摘要：修改主機(jī)名主機(jī)名服務(wù)器磁盤(pán)掛載將磁盤(pán)掛載修改為方式初始化服務(wù)器安裝程序下載，根據(jù)需求安裝所需與執(zhí)行初始化腳本基礎(chǔ)工作常用類(lèi)庫(kù)常用軟件配置設(shè)置前綴為解除與前綴的對(duì)應(yīng)關(guān)系

1.修改主機(jī)名

vim /etc/hostname
vim /etc/hosts 
hostname <主機(jī)名>

2.服務(wù)器磁盤(pán)掛載

vim /data/scripts/auto_fdisk.sh

3.將磁盤(pán)掛載修改為uuid方式

blkid /dev/xvdb1
vim /etc/fstab
 UUID=41852b97-3630-42b1-b2ae-9d8f77922245 /data ext4 defaults 1 2

4.初始化服務(wù)器

#!/bin/sh
yum clean all
systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i "s/enforcing/disabled/g" /etc/selinux/config
yum -y install vim openssh* ntp wget screen bash-completion git
service ntpd stop
ntpdate time.nist.gov
sed -i "s/0.centos.pool.ntp.org/time.nist.gov/g" /etc/ntp.conf
chkconfig ntpd on
service ntpd restart

5.安裝程序

下載oneinstack，根據(jù)需求安裝所需memcached與supervisord

6.執(zhí)行cache初始化腳本

#!/bin/sh -e

########## 1. 基礎(chǔ)工作 start ##########

tmux_conf=/root/.tmux.conf

chk_service_super=`systemctl status supervisord.service | grep inactive`
if [[ -n $chk_service_super ]]
then
    echo "supervisord is inactive..."
else
    sudo service supervisord stop
fi

chk_service_hhvm=`systemctl status hhvm | grep inactive`
if [[ -n $chk_service_hhvm ]]
then
    echo "hhvm is inactive..."
else
    sudo service hhvm stop
fi

# 常用類(lèi)庫(kù)
sudo yum -y install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
# 常用軟件
sudo yum -y install net-tools unzip vim lrzsz subversion tmux

# tmux配置
cat > $tmux_conf <
7.配置supervisord
7.1 啟動(dòng)supervisord服務(wù)
service supervisord start
7.2 修改supervisord配置文件
vim /etc/supervisord.conf

修改如下信息：
[include]
files = supervisord.d/*.ini

#[program:hhvm]
#command=/usr/bin/hhvm --mode server --user www --config /etc/hhvm/server.ini --config /etc/hhvm/php.ini --config /etc/hhvm/config.hdf
#numprocs=1 ; number of processes copies to start (def 1)
#directory=/tmp ; directory to cwd to before exec (def no cwd)
#autostart=true ; start at supervisord start (default: true)
#autorestart=unexpected ; whether/when to restart (default: unexpected)
#stopwaitsecs=10 ; max num secs to wait b4 SIGKILL (default 10)
7.4 添加memcached信息
vim /etc/supervisord/mc_11211.ini
vim /etc/supervisord/mc_11212.ini
vim /etc/supervisord/mc_11213.ini
添加如下信息
[program:mc_11211]
command=/usr/local/memcached/bin/memcached -p 11211 -u memcached -m 2048 -c 10240 -l 10.0.0.51
user=root                                ;執(zhí)行命令的用戶(hù)
numprocs=1                            ; 啟動(dòng)幾個(gè)進(jìn)程 默認(rèn) 1
#process_name=%(process_num)02d
;directory=                              ; 執(zhí)行前要不要先cd到目錄去
autostart=true                          ; 隨著supervisord的啟動(dòng)而啟動(dòng)
autorestart=true                        ; 是否自動(dòng)重啟 默認(rèn)true
startretries=5                          ; 啟動(dòng)失敗時(shí)的最多重試次數(shù) 默認(rèn)5
;;exitcodes=0                            ; 正常退出代碼
;;stopsignal=KILL                         ; 用來(lái)殺死進(jìn)程的信號(hào)
;;stopwaitsecs=10                        ; 發(fā)送SIGKILL前的等待時(shí)間
redirect_stderr=true                     ; 重定向stderr到stdout
stdout_logfile=/data/logs/error/supervisor/mc_11211.log
stderr_logfile=/data/logs/error/supervisor/mc_11211.log
8.最終配置
關(guān)閉防火墻服務(wù)
systemctl stop firewalld.service
systemctl disable firewalld.service
關(guān)閉memcached服務(wù)
service memcached stop
關(guān)閉memcached開(kāi)機(jī)自啟
chkconfig memcached off
重啟supervisord，采用supervisord啟動(dòng)memcached
service supervisord restart
