPE=disabled

vi /etc/selinux/config

# 修改参数如下

# # SELINUXTYPE=targeted

SELINUXTYPE=disabled

# =============================================================================================================

# step : 安装系统依赖软件

# 修改yum为国内镜像 === 看具体情况，有时候国内镜像不一定完整，这个时候还是要切换回国外地址

# cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup-linux && \

# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo && \

yum clean all && \

yum makecache

# 清理掉无用的repo

yum --enablerepo=base clean metadata

# 安装依赖软件

yum install binutils -y && \

yum install compat-libstdc++- -y && \

yum install gcc -y && \

yum install gcc-c++ -y && \

yum install glibc -y && \

yum install glibc-devel -y && \

# yum

rpm -q --queryformat %-{name}-%{version}-%{release}-%{arch}"\n" \ compat-libstdc++- glibc-kernheaders glibc-headers libaio libgcc glibc-devel xorg-x11-deprecated-libs

# libaio-0.3.-.el7-x86_64

# libgcc-4.8.-.el7-x86_64

# package glibc-devel is not installed

# package xorg-x11-deprecated-libs is not installed

# 遇到部分无法在aliyun下载的软件，则需要重新替换yum.repo

# cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup-aliyun && \

# cp /etc/yum.repos.d/CentOS-Base.repo.backup-linux /etc/yum.repos.d/CentOS-Base.repo && \

# 确保，已经包含了libaio-0.3.，默认开启异步I/O。

# 检查在操作系统中，是否开启AIO 异步读写IO

cat /proc/slabinfo | grep kio

# 如果没有开启，则在下面文件中，增加如下两行

vi /proc/slabinfo

kioctx                     : tunables           : slabdata

kiocb                       : tunables          : slabdata              

# =============================================================================================================

# step : 创建zookeper安装目录

mkdir -p /opt/soft/{jdk,zookeeper}

# 然后上传jdk或zookeeper 二进制文件到上面创建的软件目录

# 创建zookeeper的安装主目录

mkdir -p /app/zookeeper && \

# 创建zookeeper的数据主目录

mkdir -p /data/zookeeper && \

# 创建zookeeper的日志主目录

mkdir -p /log/zookeeper

# =============================================================================================================

# step : zookeeper安装用户和组的创建

# 使用root用户，进行如下操作：

# 创建ops_install组

groupadd  -g  ops_install

# 创建ops_admin组

groupadd  -g  ops_admin

# 创建zookeeper用户

useradd -g ops_install  -G  ops_admin  zookeeper

# 修改zookeeper密码

echo 'password'|passwd --stdin zookeeper

# 删除用户和其以来的用户文件

# userdel -r zookeeper

# 查看用户zookeeper权限是否设置正确，正确输出结果如下

# id zookeeper

# [root@CNT7XZKPD02 ~]# id zookeeper

# uid=(zookeeper) gid=(ops_install) groups=(ops_install),(ops_admin)

# =============================================================================================================

# step : 安装用户的profile文件的设置

# 编辑/etc/profile，加入以下内容

vi /etc/profile

# -----------------------java env-----------------------------------------------------------------

JAVA_HOME=/env/jdk/jdk-12.0.

PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

# -----------------------zookeeper env---------------------------------------------------------------

# 生效配置环境变量

source /etc/profile

# 检查生效环境变量

env | grep ZOOKEEPER

env | grep JAVA

# =============================================================================================================

# step : 安装jdk

# 创建jdk的软件目录和安装目录，分别如下：

mkdir -p /opt/soft/jdk/ && \

mkdir -p /env/jdk/

# 然后，通过WinSCP工具，把JDK 8二进制安装包tar复制到软件目录

ls -al /opt/soft/jdk/jdk-12.0.2_linux-x64_bin.tar.gz

# 解压jdk到安装目录

tar -zxvf /opt/soft/jdk/jdk-12.0.2_linux-x64_bin.tar.gz -C /env/jdk/

# SOURCE = https://github.com/DeemOpen/zkui.git

# git clone https://github.com/DeemOpen/zkui.git

# 2. 创建zkui的linux服务器的安装目录

mkdir -p /app/zkui/zkui-2.0

# 复制zkui-2.0-SNAPSHOT.jar文件到此目录u

ls -al /app/zkui/zkui-2.0/zkui-2.0-SNAPSHOT.jar

# 3. 创建zkui的配置文件，如下

# 注意：zkui的安装，可以和zookeeper服务器不在同一台服务器上。

cat > /app/zkui/zkui-2.0/config.cfg <<EOF

# 4. 添加zookeeper账户对安装目录的权限

ls -al /app/zkui/zkui-2.0/ && \

chmod -R 775 /app/zkui/zkui-2.0/ && \

chown -R zookeeper:ops_install /app/zkui/zkui-2.0/ && \

ls -al /app/zkui/zkui-2.0/

# 4. 启动zkui，如下

java -Xms128m -Xmx512m -XX:MaxMetaspaceSize=256m -jar /app/zkui/zkui-2.0/zkui-2.0-SNAPSHOT-jar-with-dependencies.jar

# 5. 设置开机自动启动，如下

cat > /etc/systemd/system/zkui.service <<EOF
